You give the dimensions and positions of each element, and the program calculates gain, input impedance, front-to back ratio, beam-patterns etc. An optimisation program 'optimise' tries to optimise a design. The optimiser can also tell you the sensitivity of a good design, to small mechanical errors. AUTHOR: Dr. David Kirkby B.Sc. M.Sc.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. yagiuda-1.19.orig/ChangeLog0000644000175000017500000001165010264167713014102 0ustar pg4ipg4iVersion 1.0 26th Sept 1994. This was the first version put onto the anonymous ftp server medphys.ucl.ac.uk Version 1.01 30th Sept 1994. This corrected a number of problems with the original code, so that it now runs properly on the acc (Sun ANSI C) and gcc (GNU C/C++) compilers. The original version only compiled properly only on g++ (GNU C++) and CC (Sun C++) compilers. Version 1.02 14 Oct 1994 This release corrected a number of memory allocation errors in 'yagi', 'output' and 'optimise'. Memory was not always freed in earlier releases. Also, a for loop in all 3 programs had a calls to routines which allocated memory many times, when it was only needed once. The output file now has # to mark comments, which the gnuplot (GNU plotting program) recognises. Version 1.03 'optimise' was compleatly re-written, so that it no longer used lots of tempory files on disk. This makes it much faster (6-7x on a 6ele beam ). Version 1.04 First DOS based version. Version 1.05 26 Oct 1994. Optimise now takes lots of options. You dont need such a complex command to get it to work. There are sensible defaults. Some options dont work on optimise - '-g' , '-T' , -t' and '-p'. Version 1.06 28/10/94 Released on to one user. Options 'T' and 't' now work. Genetic algorithm still does, although man page mention them. Version 1.07 31/10/94 Added option '-w' that averages data of 3 frequencies to build wide-band antenna. A lot of integers for best/latest design were removed, puting them instead in a structure. Version 1.08 5/11/94. Genetic algorithm works now. Parameters used internally (probability of crossover etc) may not be anywhere near optimum. GA does not seem to offer any real advantage, but early days yet. Added a new program 'rantest' to check the randome number generators are working okay. Version 1.09 Added a facility in 'output' to print 3dB bandwidths. Removed printing of parameter 'F', as this is of little use and space is needed. Changed default elements altering form only parasitic to all elements. Corrected an error in which the .gai file prints the E-plane data and H-plane data refersed. Version 1.10 Thursday 3 October 1995. Corrected a bug where 'output' would fail, due to a problem with assuming where the 3dB points were in the H plane. Added options '-i' so you can completely ignore 3dB beamwidths, also options '-E' and '-H' so you can specify the maximum value of theta and phi over which the beamwidths are calculated. A better fix, wherby the program always gets it right will possibly be added, but this will slow the program considerably. Needs some though of the best way to do this. Program now computes the maximum level of any sidelobe. Obviously there no point worrying about getting a good FB, if one of the other lobes is more significant. Version 1.11 Never released. Changed most of the things done in 1.10! The '-i' option on optimise has been droped, but insread a '-e' option was added to avoid calculation of the E-palne BW and a -h to avoid calculation of the H-plane BW. Version 1.12 Changed GA length. eg min length can now go below 0.4 lambda. Changed program 'first; to calculate the according to the well known DL6WU antennnas. fitness computed in a different was. weight.swr=1-log10(swr), rather than the old 1-((swr-1)/(swr+1))^2.*weight.gain. 'yagi' now prints the element currents, as a row of *'s, if the -d option is added. Version 1.13 16th Oct 2000 Much improved documentation. There are now some html files on my web site, plus all the man pages are now also in html. The code has not changed much since the last vesion Version 1.14 20th October 2000 The main change on this version has been the introduction of the 'configure' scripts, which should make the programme easier to build. Some minor changes to the docs have been made, to keep them upto date. Version 1.15 21st October 2000 Corrected an error, whereby the file 'version.c' was linked into yagi twice. Corrected a bug in yagi.c, whereby the dflg was not initiallised to 0. Version 1.16 23rd October 2000 Added a -p option to output, which generates data for gnuplot. Updated the man pages correcting a few spelling errors in the process. Version 1.18 29/10/2000 Generate output for gnuplot on a linear scale in addition to a log scale Changed the names of a few files, to be more explicit Cleaned up a lot of code, so gcc generates far less warnings. Corrected a bug in first.c so that it works okay for non-uniform diamater elements. included stdlib.h if possible in all files, to remove a linux bug Correct a few spelling errors in first and input. Changed input so it can handle antennas with different diameter elements. Version 1.18 10/7/2005 Added a new program 'dipole' to compute slef Z of dipole Changed the file structure layout, so docs are better organinsed made new directories man, man/man1 and man/man5 moved .1 and .5 files to the respective directories. Added a couple of files that prevented 'make distcheck' from working. yagiuda-1.19.orig/INSTALL0000644000175000017500000001722707176260026013366 0ustar pg4ipg4iBasic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. You can give `configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not supports the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `configure' also accepts some other, not widely useful, options. yagiuda-1.19.orig/Makefile.am0000644000175000017500000000006110264166350014352 0ustar pg4ipg4iSUBDIRS = . src doc man EXTRA_DIST = BUGS TODO yagiuda-1.19.orig/Makefile.in0000644000175000017500000003553310264170227014375 0ustar pg4ipg4i# Makefile.in generated by automake 1.7 from Makefile.am. # @configure_input@ # Copyright 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002 # Free Software Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ srcdir = @srcdir@ top_srcdir = @top_srcdir@ VPATH = @srcdir@ pkgdatadir = $(datadir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ top_builddir = . am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd INSTALL = @INSTALL@ install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : ACLOCAL = @ACLOCAL@ ALLOCA = @ALLOCA@ AMDEP_FALSE = @AMDEP_FALSE@ AMDEP_TRUE = @AMDEP_TRUE@ AMTAR = @AMTAR@ AUTOCONF = @AUTOCONF@ AUTOHEADER = @AUTOHEADER@ AUTOMAKE = @AUTOMAKE@ AWK = @AWK@ CC = @CC@ CCDEPMODE = @CCDEPMODE@ CFLAGS = @CFLAGS@ CPP = @CPP@ CPPFLAGS = @CPPFLAGS@ CYGPATH_W = @CYGPATH_W@ DEFS = @DEFS@ DEPDIR = @DEPDIR@ ECHO_C = @ECHO_C@ ECHO_N = @ECHO_N@ ECHO_T = @ECHO_T@ EGREP = @EGREP@ EXEEXT = @EXEEXT@ INSTALL_DATA = @INSTALL_DATA@ INSTALL_PROGRAM = @INSTALL_PROGRAM@ INSTALL_SCRIPT = @INSTALL_SCRIPT@ INSTALL_STRIP_PROGRAM = @INSTALL_STRIP_PROGRAM@ LDFLAGS = @LDFLAGS@ LIBOBJS = @LIBOBJS@ LIBS = @LIBS@ LTLIBOBJS = @LTLIBOBJS@ MAKEINFO = @MAKEINFO@ OBJEXT = @OBJEXT@ PACKAGE = @PACKAGE@ PACKAGE_BUGREPORT = @PACKAGE_BUGREPORT@ PACKAGE_NAME = @PACKAGE_NAME@ PACKAGE_STRING = @PACKAGE_STRING@ PACKAGE_TARNAME = @PACKAGE_TARNAME@ PACKAGE_VERSION = @PACKAGE_VERSION@ PATH_SEPARATOR = @PATH_SEPARATOR@ SET_MAKE = @SET_MAKE@ SHELL = @SHELL@ STRIP = @STRIP@ VERSION = @VERSION@ ac_ct_CC = @ac_ct_CC@ ac_ct_STRIP = @ac_ct_STRIP@ am__fastdepCC_FALSE = @am__fastdepCC_FALSE@ am__fastdepCC_TRUE = @am__fastdepCC_TRUE@ am__include = @am__include@ am__quote = @am__quote@ bindir = @bindir@ build_alias = @build_alias@ datadir = @datadir@ exec_prefix = @exec_prefix@ host_alias = @host_alias@ includedir = @includedir@ infodir = @infodir@ install_sh = @install_sh@ libdir = @libdir@ libexecdir = @libexecdir@ localstatedir = @localstatedir@ mandir = @mandir@ oldincludedir = @oldincludedir@ prefix = @prefix@ program_transform_name = @program_transform_name@ sbindir = @sbindir@ sharedstatedir = @sharedstatedir@ sysconfdir = @sysconfdir@ target_alias = @target_alias@ SUBDIRS = . src doc man EXTRA_DIST = BUGS TODO subdir = .

Changed the file layout, to sepparte man pages from htlm pages. YagiUda-1.1.18, 29/10/2000 Generate output for gnuplot on a linear scale in addition to a log scale Changed the names of a few files, to be more explicit Cleaned up a lot of code, so gcc generates far less warnings. Corrected a bug in first.c so that it works okay for non-uniform diamater elements. included stdlib.h if possible in all files, to remove a linux bug Correct a few spelling errors in first and input. Changed input so it can handle antennas with different diameter elements. yagiuda-1.19.orig/TODO0000644000175000017500000000243707176260023013017 0ustar pg4ipg4iHere is a list of things I consider need improving in the programs, as of version 1.08. 1) Some graphical interface would be nice. I personally am not much into writing X or Windows software, but realise that it would be better if the program run under one or the other (both??). It would be nice to move and adjust elements with a mouse, and the program recalculate performance. 2) The functions that do the LU decomposition and back substitution are a bit wasteful of time and storage space, since they are basically real routines, being pushed to do complex maths. Hence rewriting them to handle complex maths would be very nice. 3) The optimisation routine adjusts elements randomly. Whist I feel this is useful, since you could otherwise reach a local optimum in performance, but really not have a global optimum, its rather slow. The option of a more intelligent optimisation algorithm (stepest decent etc) would be nice. The GA is one answer to this. 4) Identify and remove all unknown bugs! 5) Optimise parameters og the genetic algorithm (GA). If anyone intends to re-write some of the code, please e-mail me and tell me what you are doing. Then I will be able to keep a track of what people are doing. It might save duplication. If you then send me updated files, I'll put on an ftp site. yagiuda-1.19.orig/aclocal.m40000644000175000017500000007041210264170220014154 0ustar pg4ipg4i# generated automatically by aclocal 1.7 -*- Autoconf -*- # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002 # Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. # Do all the work for Automake. -*- Autoconf -*- # This macro actually does too much some checks are only needed if # your package does certain things.

NAME

     yagi - Yagi-Uda project antenna current calculator

SYNOPSIS

     yagi [ - dhps ] filename

DESCRIPTION

     The program yagi is one of a number of  executable  programs
     that  forms part of a set of programs, collectively known as
     the Yagi-Uda project , which were designed for analysis  and
     optimisation  of  Yagi-Uda  antennas.  yagi  calculates  the
     currents at the centre of each element at one or  more  fre-
     quencies, as specified in the input file.

     -d   Display element currents. When this option is  used,  a
          bar  graph  with  up to 70 stars (*) is used to display
          the absolute magnitude of  the  element  currents.  The
          element  with  the greatest element current has 70 *'s,
          all others have a corresponding smaller number, depend-
          ing on the their relative current. The element current,
          normallised to the maximum, is also shown as a 4  digit
          floating point number.

     -h   Print a help message.

     -p   Print the Z matrix.  The  Z  matrix  is  the  impedance
          matrix,  showing  the self impedance of the elements on
          the diagonal and the mutual impedance off the diagonal.

     -s   Suppress all diagnostic output. By default, the program
          print the percentage of the job completed.

      filename
          is the name of the file containing the antenna descrip-
          tion.  It  is  expected  to  be  in a format created by
          either input or first  -  two  other  programs  in  the
          Yagi-Uda  project.  This  is  an  ASCII  text file. The
          antenna currents are written  to  a  file  filename.out
          which  is  a binary file. It is not intended to be read
          by humans.

Limitations

     I'm not aware of any limitations, apart from that filenames,
     including full path, can't exceed 90 characters.

DESCRIPTION

     The program first is one of a number of executable  programs
     that  forms part of a set of programs, collectively known as
     the Yagi-Uda project , which were designed for analysis  and
     optimisation  of  Yagi-Uda antennas. first is used to define
     an antenna quickly, if you are not interested in analysing a
     specific design (in which case use input ) but need to get a
     design that is half-way reasonable so that it may be  optim-
     ised.  It  is much faster in use (since its not interactive)
     than input The design methodology that first  is  the  DL6WU
     antenna  designs,  which  are valid for 10 or more elements,
     although first will calculate for any  number  of  elements.
     DL6WU  reccomends  a folded dipole, but the designs here are
     for a simple dipole, since I don't yet know how to calculate
     the self and mutual impedances of folded dipoles.

LIMITATIONS

     Filenames, including full path, can't exceed 90 characters.

     Does not take into account the variation of impedance  of  a
     dipole with change in wavelength/diameter of elements.

DESCRIPTION

     The program input is one of a number of executable  programs
     that  forms part of a set of programs, collectively known as
     the Yagi-Uda project , which were designed for analysis  and
     optimisation  of  Yagi-Uda antennas. input is an interactive
     program, that asks the user for  information  about  a  Yagi
     design,  such  as position of elements, spacing between ele-
     ments, frequency span of interest and a filename to save the
     data  to.   input then writes this information into an ASCII
     file, which can be read by yagi  or  optimise  The  file  is
     ASCII  and  it's  format  is easily understood by inspection
     (there are comments printed in it), so it can  if  necessary
     be edited manually.

     After running input and specifying a filename  (for  example
     144e10)  you  should  then  type yagi 144e10 and then output
     144e10 and optionally optimise 144e10

NAME

SYNOPSIS

     output [ - cehps ] [ -EE_max ] [ -HHmax ] [  -rminimum  ]  [
     -Rmaximum ] [ -ZZo ]

     filename

DESCRIPTION

     The program output is one of a number of executable programs
     that  forms part of a set of programs, collectively known as
     the Yagi-Uda project , which were designed for analysis  and
     optimisation  of  Yagi-Uda  antennas.  output calculates the
     gain, FB ratio, input impedance etc etc of an  antenna  that
     was  described by the program input or first and has had the
     element currents calculated with the program yagi  The  data
     about  the forward gain, VSWR, FB ratio, input impedance etc
     is written to a file filename.dat Angular data,  giving  the
     variation  of  gain  with  theta  and phi is put into a file
     filename.gai
     Sometimes the program fails to find the  3dB  bandwidths  in
     the  E  and  H  planes, and bombs out with a 'zbrent' error.
     This can occur if:
     (1) The antenna has an almost isotropic  pattern,  in  which
     case its never 3dB down, so the 3dB point is undefined.
     (2) The 3dB point is outside the assumed angular range.  You
     then have to either:
     (a) Calculate with the -e option, which  avoids  calculation
     of the 3dB E-plane beamwidth or
     (b) Do (a) above, then  find  approximately  where  the  3dB
     point  is  (from the .gai file -see later), then set options
     -E and -H so the program calculates them properly.

     The DOS .EXE files as distributed require a 387 maths copro-
     cessor  to  be  present  and will not run without it. A 486,
     Pentium, and I assume later processors of this  series  will
     run  it  without  any  extra  hardware. The DOS files are no
     longer being maintained, so are out of sync with the  latest
     source.

OPTIONS

     -c   Calculate the maximum level of any sidelobe - not  just
          the  rear  on as the FB ratio tells us. If the sidelobe
          and FB ratio are equal, it means the  biggest  sidelobe
          is  the  rear  one. If the Sidelobe is less than the FB
          ratio, then another lobe is more significant.  Look  in
          the  '.gai'  file  (see below) to see where it is. This
          option slows the program quite a bit.

     -e   Suppress calculation of the 3dB E-plane bandwidth. This
          is  sometimes  necessary  if the programme is unable to
          find the 3 dB beamwidth, to prevent an error occuring.

     -h   Suppress calculation of the 3dB H-plane bandwidth. This
          is  sometimes  necessary  if the programme is unable to
          find the 3 dB beamwidth, to prevent an error occuring.

     -p   Put data into a file  filename.freq  for  reading  into
          gnuplot, and a commmand file filename.gc for gnuplot to
          use.  (run   'output   -p   filename'   then   'gnuplot
          filename.gc' )

     -s   Suppress all diagnostic output. By default, the program
          print the percentage of the job completed.

     -EE_max
          When the program computes the E-plane 3dB beamwidth, it
          assumes  the  antenna  pattern is 3dB down somewhere in
          the range 90 to Emax, where E_max  is  by  default  179
          degrees.  This  can fail if it is never 3dB down in the
          range, or if it happened to go 3dB down in two or  more
          points.  You  can  change  E_max,  if  you need to, but
          rarely if every should  need  to.  I've  never  seen  a
          failure here, but are guarding against one. If you dont
          want the pattern, use  the  -e  option  instead,  which
          skips it. See also '-H' below.

     -HH_max
          When the program computes the H-plane 3dB beamwidth, it
          assumes  the  antenna  pattern is 3dB down somewhere in
          the range 0 to Hmax,  where  H_max  is  by  defualt  60
          degrees.  This  can fail if it is never 3dB down in the
          range, or if it happended to go 3dB down in two or more
          points.  Also,  if it goes more than 3dB down, but that
          starts to come up again. You can change H_max,  if  you
          need to, as failures do occasionally occur. If you dont
          want the pattern use -h option instead, which will skip
          it.
          An obvious example of an antenna where  you  cant  find
          the  3dB  bandwidth for the H-plane is the 1ele dipole.
          The radiation is symmetrical about  its  axis,  so  the
          level  is  the same everywhere in the H plane. The pro-
          gram automatically avoids calculating it for  a  1  ele
          beam.


     -ZZo Zo is the characteristic impedance used when  calculat-
          ing  the  VSWR.  By  default  it's  50 Ohms, but can be
          changed to any real, positive value.


      filename
          is  the  name  of  the  file  containing  the   antenna
          description.  It  is expected to be in a format created
          by input or first - two other programs in the  Yagi-Uda
          project.  The  is  also expected to exist a binary file
          filename.out created by typing yagi filename

Limitations

     I'm not aware of any limitations, apart from that filenames,
     including full path, can't exceed 90 characters.

FILES

     filename        ASCII file with antenna description.
     filename.out    Binary data file, created by yagi.
     filename.dat    ASCII file with gain, FB ratio etc.

BUGS

     tend  actually to be fixed if they can be isolated, so it is
     in your interest to report them in such a way that they  can
     be  easily  reproduced.  The program gives errors if element
     lengths are well away from a half-wave (by a factor  of  ~3)
     due  to  a breakdown in the equations.  If the input file is
     edited  manually  and  done  incorrectly,   there   can   be
     unpredictable results.

DESCRIPTION

     The program optimise is one of a number of  executable  pro-
     grams  that  forms  part  of a set of programs, collectively
     known as the Yagi-Uda project  ,  which  were  designed  for
     analysis  and  optimisation  of  Yagi-Uda antennas. optimise
     attempts to optimise the performance of a Yagi  antenna  for
     one  or  more parameters that are considered important, such
     as gain, F/B ratio, VSWR  etc.  It  does  this  by  randomly
     changing the lengths and positions, of one or more elements,
     then comparing the performance before and after the  change.
     Any   improvements   are   written  to  a  new  file  called
     filename.bes where filename  is  the  name  of  the  antenna
     description file created by input or first

     When Yagi's are designed on paper, or  using  this  program,
     its  possible  that they will be almost impossible to build,
     if their performance depends too critically  on  the  dimen-
     sions.  To  determine  if this is the case with a design, we
     run optimise with  just  the  options  't'  and  'T'.  These
     specify  the tolerance with which you can build the antenna,
     expressed as a standard  deviation  in  mm.  In  this  case,
     instead  of  trying to optimise a poor design, optimise will
     calculate the minimum gain, maximum  VSWR,  and  minimum  FB
     ratio  of  a  number of designs, all slightly different from
     the input file. 99.7% of the components lie within 3  SD  of
     the  mean, so if you think you can cut elements to with 1 mm
     99.7% of the time, specify t0.33. If you can put them in the
     boom to within 3 mm 99.7% of the time, specify T1.

     If while optimise is running using the methods that  require
     weights  to be attached to the gain, FB, SWR etc, it becomes
     apparent, the weights are not optimum, its possible to pause
     the  program  and  re-adjust the weights. If a file with the
     name of changes is created, the  program  will  pause,  then
     request new weights are entered at the keyboard.

AVAILABILITY

OPTIONS

     -d   Print the  default  values  of  all  the  configureable
          parameters  to  stdout.  Typing  this  option  with any
          option  that  changes  a  parameter  (see  below)  will
          display the new value of the parameter, rather than the
          default.

     -h   Print a help message.

     -v   Print verbose status information.

     -w   Instead of  optimising  at  one  fixed  frequency  (the
          design frequency), this directs the program to optimise
          at 3 separate frequencies (lowest, design and  highest)
          then  to  average  data at all 3. This option is better
          for wideband antenna. Note  that  the  input  impedance
          printed is at the design frequency, *not* averaged over
          3 frequencies. Averaging an  impedance,  is  likely  to
          give  a very misleading impression. The impedance aver-
          aged over 3 frequencies can be 50+i0 Ohms, even if  the
          VSWR  is  very poor over all 3 frequencies, as the fol-
          lowing 3 pieces of data show.
          Z=147 + j 300  SWR= 15.46:1
          Z=2   + j 100  SWR= 125:1
          Z=1   - j 400  SWR= 3250:1
          note in the above three cases, the average impedance is
          50 + j 0, but average SWR is 1130:1.

     -O   Over-optimisation allowed.   By  default,  the  program
          does not over-optimise a parameter. For example, an SWR
          of 1.01 is  usually  considered  good  enough  and  any
          change, as long as the SWR stayed good, typically below
          1.1:1, would be allowed,  even  if  the  SWR  rose.  By
          default,  FB's  of 27 dB, VSWR's of 1.1 are acceptable.
          However, by using the -O option,  you  can  insist  the
          program always improves things, no matter how good they
          are.

          centage by setting boom_extension to whatever you wish.
          -b30  will limit the boom to no more than 30% more than
          the original length.

     -ccleanliness_of_pattern
          Specify the number of dB down on the peak gain  to  aim
          to  get  the  pattern. Any antenna pattern cleaner than
          this will not effect the fitness, nor will it  be  con-
          sidered  any  better when comparing to antenna designs.
          20 dB seems reasonable, so the default is 20, but  this
          may  of  course  change if it's deceided too. Check the
          source code to be certain (see  REASONABLE_SIDELOBE  in
          yagi.h).

     -eelements
          is an integer which specifies the type of elements that
          are changed in the optimisation cycle.  Possible values
          are:
           1 - alter only the driven element(s) length (useful to
           bring to resonance)
           2 - alter only  the  driven  element  position.  Don't
           change its length.
           4 - alter only the reflector length. The  position  is
           always at x=0.
           8 - alter only  the  director  lengths.  Don't  change
           positions.
           16 - alter only the director positions.  Don't  change
           lengths.
           32 - randomly adjust one element  length,  then  makes
           all other the same. Don't change the positions.
           64 - apply a linear taper to the lengths.
           128 - Set the driven element to a resonate length.  It
           may/may-not  be altered after the first run, depending
           on the whether or not '1' is  invoked  too.  Eg  -e128
           will  make it resonate and keep it there forever. How-
           ever '-e129' will bring to resonance,  then  alter  to
           maximuse performance.
         The elements altered is made from a logical AND  of  the
         above,  so  for  example to alter everything, except the
         driven element length, use -e30, since 2+4+8+16=30.  The
         default is equivalent to -e31 , which changes everything
         possible.  Note  the  reflector  position   is   *never*
         changed. It's always at x=0.

          greater than FBratio dB to be equal to FBratio dB. This
          avoids optimising to a very high  FB  ratio,  which  is
          impracticable,  as  the  bandwidth  over  which this FB
          ratio will be maintained is very small  and  mechanical
          considerations  will  prevent  you from constructing it
          with such a high FB  ratio  anyway.  If  this  was  not
          prevented, you might just happen to get an antenna with
          100 dB FB ratio,  but  poor  gain  and  swr.  Since  by
          default  all  parameters must improve, the optimisation
          routine will most likely never being able to improve on
          the  100  dB  FB  ratio, so no improvement will result.
          Most people would prefer to get a few extra dB of gain,
          even if the FB ratio dropped to 30 dB.

     -gGA_optimisation_method
          Use a genetic algorithm. With  the  genetic  algorithm,
          the  program  does not take any account any of the ini-
          tial lengths/positions of  elements  specified  in  the
          input file. Rather it works by initialising a number of
          different antenna, then computing a 'fitness' value for
          each.   The  fitness  value can depend on the gain, FB,
          real part of the input impedance, reactive part of  the
          input  impedance,  VSWR  or the level of the sidelobes.
          The integer after the g tells  the  optimiser  what  to
          consider.  -g1  Use gain
          -g2  Use FB
          -g4  Use R
          -g8  Use X
          -g16 Use the SWR
          -g32 Use the level of the sidelobes.

          You can use a logical AND of these, so for example -g49
          will  use a genetic algorithm, optimising for gain, swr
          and sidelobe level,  since  1(gain)+16(SWR)+32(sidelobe
          level)=49.

     -lpercent
          is a parameter (floating point number) which  specifies
          the  maximum  percentage  change  in  the  positions or
          lengths of an elements at each iteration. If the option
          is  not  used, it will be set internally at 10% for the
          first 25% of the iterations, 1% for the next 25%,  0.1%
          for  the  third 25% of the iterations and 0.01% for the
          last 25% of the iterations. If set to a positive number
          x  (eg optimise -l 0.3 145e10) then the percentage will
          be set at x% for 25% of iterations, x/10 for the   next
          25%, x/100 for the next 25 and x/1000 for the last 25%.
          If set to a negative number  y  (eg  optimise  -l  -0.5
          145e10)  then  the  paramters will stay fixed at y% (in
          this example 0.5%) all the time.

     -mmin_offset-from_peak
          Sets the minimum angle in degrees offset from  theta=90
          degrees,  where  the side lobes start and the main lobe
          finishes. The higher the gain, the  smaller  it  should
          be.  It  is  set  internally  if not set on the command
          line.

     -ooptimisation_criteria
           1 -  Assume better if the gain has increased.
           2 -  Assume better if the  front  to  back  ratio  has
           improved.
           4 -  Assume better if  the  real  part  of  the  input
           impedance  is closer to the value that the program was
           compiled for, or set using the '-Z' option. This  will
           usually  be  50  Ohms, but you may wish to set this to
           12.5 Ohms if you use a 4:1 balun.  Generally  you  can
           get  higher  gain  from  a Yagi if you allow the input
           impedance to fall, but of course  feeding  it  becomes
           more difficult.
           8 -  Assume better if the magnitude  of  the  reactive
           component  of  the  input  impedance is lower (ie. the
           antenna is nearer resonance).
           16 - Assume better if the VSWR is lower.
           32 - Assume better if the level of  all  sidelobes  is
           lower.
         The optimisation_criteria may be formed from  a  logical
         AND  of these numbers, so for example choosing -o19 will
         only consider a revised antenna better than  the  previ-
         ous,  if the SWR, gain and F/B ratio have all simultane-
         ously improved.

         Clearly an antenna which originally had 12 dB  gain  and
         1.01:1  VSWR  but  then  changes  to 20 dB gain @ 1.02:1
         VSWR, would to most people be better,  even  though  the
         VSWR  has increased. By default, optimise only optimises
         to sensible maximums, so to  not  let  the  optimisation
         stall  prematurely.  By  running  optimise with no argu-
         ments, the program will list the limits  of  acceptabil-
         ity.  These might be typically F/B ratio > 27 dB, VSWR <
         1.1:1, magnitude of input reactance less than 5 Ohms and
         the  real  part  of the input impedance within 5 Ohms of
         Zo. Choosing -o19 (1+2+16=19)  will  optimise  for  gain
         (since G=1), FB (since FB=2) and SWR (Since SWR=16), but
         would consider a higher gain and FB ratio antenna better
         than a previous one, even if the SWR rose, as long as it
         stayed below 1.1:1 (or as was set  during  compilation).
         The default behaviour (no options) is equivalent to -o37
         which optimiseas for gain(1), the real part of the input
         impedance(4)  and  sidelobes(32) but this may be changed
         at any time, so type optimise -d to  check  the  current
         settings.  If  you  insist on the program optimisang for
         the very best of all selected  parameters,  use  the  -O
         option  too, but be warned the optimisation will probely
         stick once it gets one parameter really good.

     -ppopulation
          This determines the initial population used   with  the
          genetic algorithm.

     -rresistance
          When optimising an antenna, consider any  input  resis-
          tance  closer  to  Zo (usually 50 Ohms) than resistance
          Ohms to be acceptable. This  avoids  optimising  to  an
          input  resistance too close to Zo, which is impractica-
          ble, as the bandwidth over which the  input  resistance
          could  be  maintained is very small and mechanical con-
          siderations will  prevent  you  from  constructing  the
          antenna  with  such  an ideal input resistance. If this
          was not prevented, you might  just  happen  to  get  an
          antenna with an input resistance of 50.000001 Ohms, but
          poor gain, FB and possibly even  a  poor  swr,  if  the
          antenna  is  well away from resonance. Since by default
          all parameters must improve, the  optimisation  routine
          will get most likely never being able to improve on the
          antenna, whereas we might be happier with a few more dB
          gain,  if  the  input  resistance went to 50.1 Ohms. It
          should be noted that the default  optimisation  routine
          never  uses  the input resistance directly (only VSWR),
          so this option cant be used without the '-o' option  to
          optimise  for  other than the default parameters (gain,
          VSWR and FB ratio).

     -sswr
          When optimising an antenna, consider any SWR less  than
          swr to be equal to swr This avoids optimising to a very
          low swr, which is impracticable, as the bandwidth  over
          which  such a low swr could be maintained would be very
          small and mechanical considerations  will  prevent  you
          from  constructing  such  an antenna anyway. If this is
          was not prevented, you might  just  happen  to  get  an
          antenna with an swr of 1.000000000001:1, but poor gain,
          FB ratio. Since by default all parameters must improve,
          the  optimisation  routine will most likely never being
          able to improve on the antenna, even though in practice
          you would like to get a few extra dB of gain if the SWR
          would rise to 1.02:1. The default was equivalent  to  -
          s1.1  but run optimise -d to display this and any other
          defaults.

     -tlength_tolerance
          length_tolerance is the standard deviation in mm of the
          accuracy  with  which you can cut elements. Since 99.7%
          of elements will be with 3 standard deviations  of  the
          mean length (stats theory says this), set -t0.2 if vir-
          tually  all  (well  99.7%)  of  elements   are   within
          3x0.2=0.6  mm of the correct length. This option *must*
          be used with the '-T'  option and can't  be  used  with
          any other options apart from

     -xreactance
          When optimising an antenna, consider  any  input  reac-
          tance  of  less  than  reactance  to be reactance. This
          avoids over optimising the reactance, at the expense of
          something else.

     -Aauto_gain
          When the auto_gain option is used. the program  maximes
          the  gain of the antenna (ignoring all other parameters
          such as SWR, FB ratio etc) by adjusting the length (not
          position)  of  one element only. -A-1 will maximuse the
          gain, by adjusting the length  of  the  reflector,  -A0
          will  maximise  the gain by adjusting the length of the
          driven element. Its generally *not* a good idea to max-
          imise the gain by adjusting the driven element, but the
          program lets you do it, but using the option -A0. Using
          -A1  will  maximise gain by adjusting the length of the
          first director, -A2 the second director and so  on,  up
          to the last director. You must check carefully that the
          input impedance in particular does not  fall  to  silly
          values if you use this option. On a yagi with many ele-
          ments (> 10 or so), you can pretty safely maximise  the
          8th  or  more  director, but doing it on the reflector,
          driven element or early directors often leads to  silly
          input  impedances - so beware! Note, no matter how many
          iterations you  specify,  this  process  is  only  done
          once.Its  unlikely  you  will  be  able to do it again,
          without things going out of hand, but if  you  must  do
          it, you must re-run 'optimise' again.

     -Ccurrents_similar
          If this option is used, where  currents_similar  is  an
          integer,  the program looks to make the currents in the
          last currents_similar elements as similar as  possible.
          It computes the sum of the squares of the deviations of
          the absolute values of the element  currents  from  the
          mean.  If  this  falls, and the criteria specified with
          the -W option is also satisfied, the  antenna  is  con-
          sidered  better. If currents_similar is three less than
          the number of directors, it tries to make the  currents
          in  the the directors (but ignoringing the first 3) all
          similar. If currents_similar is equal to the number  of
          directors,  it  tries  to  make  all the directors have
          similar currents. If currents_similar is one more  than
          the  number  of  directors,  it  tries  to make all the
          directors and the reflector have similar  currents.  If
          currents_similar  is  equal to the total number of ele-
          ments, then it fails with an error message.

     -Fweight_FB
          is the floating point number (default  1.0)  specifying
          the  weight  to  attach  to the FB ratio of the antenna
          when using the '-W' option, which calculates a  fitness
          for  the  antenna  based on one or more parameters (FB,
          gain, input resistance, input reactance, SWR,  cleanli-
          ness of antenna pattern). The '-F' option is similar to
          the options -G, -P, -R, -S, -X (which  specify  weights
          for  gain,  pattern  cleanliness, input resistance, SWR
          and input reactance). When  using  the  -W  option  the
          exact  algorithm used to compute the fitness (and hence
          the effect of this parameter) is best checked by  look-
          ing  at  the  source  code (see perform.c). This is one
          area           of           constant            program
          improvement/changes/development,  so  its  difficult to
          say exactly the  effect  the  parameter  has.  However,
          increasing the weight of a parameter (using the -F, -G,
          -R, -S or -X options) will make  the associated parame-
          ter  have  a  greater  effect  on the fitness. However,
          unless you optimise for a high FB  ratio  with  the  -W
          option, then setting the -F option will have no effect.
          For example, setting the options -F2.5 -W1  is  a  com-
          plete waste of time. There you have used the -W1 option
          to optimise only for gain (see -W option section of man
          page)  but have changed the weight of the FB ratio from
          its default 1.0 to 2.5. If you are not  optimising  for
          FB ratio, the weight you attach to it is irrelavent.

     -Gweight_gain
          is the floating point number (default  1.0)  specifying
          the  weight  to  attach to the gain of the antenna when
          using the '-W' option, which calculates a  fitness  for
          the  antenna based on one or more parameters (FB, gain,
          input resistance, input reactance, SWR, cleanliness  of
          antenna  pattern).  The  '-G'  option is similar to the
          options -F, -P, -R, -S, -X (which specify  weights  for
          FB  ratio,  pattern  cleanliness, input resistance, SWR
          and input reactance). When  using  the  -W  option  the
          exact  algorithm used to compute the fitness (and hence
          the effect of this parameter) is best checked by  look-
          ing  at  the  source  code (see perform.c). This is one
          area           of           constant            program
          improvement/changes/development,  so  its  difficult to
          say exactly the  effect  the  parameter  has.  However,
          increasing the weight of a parameter (using the -F, -G,
          -R, -S or -X options) will make  the associated parame-
          ter  have  a  greater  effect  on the fitness. However,
          unless you optimise for gain with the -W  option,  then
          setting the -G option will have no effect. For example,
          setting the options -G2.5 -W2 is a  complete  waste  of
          time.  There  you  have used the -W2 option to optimise
          only for FB ratio (see -W option section of  man  page)
          but  have  changed  the  weight  of  the  gain from its
          default 1.0 to 2.5. If you are not optimising for gain,
          the weight you attach to it is irrelavent.

     -Kkeep_for_tries
          keep_for_tries is the number of tries for the  optimise
          to persist using the original data file as the starting
          point for optimisation. By default it is 1, which means
          the  program immediately looks from a new position once
          a better one is found. It  is  theeoretically  possible
          that  this might result in a quick, but poor local max-
          imum. If however, keep_for_tries is 1000, it will  stay
          at  a  position  for  1000 iterations after finding the
          last best result, before considering this to be a  glo-
          bal  optimum.  Then  it starts for the new position. In
          practice, I have found  this  option  to  make  matters
          worst  in  most cases. It was added to avoid the local-
          minimum problem, but it appears the  optimisation  sur-
          face  is  pretty  smooth, so it just slows the program,
          without gaining much. Anyway, it can stay as an option,
          but  check  the  results  with/without carefully before
          using extensively.

     -Ppattern_cleanlyiness
          is the floating point number (default  1.0)  specifying
          the  weight  to  attach to the cleanness of the antenna
          pattern when using the '-W' option, which calculates  a
          fitness for the antenna based on one or more parameters
          (FB, gain,  input  resistance,  input  reactance,  SWR,
          cleanliness  of  antenna  pattern).  The '-P' option is
          similar to the  options  -F,  -G,  -R,  -S,  -X  (which
          specify  weights  for FB ratio, gain, input resistance,
          SWR and input reactance). When using the -W option  the
          exact  algorithm used to compute the fitness (and hence
          the effect of this parameter) is best checked by  look-
          ing  at  the  source  code (see perform.c). This is one
          area           of           constant            program
          improvement/changes/development,  so  its  difficult to
          say exactly the  effect  the  parameter  has.  However,
          increasing the weight of a parameter (using the -F, -G,
          -R, -S or -X options) will make  the associated parame-
          ter  have  a  greater  effect  on the fitness. However,
          unless you optimise for a clean  antenna  pattern  with
          the  -W option, then setting the -P option will have no
          effect. For example, setting the options -P2.5 -W1 is a
          complete  waste  of  time.  There you have used the -W1
          option to optimise only for gain (see -W option section
          of man page) but have changed the weight of the pattern
          cleanliness from its default 1.0 to 2.5. If you are not
          optimising  for  a  clean radiation pattern, the weight
          you attach to it is irrelavent.  With appropiate use of
          the  -W  option (eg -W49 for gain, SWR and a clean pat-
          tern), the computer program finds the level of the most
          significant  sidelobe,  wherever  it may be outside the
          main bean. It then optimises to  reduce  this.  The  -P
          option tells it how much weight to put on reducing this
          sidelobe.

     -Rweight_resistance
          is the floating point number (default  1.0)  specifying
          the  weight  to attach to the obtaining an input resis-
          tance close to Zo on the antenna when  using  the  '-W'
          option,  which  calculates  a  fitness  for the antenna
          based on one or more parameters (FB, gain, input resis-
          tance,  input  reactance,  SWR,  cleanliness of antenna
          pattern). The '-R' option is similar to the options -F,
          -G,  -P,  -S,  -X  (which specify weights for FB, gain,
          pattern cleanliness, SWR  and  input  reactance).  When
          using the -W option the exact algorithm used to compute
          the fitness (and hence the effect of this parameter) is
          best  checked  by  looking  at  the  source  code  (see
          perform.c).  This  is  one  area  of  constant  program
          improvement/changes/development,  so  its  difficult to
          say exactly the  effect  the  parameter  has.  However,
          increasing the weight of a parameter (using the -F, -G,
          -R, -S or -X options) will make  the associated parame-
          ter  have  a  greater  effect  on the fitness. However,
          unless you optimise for an an input resistance close to
          Zo, with the -W option, then setting the -R option will
          have no effect. For example, setting the options  -R2.5
          -W1  is  a  complete waste of time. There you have used
          the -W1 option to optimise only for gain (see -W option
          section of man page) but have changed the weight of the
          resistance from its default 1.0 to 2.5. If you are  not
          optimising  for  an  input  resistance close to Zo, the
          weight you attach to it is irrelavent.

     -Sweight_swr
          is the floating point number (default  1.0)  specifying
          the  weight  to  attach  to the SWR of the antenna when
          using the '-W' option, which calculates a  fitness  for
          the  antenna based on one or more parameters (FB, gain,
          input resistance, input reactance, SWR, cleanliness  of
          antenna  pattern).  The  '-S'  option is similar to the
          options -F, -G, -P, -R, -X (which specify  weights  for
          FB,  gain,  pattern  cleanliness,  input resistance and
          input reactance). When using the -W  option  the  exact
          algorithm  used  to  compute the fitness (and hence the
          effect of this parameter) is best checked by looking at
          the  source  code  (see perform.c). This is one area of
          constant  program  improvement/changes/development,  so
          its  difficult  to say exactly the effect the parameter
          has. However, increasing  the  weight  of  a  parameter
          (using the -F, -G, -R, -S or -X options) will make  the
          associated parameter have a greater effect on the  fit-
          ness.  However, unless you optimise for SWR with the -W
          option, then setting the -S option will have no effect.
          For  example,  setting  the options -S2.5 -W1 is a com-
          plete waste of time. There you have used the -W1 option
          to optimise only for gain (see -W option section of man
          page) but have changed the weight of the SWR  from  its
          default  1.0 to 2.5. If you are not optimising for SWR,
          the weight you attach to it is irrelavent.

     -Tposition_tolerance
          position_tolerance is the standard deviation in  mm  of
          the  accuracy  with  which  you can cut elements. Since
          99.7% of elements will be with 3 standard deviations of
          the  correct position (stats theory says this), set -T2
          if virtually all (well 99.7%) of  elements  are  within
          3x2=6  mm of the correct position.This option *must* be
          used with the '-t'  option and can't be used  with  any
          other options apart from

     -WWeighted_algorithm
          Try to get an antenna which is better  according  to  a
          weighted combination of parameters, rather than require
          them all to improve. The integer specifies what to con-
          sider in the weighted parameters.
          W1 Gain.
          W2 FB
          W4 R
          W8 X
          W16 SWR
          W32 SIDE_LOBE
          You can logically AND these together,  so  for  example
          -W3  will optimise using a weighted combination of gain
          and FB. -W49, will use a weighted combination of  gain,
          swr and sidelobe leve, since 32+16+1=49.

     -Xweight_reactance
          is the floating point number (default  1.0)  specifying
          the weight to attach to achieving a low input reactance
          on the antenna when using the '-W' option, which calcu-
          lates  a  fitness  for the antenna based on one or more
          parameters (FB, gain,  input  resistance,  input  reac-
          tance,  SWR,  cleanliness of antenna pattern). The '-X'
          option is similar to the options -F, G, -P, -R  and  -S
          (which  specify  weights  for  FB  ratio, gain, pattern
          cleanliness, input resistance, and SWR). When using the
          -W  option the exact algorithm used to compute the fit-
          ness (and hence the effect of this parameter)  is  best
          checked  by looking at the source code (see perform.c).
          This    is    one    area    of    constant     program
          improvement/changes/development,  so  its  difficult to
          say exactly the  effect  the  parameter  has.  However,
          increasing the weight of a parameter (using the -F, -G,
          -R, -S or -X options) will make  the associated parame-
          ter  have  a  greater  effect  on the fitness. However,
          unless you optimise for a low input reactance with  the
          -W  option,  then  setting  the  -X option will have no
          effect. For example, setting the options -X2.5 -W1 is a
          complete  waste  of  time.  There you have used the -W1
          option to optimise only for gain (see -W option section
          of man page) but have changed the weight of the reacti-
          ance from its default  1.0  to  2.5.  If  you  are  not
          optimising  for  a  low input reactance, the weight you
          attach to it is irrelavent.

     -ZZo
          Zo is the characteristic impedance used when evaluating
          the VSWR, reflection coefficient and other similar cal-
          culations. The optimiser usually  tries  to  bring  the
          input impedance of the antenna to this value. It is set
          by default to 50 Ohms, so the default is equivalent  to
          -Z50 but may be set to any positive number. Set to 12.5
          Ohms if you are going to feed the antenna  with  a  4:1
          balun.  Generally  speaking,  the gain of a Yagi can be
          higher for low input impedances,  but  of  course  such
          antennas are more difficult to feed.

     filename
          This is the name of the  file  containing  the  antenna
          description.  It  is expected to be in a format created
          by either input or first - two other  programs  in  the
          Yagi-Uda project. This is an ASCII text file.

     iterations
          is an integer specifying the number of  iterations  for
          the  optimiser  to  perform  to  try  to  get  the best
          antenna. Time will limit the number  you  choose.  1000
          iterations of a 1ele yagi takes about 5 seconds, a 6ele
          approximately 60 seconds, an 11 element 350 seconds,  a
          20 element 1030 seconds, a 33ele 2440 seconds, a 50ele-
          ment 5400 seconds, 100ele 21320 seconds all on  an  old
          25MHz 486 PC with no external cache.  When using the -A
          option the iterations is automatically  set  internally
          so  only  one attempt is made.  When using the '-t' and
          '-T' options, iterations specifies the number of itera-
          tions  to  attempt to get a poorer design, to check the
          sensitivity of the design to small manufacturing toler-
          ances.

EXAMPLES

     Here are a number of examples of using optimise.

     1) optimise 5ele 1000

     Here the file 5ele will be optimised using the default  sys-
     tem for 1000 iterations. The default might typically require
     gain, FB and SWR to all improve, but this may be changed  at
     any  time.  In  any  case,  the  program  tells you what its
     optimising for. By default the program will only optimise to
     the  selected  parameters  are good, not over-optimising any
     one at the detrement of the others.

     2) optimise -b30 -f50 -s2 5ele 1000

     This is similar to above, but the boom  can  not  extend  by
     more  than 30% from its  original length, FB ratios above 50
     dB are considered acceptable, as are SWR's  less  than  2:1.
     The  optimised resultant antenna is likely to have better FB
     ratio, but poorer SWR than in (1) above.

     3) optimise -o1 5ele 1000

     This will simply optimise 5ele for maximum forward gain. The
     resultant  antenna may have a poor FB ratio and is likely to
     have an unacceptably low  input  impedance  and  hence  high
     VSWR. This is not a very sensible method of optimisation.

     4) optimise -W49 -l7 5ele 10000

     This will optimise the file 5ele using for 10000 iterations.
     It will require that the weighted performance of the antenna
     in three important parameters (gain, sidelobe level and SWR)
     improves  from one design to the next. One or two parameters
     can actually get worst from one design to the next, but  the
     weighted  performance  is  better. The positions of the ele-
     ments or lengths of elements will not change by more than 7%
     in each iteration.

     5) optimise -g -S30 -G50 -F20 -p1500 5ele 10000

     This will optimise the file 5ele using a genetic  algorithm.
     1500  antennas will be randomly designed. The performance of
     each of these will  measured  using  a  'fitness'  function,
     weighted  30%  to  SWR, 50% to gain and 20% to FB ratio. The
     probability of breading from a pair of antennas  is  propor-
     tional to the fitness function.

     6) optimise -w atv_antenna 10000

     This will optimise the file atv_antenna for a  best  average
     performance  over  a  wide band. The progrram calculates the
     gain, FB and SWR at  three  frequencies,  then  computes  an
     average  (mean)  performance of the antenna over the band. N
     iterations will take 3x as long to execute as  N  iterations
     on the same antenna without the '-w' option.

     7) optimise -t0.1 -T1  good_design 100

     This will take the file good_design and make  100  different
     antennas from it, to simulate the effects of building toler-
     ances. Each element is assumed to be cut so  that  the  mean
     error  of  all elements is 0 mm, but a standard deviation of
     0.1 mm, so 68.4% of element lengths are within 0.1 mm, 95.4%
     within  0.2  mm  and  99.7%  with in 0.3 mm. The accuracy of
     placing elements along the boom is much lower,  so  here  we
     have  specified  a standard deviation of 1.0 mm, so 68.6% of
     elements are placed within 1 mm  of  the  correct  position,
     95.4%  within 2 mm of the correct position etc.  The program
     will report the *worst* performances achieved. If  the  per-
     formance  dips  too mush, then you either need to build them
     better, or get a design that's less critical!

STOPPING

     Optimise will stop after the number of iterations  specified
     in  the  parameter  iterations.  It will also stop if a file
     stop exits  in  the  current  directory  of  the  executable
     optimise  This  file  can  of course only be created using a
     multi-tasking operating system such as  Unix.  It  is  *not*
     advisable  to stop the program by hitting the DEL key (Unix)
     or CONTROL-C (DOS), as one of the files may be open  at  the
     time, resulting in an empty file. Files are not open for any
     longer than necessary (they  are  closed  immediately  after
     writing  to  them),  so this is not a likely occurrence, but
     can still occur.

LIMITATIONS

     I'm not aware of any limitations, apart from that filenames,
     including full path, can't exceed 90 characters.

FILES

     filename           Antenna description, created by input or first.
     filename.up    Update file, listing achievements of optimise.
     filename.bes       Best file, containing the best design to date.
     changes         File that causes the program to pause to re-adjust weights.
     stop            File that stops optimisation process.

SEE ALSO

     first(1), input(1), output(1), yagi(1),  first(5),  input(5)
     output(5) and optimise(5).

PLATFORMS

     Both DOS and Unix versions have been built. The DOS  version
     as  distributed requires a 386 PC with a 387 maths coproces-
     sor.

     Although I have altered the source to make it more  compati-
     ble  with DOS (reduced file name lengths etc), my wish is to
     build a decent program, rather than fit the  program  to  an
     outdated  operating  system.  If there is a *good* reason to
     use code that is incompatible with DOS, this will be done.
     Since optimise takes  a while to optimise an  antenna  (I've
     optimised  one design for a week), it is obviously more sen-
     sible to build this program under a multi-tasking  operating
     system, as otherwise a PC can be tied up for days.

BUGS

     Bugs should be reported  to  david.kirkby@onetel.net.   Bugs
     tend  actually to be fixed if they can be isolated, so it is
     in your interest to report them in such a way that they  can
     be easily reproduced.

     The program will dump core (crash) if asked  to  optimise  a
     1ele  beam,  without  any arguments.  This is because a 1ele
     beam has no parasitic elements and by  default  the  program
     only changes parasitic elements.

     Some of the options are not  checked  for  sensible  values,
     although  most are now checked and report if they are out of
     range.

     If the user specifies very large manufacturing errors  using
     the  '-t'  and  '-T'  options,  its possible for elements to
     overlap or for element lengths to become negative. This will
     cause numerical errors. Any reasonable values will not cause
     this.


     On long Yagi's (50 elements) optimise can go a bit silly. It
     can  optimise  say  a 1296MHz Yagi to get 20 dB at 1296 MHz,
     but less than 0 dB at only 1 MHz away. Needs some thought!

     The level of the sidelobes is not computed with  the  GA  or
     some other optimisation types. This will be corrected later.

     All those I don't know about.

Introduction

The Yagi-Uda project is a set of programmes for designing, analysing and optimising Yagi-Uda antennas, with 2 or more elements, such as shown below.

The programmes were developed by Dr. David Kirkby (G8WRB) and run on unix systems. They have been successfully compiled on Solaris 8 (SPARC), Red Hat linux (release 6.1 on a PC) and FreeBSD on a PC. In each case the gcc C compiler (2.95.1 or 2.95.1) were used. There are some old 32-bit DOS executables, but they are no longer updated. There are no executables for any version of Microsoft Windows (Win 3.1, 95, 88, NT or 2000).

Several programmes are included:
 

  • first
  • input
  • yagi
  • output
  • optimise
  • dipole

    •  

     

    A few other programmes that were developed for test purposes are included, but there are not needed for normal use.

    Here are the old source files -  versions  1.15 1.16    1.17-

    Building the programmes

    Designing an antenna.

    Several stages are needed to design a Yagi-Uda  antenna using these tools

    1) What you do first depends on whether you have an antenna design you wish to analyse (like one from a book) or if you want to design one using the tools in the Yagi-Uda project.

    a) If you have an antenna you wish to analyse, use input to specify it in the form suitable for the programmes in the Yagi-Uda project.

    OR

    b) Assuming you don't know exactly what you wish to analyse, you can let the programme first design you an antenna. It wont be good, but it is sufficiently close to optimal that it can be optimised with optimise.

    2) Calculate the currents in the antenna, using the programme yagi

    3) Calculate the performance of the antenna using the programme output.

    4) Look at the files created by output to see how good the antenna is. A file filename.gc can be read into gnuplot.

    5) You may only want to do 1-4 above, but you will probably want to optimise the antenna, using optimise

.SH NAME yagi \- Yagi-Uda project antenna current calculator .SH SYNOPSIS .B yagi [ .B -\ dhps ] filename .SH DESCRIPTION The program .I yagi is one of a number of executable programs that forms part of a set of programs, collectively known as the .I Yagi-Uda project , which were designed for analysis and optimisation of Yagi-Uda antennas. .I yagi calculates the currents at the centre of each element at one or more frequencies, as specified in the input file. .SH AVAILABILITY .SH OPTIONS .TP .B \-d Display element currents. When this option is used, a bar graph with up to 70 stars (*) is used to display the absolute magnitude of the element currents. The element with the greatest element current has 70 *'s, all others have a corresponding smaller number, depending on the their relative current. The element current, normallised to the maximum, is also shown as a 4 digit floating point number. .TP .B \-h Print a help message. .TP .B \-p Print the Z matrix. The Z matrix is the impedance matrix, showing the self impedance of the elements on the diagonal and the mutual impedance off the diagonal. .TP .B \-s Suppress all diagnostic output. By default, the program print the percentage of the job completed. .TP .I \ filename is the name of the file containing the antenna description. It is expected to be in a format created by either .I input or .I first - two other programs in the .I Yagi-Uda project. This is an ASCII text file. The antenna currents are written to a file .I filename.out which is a binary file. It is not intended to be read by humans. .SH Limitations I'm not aware of any limitations, apart from that filenames, including full path, can't exceed 90 characters. .SH FILES filename.out Binary data file .br .SH "SEE ALSO" first(1), input(1), output(1), optimise(1), first(5), input(5), output(5) and optimise(5). .SH PLATFORMS Both DOS and Unix versions have been built. The DOS version as distributed requires a 386 PC with a 387 maths coprocessor. .SH BUGS Bugs should be reported to .BR david.kirkby@onetel.net . Bugs tend actually to be fixed if they can be isolated, so it is in your interest to report them in such a way that they can be easily reproduced. If the input file is edited manually and done incorrectly, there can be unpredictable results. .SH AUTHORS Dr. David Kirkby G8WRB (david.kirkby@onetel.net), with help with converting to DOS from Dr. Joe Mack NA3T (mack@fcrfv2.ncifcrf.gov). yagiuda-1.19.orig/man/man1/first.10000644000175000017500000000515510264163560015147 0ustar pg4ipg4i.TH FIRST 1 "Fri Dec 2 1994" "Version 1.10 " .de BP .sp .ns .ti -.2i \(** .. .SH NAME first \- Yagi-Uda project quick antenna builder .SH SYNOPSIS .B first filename elements f_min f_design f_max f_step diameter .SH DESCRIPTION The program .B first is one of a number of executable programs that forms part of a set of programs, collectively known as the .I Yagi-Uda project , which were designed for analysis and optimisation of Yagi-Uda antennas. .I first is used to define an antenna quickly, if you are not interested in analysing a specific design (in which case use .I input ) but need to get a design that is half-way reasonable so that it may be optimised. It is much faster in use (since its not interactive) than .I input The design methodology that .I first is the DL6WU antenna designs, which are valid for 10 or more elements, although .I first will calculate for any number of elements. DL6WU reccomends a folded dipole, but the designs here are for a simple dipole, since I don't yet know how to calculate the self and mutual impedances of folded dipoles. .LP .SH LIMITATIONS Filenames, including full path, can't exceed 90 characters. .PP Does not take into account the variation of impedance of a dipole with change in wavelength/diameter of elements. .SH FILES .nf filename Yagi description, created by first. filename.out Binary data file, created by yagi. filename.dat Performance of antenna, created by output. filename.gai Gain of antenna, created by output. .fi .br .br The DOS .EXE files as distributed require a 387 maths coprocessor to be present and will not run without it.

This can occur if: .br (1) The antenna has an almost isotropic pattern, in which case its never 3dB down, so the 3dB point is undefined. .br (2) The 3dB point is outside the assumed angular range. You then have to either: .br (a) Calculate with the -e option, which avoids calculation of the 3dB E-plane beamwidth or .br (b) Do (a) above, then find approximately where the 3dB point is (from the .gai file -see later), then set options -E and -H so the program calculates them properly. .LP .br The DOS .EXE files as distributed require a 387 maths coprocessor to be present and will not run without it. A 486, Pentium, and I assume later processors of this series will run it without any extra hardware. The DOS files are no longer being maintained, so are out of sync with the latest source. .SH OPTIONS .TP .B \-c Calculate the maximum level of any sidelobe - not just the rear on as the FB ratio tells us. If the sidelobe and FB ratio are equal, it means the biggest sidelobe is the rear one. If the Sidelobe is less than the FB ratio, then another lobe is more significant. Look in the '.gai' file (see below) to see where it is. This option slows the program quite a bit. .TP .B \-e Suppress calculation of the 3dB E-plane bandwidth. This is sometimes necessary if the programme is unable to find the 3 dB beamwidth, to prevent an error occuring. .TP .B \-h Suppress calculation of the 3dB H-plane bandwidth. This is sometimes necessary if the programme is unable to find the 3 dB beamwidth, to prevent an error occuring. .TP .B \-p Put data into a file filename.freq for reading into gnuplot, and a commmand file filename.gc for gnuplot to use. (run 'output -p filename' then 'gnuplot filename.gc' ) .TP .B \-s Suppress all diagnostic output. By default, the program print the percentage of the job completed. .TP .BI \-E E_max When the program computes the E-plane 3dB beamwidth, it assumes the antenna pattern is 3dB down somewhere in the range 90 to Emax, where E_max is by default 179 degrees. This can fail if it is never 3dB down in the range, or if it happened to go 3dB down in two or more points. You can change E_max, if you need to, but rarely if every should need to. I've never seen a failure here, but are guarding against one. If you dont want the pattern, use the -e option instead, which skips it. See also '-H' below. .TP .BI \-H H_max When the program computes the H-plane 3dB beamwidth, it assumes the antenna pattern is 3dB down somewhere in the range 0 to Hmax, where H_max is by defualt 60 degrees. This can fail if it is never 3dB down in the range, or if it happended to go 3dB down in two or more points. Also, if it goes more than 3dB down, but that starts to come up again. You can change H_max, if you need to, as failures do occasionally occur. If you dont want the pattern use -h option instead, which will skip it. .br An obvious example of an antenna where you cant find the 3dB bandwidth for the H-plane is the 1ele dipole. The radiation is symmetrical about its axis, so the level is the same everywhere in the H plane. The program automatically avoids calculating it for a 1 ele beam. .TP .BI \-Z Zo Zo is the characteristic impedance used when calculating the VSWR. By default it's 50 Ohms, but can be changed to any real, positive value. .TP .I \ filename is the name of the file containing the antenna description. It is expected to be in a format created by .I input or .I first - two other programs in the .I Yagi-Uda project. The is also expected to exist a binary file .I filename.out created by typing .I yagi filename .SH Limitations I'm not aware of any limitations, apart from that filenames, including full path, can't exceed 90 characters. .SH FILES .nf filename ASCII file with antenna description. filename.out Binary data file, created by yagi. filename.dat ASCII file with gain, FB ratio etc. filename.gai ASCII file with angular dependence of gain. .f .br .SH "SEE ALSO" first(1), input(1), yagi(1), optimise(1). .SH PLATFORMS Both DOS and Unix versions have been built.

Bugs tend actually to be fixed if they can be isolated, so it is in your interest to report them in such a way that they can be easily reproduced. The program gives errors if element lengths are well away from a half-wave (by a factor of ~3) due to a breakdown in the equations.

Any improvements are written to a new file called .I filename.bes where filename is the name of the antenna description file created by .I input or .I first .LP When Yagi's are designed on paper, or using this program, its possible that they will be almost impossible to build, if their performance depends too critically on the dimensions. To determine if this is the case with a design, we run optimise with just the options 't' and 'T'. These specify the tolerance with which you can build the antenna, expressed as a standard deviation in mm. In this case, instead of trying to optimise a poor design, optimise will calculate the minimum gain, maximum VSWR, and minimum FB ratio of a number of designs, all slightly different from the input file. 99.7% of the components lie within 3 SD of the mean, so if you think you can cut elements to with 1 mm 99.7% of the time, specify t0.33. If you can put them in the boom to within 3 mm 99.7% of the time, specify T1. .LP If while .I optimise is running using the methods that require weights to be attached to the gain, FB, SWR etc, it becomes apparent, the weights are not optimum, its possible to pause the program and re-adjust the weights. If a file with the name of .I changes is created, the program will pause, then request new weights are entered at the keyboard. .SH AVAILABILITY .SH OPTIONS .TP .B \-d Print the default values of all the configureable parameters to stdout. Typing this option with any option that changes a parameter (see below) will display the new value of the parameter, rather than the default. .TP .B \-h Print a help message. .TP .B \-v Print verbose status information. .TP .B \-w Instead of optimising at one fixed frequency (the design frequency), this directs the program to optimise at 3 separate frequencies (lowest, design and highest) then to average data at all 3. This option is better for wideband antenna. Note that the input impedance printed is at the design frequency, *not* averaged over 3 frequencies. Averaging an impedance, is likely to give a very misleading impression. The impedance averaged over 3 frequencies can be 50+i0 Ohms, even if the VSWR is very poor over all 3 frequencies, as the following 3 pieces of data show. .br Z=147 + j 300 SWR= 15.46:1 .br Z=2 + j 100 SWR= 125:1 .br Z=1 - j 400 SWR= 3250:1 .br note in the above three cases, the average impedance is 50 + j 0, but average SWR is 1130:1. .TP .B \-O Over-optimisation allowed. By default, the program does not over-optimise a parameter. For example, an SWR of 1.01 is usually considered good enough and any change, as long as the SWR stayed good, typically below 1.1:1, would be allowed, even if the SWR rose. By default, FB's of 27 dB, VSWR's of 1.1 are acceptable. However, by using the .B \-O option, you can insist the program always improves things, no matter how good they are. .TP .TP .BI \-a Angular_stepsize When optimimising by trying to get a clean pattern, specifies the step size to use when looking for features in the pattern. If its set too small, the program runs slow. If its set too large, the program may miss features in the pattern, such as a sidelobe. Then the resulting antenna will have poor sidelobe performance, even though you think it will be good. The program attempts to calculate a sensible value, based on 1/10th the approximate 3 dB beamwidth, if you don't set. .TP .BI \-b boom_extension Generally speaking, the gain of a Yagi increases with boom length. Hence the optimiser would often give you a Yagi with a much longer boom than the input file. This may not be what you desire due to space restrictions. These long antennas often have high gain, but are very narrow in bandwidth. The default limits the antenna to 10x the original length, which means effectively there is no boom length limitation. You can adjust the percentage by setting .I boom_extension to whatever you wish. .I -b30 will limit the boom to no more than 30% more than the original length. .TP .BI \-c cleanliness_of_pattern Specify the number of dB down on the peak gain to aim to get the pattern. Any antenna pattern cleaner than this will not effect the fitness, nor will it be considered any better when comparing to antenna designs. 20 dB seems reasonable, so the default is 20, but this may of course change if it's deceided too. Check the source code to be certain (see REASONABLE_SIDELOBE in yagi.h). .TP .BI \-e elements is an integer which specifies the type of elements that are changed in the optimisation cycle. Possible values are: .br .in +1.5 1 - alter only the driven element(s) length (useful to bring to resonance) .br 2 - alter only the driven element position. Don't change its length. .br 4 - alter only the reflector length. The position is always at x=0. .br 8 - alter only the director lengths. Don't change positions. .br 16 - alter only the director positions. Don't change lengths. .br 32 - randomly adjust one element length, then makes all other the same. Don't change the positions. .br 64 - apply a linear taper to the lengths. .br 128 - Set the driven element to a resonate length. It may/may-not be altered after the first run, depending on the whether or not '1' is invoked too. Eg -e128 will make it resonate and keep it there forever. However '-e129' will bring to resonance, then alter to maximuse performance. .in -1.5 The elements altered is made from a logical AND of the above, so for example to alter everything, except the driven element length, use -e30, since 2+4+8+16=30. The default is equivalent to .I -e31 , which changes everything possible. Note the reflector position is *never* changed. It's always at x=0. .TP .TP .BI \-f FBratio When optimising an antenna, consider any FB ratio greater than .I FBratio dB to be equal to .I FBratio dB. This avoids optimising to a very high FB ratio, which is impracticable, as the bandwidth over which this FB ratio will be maintained is very small and mechanical considerations will prevent you from constructing it with such a high FB ratio anyway. If this was not prevented, you might just happen to get an antenna with 100 dB FB ratio, but poor gain and swr. Since by default all parameters must improve, the optimisation routine will most likely never being able to improve on the 100 dB FB ratio, so no improvement will result. Most people would prefer to get a few extra dB of gain, even if the FB ratio dropped to 30 dB. .TP .BI \-g GA_optimisation_method Use a genetic algorithm. With the genetic algorithm, the program does not take any account any of the initial lengths/positions of elements specified in the input file. Rather it works by initialising a number of different antenna, then computing a 'fitness' value for each. The fitness value can depend on the gain, FB, real part of the input impedance, reactive part of the input impedance, VSWR or the level of the sidelobes. The integer after the g tells the optimiser what to consider. -g1 Use gain .br -g2 Use FB .br -g4 Use R .br -g8 Use X .br -g16 Use the SWR .br -g32 Use the level of the sidelobes. .br You can use a logical AND of these, so for example -g49 will use a genetic algorithm, optimising for gain, swr and sidelobe level, since 1(gain)+16(SWR)+32(sidelobe level)=49. .TP .BI \-l percent is a parameter (floating point number) which specifies the maximum percentage change in the positions or lengths of an elements at each iteration. If the option is not used, it will be set internally at 10% for the first 25% of the iterations, 1% for the next 25%, 0.1% for the third 25% of the iterations and 0.01% for the last 25% of the iterations. If set to a positive number x (eg optimise -l 0.3 145e10) then the percentage will be set at x% for 25% of iterations, x/10 for the next 25%, x/100 for the next 25 and x/1000 for the last 25%. If set to a negative number y (eg optimise -l -0.5 145e10) then the paramters will stay fixed at y% (in this example 0.5%) all the time. .TP .BI \-m min_offset-from_peak Sets the minimum angle in degrees offset from theta=90 degrees, where the side lobes start and the main lobe finishes. The higher the gain, the smaller it should be. It is set internally if not set on the command line. .TP .BI \-o optimisation_criteria .br .in +1.5 1 - Assume better if the gain has increased. .br 2 - Assume better if the front to back ratio has improved. .br 4 - Assume better if the real part of the input impedance is closer to the value that the program was compiled for, or set using the '-Z' option. This will usually be 50 Ohms, but you may wish to set this to 12.5 Ohms if you use a 4:1 balun. Generally you can get higher gain from a Yagi if you allow the input impedance to fall, but of course feeding it becomes more difficult. .br 8 - Assume better if the magnitude of the reactive component of the input impedance is lower (ie. the antenna is nearer resonance). .br 16 - Assume better if the VSWR is lower. .br 32 - Assume better if the level of all sidelobes is lower. .in -1.5 The .I optimisation_criteria may be formed from a logical AND of these numbers, so for example choosing .I -o19 will only consider a revised antenna better than the previous, if the SWR, gain and F/B ratio have all simultaneously improved. .br Clearly an antenna which originally had 12 dB gain and 1.01:1 VSWR but then changes to 20 dB gain @ 1.02:1 VSWR, would to most people be better, even though the VSWR has increased. By default, .I optimise only optimises to sensible maximums, so to not let the optimisation stall prematurely. By running .I optimise with no arguments, the program will list the limits of acceptability. These might be typically F/B ratio > 27 dB, VSWR < 1.1:1, magnitude of input reactance less than 5 Ohms and the real part of the input impedance within 5 Ohms of Zo. Choosing .I -o19 (1+2+16=19) will optimise for gain (since G=1), FB (since FB=2) and SWR (Since SWR=16), but would consider a higher gain and FB ratio antenna better than a previous one, even if the SWR rose, as long as it stayed below 1.1:1 (or as was set during compilation). The default behaviour (no options) is equivalent to .I -o37 which optimiseas for gain(1), the real part of the input impedance(4) and sidelobes(32) but this may be changed at any time, so type .I optimise -d to check the current settings. If you insist on the program optimisang for the very best of all selected parameters, use the -O option too, but be warned the optimisation will probely stick once it gets one parameter really good. .TP .BI \-p population This determines the initial population used with the genetic algorithm. .TP .BI \-r resistance When optimising an antenna, consider any input resistance closer to Zo (usually 50 Ohms) than .I resistance Ohms to be acceptable. This avoids optimising to an input resistance too close to Zo, which is impracticable, as the bandwidth over which the input resistance could be maintained is very small and mechanical considerations will prevent you from constructing the antenna with such an ideal input resistance. If this was not prevented, you might just happen to get an antenna with an input resistance of 50.000001 Ohms, but poor gain, FB and possibly even a poor swr, if the antenna is well away from resonance. Since by default all parameters must improve, the optimisation routine will get most likely never being able to improve on the antenna, whereas we might be happier with a few more dB gain, if the input resistance went to 50.1 Ohms. It should be noted that the default optimisation routine never uses the input resistance directly (only VSWR), so this option cant be used without the '-o' option to optimise for other than the default parameters (gain, VSWR and FB ratio). .TP .BI \-s swr When optimising an antenna, consider any SWR less than .I swr to be equal to .I swr This avoids optimising to a very low swr, which is impracticable, as the bandwidth over which such a low swr could be maintained would be very small and mechanical considerations will prevent you from constructing such an antenna anyway. If this is was not prevented, you might just happen to get an antenna with an swr of 1.000000000001:1, but poor gain, FB ratio. Since by default all parameters must improve, the optimisation routine will most likely never being able to improve on the antenna, even though in practice you would like to get a few extra dB of gain if the SWR would rise to 1.02:1. The default was equivalent to .I -s1.1 but run .I optimise -d to display this and any other defaults. .TP .BI \-t length_tolerance .I length_tolerance is the standard deviation in mm of the accuracy with which you can cut elements. Since 99.7% of elements will be with 3 standard deviations of the mean length (stats theory says this), set -t0.2 if virtually all (well 99.7%) of elements are within 3x0.2=0.6 mm of the correct length. This option *must* be used with the '-T' option and can't be used with any other options apart from '-Z', '-v' and '-d'. .TP .BI \-x reactance When optimising an antenna, consider any input reactance of less than .I reactance to be .I reactance. This avoids over optimising the reactance, at the expense of something else. .TP .BI \-A auto_gain When the .I auto_gain option is used. the program maximes the gain of the antenna (ignoring all other parameters such as SWR, FB ratio etc) by adjusting the length (not position) of one element only. -A-1 will maximuse the gain, by adjusting the length of the reflector, -A0 will maximise the gain by adjusting the length of the driven element. Its generally *not* a good idea to maximise the gain by adjusting the driven element, but the program lets you do it, but using the option -A0. Using -A1 will maximise gain by adjusting the length of the first director, -A2 the second director and so on, up to the last director. You must check carefully that the input impedance in particular does not fall to silly values if you use this option. On a yagi with many elements (> 10 or so), you can pretty safely maximise the 8th or more director, but doing it on the reflector, driven element or early directors often leads to silly input impedances - so beware! Note, no matter how many iterations you specify, this process is only done once.Its unlikely you will be able to do it again, without things going out of hand, but if you must do it, you must re-run 'optimise' again. .TP .BI \-C currents_similar If this option is used, where .I currents_similar is an integer, the program looks to make the currents in the last .I currents_similar elements as similar as possible. It computes the sum of the squares of the deviations of the absolute values of the element currents from the mean. If this falls, and the criteria specified with the -W option is also satisfied, the antenna is considered better. If .I currents_similar is three less than the number of directors, it tries to make the currents in the the directors (but ignoringing the first 3) all similar. If .I currents_similar is equal to the number of directors, it tries to make all the directors have similar currents. If .I currents_similar is one more than the number of directors, it tries to make all the directors and the reflector have similar currents. If .I currents_similar is equal to the total number of elements, then it fails with an error message. .TP .BI \-F weight_FB is the floating point number (default 1.0) specifying the weight to attach to the FB ratio of the antenna when using the '-W' option, which calculates a fitness for the antenna based on one or more parameters (FB, gain, input resistance, input reactance, SWR, cleanliness of antenna pattern). The '-F' option is similar to the options -G, -P, -R, -S, -X (which specify weights for gain, pattern cleanliness, input resistance, SWR and input reactance). When using the -W option the exact algorithm used to compute the fitness (and hence the effect of this parameter) is best checked by looking at the source code (see perform.c). This is one area of constant program improvement/changes/development, so its difficult to say exactly the effect the parameter has. However, increasing the weight of a parameter (using the -F, -G, -R, -S or -X options) will make the associated parameter have a greater effect on the fitness. However, unless you optimise for a high FB ratio with the -W option, then setting the -F option will have no effect. For example, setting the options -F2.5 -W1 is a complete waste of time. There you have used the -W1 option to optimise only for gain (see -W option section of man page) but have changed the weight of the FB ratio from its default 1.0 to 2.5. If you are not optimising for FB ratio, the weight you attach to it is irrelavent. .TP .BI \-G weight_gain is the floating point number (default 1.0) specifying the weight to attach to the gain of the antenna when using the '-W' option, which calculates a fitness for the antenna based on one or more parameters (FB, gain, input resistance, input reactance, SWR, cleanliness of antenna pattern). The '-G' option is similar to the options -F, -P, -R, -S, -X (which specify weights for FB ratio, pattern cleanliness, input resistance, SWR and input reactance). When using the -W option the exact algorithm used to compute the fitness (and hence the effect of this parameter) is best checked by looking at the source code (see perform.c). This is one area of constant program improvement/changes/development, so its difficult to say exactly the effect the parameter has. However, increasing the weight of a parameter (using the -F, -G, -R, -S or -X options) will make the associated parameter have a greater effect on the fitness. However, unless you optimise for gain with the -W option, then setting the -G option will have no effect. For example, setting the options -G2.5 -W2 is a complete waste of time. There you have used the -W2 option to optimise only for FB ratio (see -W option section of man page) but have changed the weight of the gain from its default 1.0 to 2.5. If you are not optimising for gain, the weight you attach to it is irrelavent. .TP .BI \-K keep_for_tries .br .I keep_for_tries is the number of tries for the optimise to persist using the original data file as the starting point for optimisation. By default it is 1, which means the program immediately looks from a new position once a better one is found. It is theeoretically possible that this might result in a quick, but poor local maximum. If however, .I keep_for_tries is 1000, it will stay at a position for 1000 iterations after finding the last best result, before considering this to be a global optimum. Then it starts for the new position. In practice, I have found this option to make matters worst in most cases. It was added to avoid the local-minimum problem, but it appears the optimisation surface is pretty smooth, so it just slows the program, without gaining much. Anyway, it can stay as an option, but check the results with/without carefully before using extensively. .TP .BI \-P pattern_cleanlyiness is the floating point number (default 1.0) specifying the weight to attach to the cleanness of the antenna pattern when using the '-W' option, which calculates a fitness for the antenna based on one or more parameters (FB, gain, input resistance, input reactance, SWR, cleanliness of antenna pattern). The '-P' option is similar to the options -F, -G, -R, -S, -X (which specify weights for FB ratio, gain, input resistance, SWR and input reactance). When using the -W option the exact algorithm used to compute the fitness (and hence the effect of this parameter) is best checked by looking at the source code (see perform.c). This is one area of constant program improvement/changes/development, so its difficult to say exactly the effect the parameter has. However, increasing the weight of a parameter (using the -F, -G, -R, -S or -X options) will make the associated parameter have a greater effect on the fitness. However, unless you optimise for a clean antenna pattern with the -W option, then setting the -P option will have no effect. For example, setting the options -P2.5 -W1 is a complete waste of time. There you have used the -W1 option to optimise only for gain (see -W option section of man page) but have changed the weight of the pattern cleanliness from its default 1.0 to 2.5. If you are not optimising for a clean radiation pattern, the weight you attach to it is irrelavent. With appropiate use of the -W option (eg -W49 for gain, SWR and a clean pattern), the computer program finds the level of the most significant sidelobe, wherever it may be outside the main bean. It then optimises to reduce this. The -P option tells it how much weight to put on reducing this sidelobe. .TP .BI \-R weight_resistance is the floating point number (default 1.0) specifying the weight to attach to the obtaining an input resistance close to Zo on the antenna when using the '-W' option, which calculates a fitness for the antenna based on one or more parameters (FB, gain, input resistance, input reactance, SWR, cleanliness of antenna pattern). The '-R' option is similar to the options -F, -G, -P, -S, -X (which specify weights for FB, gain, pattern cleanliness, SWR and input reactance). When using the -W option the exact algorithm used to compute the fitness (and hence the effect of this parameter) is best checked by looking at the source code (see perform.c). This is one area of constant program improvement/changes/development, so its difficult to say exactly the effect the parameter has. However, increasing the weight of a parameter (using the -F, -G, -R, -S or -X options) will make the associated parameter have a greater effect on the fitness. However, unless you optimise for an an input resistance close to Zo, with the -W option, then setting the -R option will have no effect. For example, setting the options -R2.5 -W1 is a complete waste of time. There you have used the -W1 option to optimise only for gain (see -W option section of man page) but have changed the weight of the resistance from its default 1.0 to 2.5. If you are not optimising for an input resistance close to Zo, the weight you attach to it is irrelavent. .TP .BI \-S weight_swr is the floating point number (default 1.0) specifying the weight to attach to the SWR of the antenna when using the '-W' option, which calculates a fitness for the antenna based on one or more parameters (FB, gain, input resistance, input reactance, SWR, cleanliness of antenna pattern). The '-S' option is similar to the options -F, -G, -P, -R, -X (which specify weights for FB, gain, pattern cleanliness, input resistance and input reactance). When using the -W option the exact algorithm used to compute the fitness (and hence the effect of this parameter) is best checked by looking at the source code (see perform.c). This is one area of constant program improvement/changes/development, so its difficult to say exactly the effect the parameter has. However, increasing the weight of a parameter (using the -F, -G, -R, -S or -X options) will make the associated parameter have a greater effect on the fitness. However, unless you optimise for SWR with the -W option, then setting the -S option will have no effect. For example, setting the options -S2.5 -W1 is a complete waste of time. There you have used the -W1 option to optimise only for gain (see -W option section of man page) but have changed the weight of the SWR from its default 1.0 to 2.5. If you are not optimising for SWR, the weight you attach to it is irrelavent. .TP .BI \-T position_tolerance .I position_tolerance is the standard deviation in mm of the accuracy with which you can cut elements. Since 99.7% of elements will be with 3 standard deviations of the correct position (stats theory says this), set -T2 if virtually all (well 99.7%) of elements are within 3x2=6 mm of the correct position.This option *must* be used with the '-t' option and can't be used with any other options apart from '-Z', '-v' and '-d'. .TP .BI \-W Weighted_algorithm Try to get an antenna which is better according to a weighted combination of parameters, rather than require them all to improve. The integer specifies what to consider in the weighted parameters. .br W1 Gain. .br W2 FB .br W4 R .br W8 X .br W16 SWR .br W32 SIDE_LOBE .br You can logically AND these together, so for example -W3 will optimise using a weighted combination of gain and FB. -W49, will use a weighted combination of gain, swr and sidelobe leve, since 32+16+1=49. .TP .BI \-X weight_reactance is the floating point number (default 1.0) specifying the weight to attach to achieving a low input reactance on the antenna when using the '-W' option, which calculates a fitness for the antenna based on one or more parameters (FB, gain, input resistance, input reactance, SWR, cleanliness of antenna pattern). The '-X' option is similar to the options -F, G, -P, -R and -S (which specify weights for FB ratio, gain, pattern cleanliness, input resistance, and SWR). When using the -W option the exact algorithm used to compute the fitness (and hence the effect of this parameter) is best checked by looking at the source code (see perform.c). This is one area of constant program improvement/changes/development, so its difficult to say exactly the effect the parameter has. However, increasing the weight of a parameter (using the -F, -G, -R, -S or -X options) will make the associated parameter have a greater effect on the fitness. However, unless you optimise for a low input reactance with the -W option, then setting the -X option will have no effect. For example, setting the options -X2.5 -W1 is a complete waste of time. There you have used the -W1 option to optimise only for gain (see -W option section of man page) but have changed the weight of the reactiance from its default 1.0 to 2.5. If you are not optimising for a low input reactance, the weight you attach to it is irrelavent. .TP .BI \-Z Zo .br .I Zo is the characteristic impedance used when evaluating the VSWR, reflection coefficient and other similar calculations. The optimiser usually tries to bring the input impedance of the antenna to this value. It is set by default to 50 Ohms, so the default is equivalent to .I -Z50 but may be set to any positive number. Set to 12.5 Ohms if you are going to feed the antenna with a 4:1 balun. Generally speaking, the gain of a Yagi can be higher for low input impedances, but of course such antennas are more difficult to feed. .TP .I filename This is the name of the file containing the antenna description. It is expected to be in a format created by either .I input or .I first - two other programs in the .I Yagi-Uda project. This is an ASCII text file. .TP .I iterations is an integer specifying the number of iterations for the optimiser to perform to try to get the best antenna. Time will limit the number you choose. 1000 iterations of a 1ele yagi takes about 5 seconds, a 6ele approximately 60 seconds, an 11 element 350 seconds, a 20 element 1030 seconds, a 33ele 2440 seconds, a 50element 5400 seconds, 100ele 21320 seconds all on an old 25MHz 486 PC with no external cache. When using the .I -A option the .I iterations is automatically set internally so only one attempt is made. When using the '-t' and '-T' options, .I iterations specifies the number of iterations to attempt to get a poorer design, to check the sensitivity of the design to small manufacturing tolerances. .SH EXAMPLES Here are a number of examples of using .I optimise. .PP 1) optimise 5ele 1000 .PP Here the file 5ele will be optimised using the default system for 1000 iterations. The default might typically require gain, FB and SWR to all improve, but this may be changed at any time. In any case, the program tells you what its optimising for. By default the program will only optimise to the selected parameters are good, not over-optimising any one at the detrement of the others. 2) optimise -b30 -f50 -s2 5ele 1000 .PP This is similar to above, but the boom can not extend by more than 30% from its original length, FB ratios above 50 dB are considered acceptable, as are SWR's less than 2:1. The optimised resultant antenna is likely to have better FB ratio, but poorer SWR than in (1) above. 3) optimise -o1 5ele 1000 .PP This will simply optimise 5ele for maximum forward gain. The resultant antenna may have a poor FB ratio and is likely to have an unacceptably low input impedance and hence high VSWR. This is not a very sensible method of optimisation. 4) optimise -W49 -l7 5ele 10000 .PP This will optimise the file 5ele using for 10000 iterations. It will require that the weighted performance of the antenna in three important parameters (gain, sidelobe level and SWR) improves from one design to the next. One or two parameters can actually get worst from one design to the next, but the weighted performance is better. The positions of the elements or lengths of elements will not change by more than 7% in each iteration. .PP 5) optimise -g -S30 -G50 -F20 -p1500 5ele 10000 .PP This will optimise the file 5ele using a genetic algorithm. 1500 antennas will be randomly designed. The performance of each of these will measured using a 'fitness' function, weighted 30% to SWR, 50% to gain and 20% to FB ratio. The probability of breading from a pair of antennas is proportional to the fitness function. .PP 6) optimise -w atv_antenna 10000 .PP This will optimise the file atv_antenna for a best average performance over a wide band. The progrram calculates the gain, FB and SWR at three frequencies, then computes an average (mean) performance of the antenna over the band. N iterations will take 3x as long to execute as N iterations on the same antenna without the '-w' option. .PP 7) optimise -t0.1 -T1 good_design 100 .PP This will take the file good_design and make 100 different antennas from it, to simulate the effects of building tolerances. Each element is assumed to be cut so that the mean error of all elements is 0 mm, but a standard deviation of 0.1 mm, so 68.4% of element lengths are within 0.1 mm, 95.4% within 0.2 mm and 99.7% with in 0.3 mm. The accuracy of placing elements along the boom is much lower, so here we have specified a standard deviation of 1.0 mm, so 68.6% of elements are placed within 1 mm of the correct position, 95.4% within 2 mm of the correct position etc. The program will report the *worst* performances achieved. If the performance dips too mush, then you either need to build them better, or get a design that's less critical! .SH STOPPING .I Optimise will stop after the number of iterations specified in the parameter .I iterations. It will also stop if a file .I stop exits in the current directory of the executable .I optimise This file can of course only be created using a multi-tasking operating system such as Unix. It is *not* advisable to stop the program by hitting the DEL key (Unix) or CONTROL-C (DOS), as one of the files may be open at the time, resulting in an empty file. Files are not open for any longer than necessary (they are closed immediately after writing to them), so this is not a likely occurrence, but can still occur. .SH LIMITATIONS I'm not aware of any limitations, apart from that filenames, including full path, can't exceed 90 characters. .SH FILES .nf filename Antenna description, created by input or first. filename.up Update file, listing achievements of optimise. filename.bes Best file, containing the best design to date. changes File that causes the program to pause to re-adjust weights. stop File that stops optimisation process. .br .fi .SH "SEE ALSO" first(1), input(1), output(1), yagi(1), first(5), input(5) output(5) and optimise(5). .SH PLATFORMS Both DOS and Unix versions have been built. The DOS version as distributed requires a 386 PC with a 387 maths coprocessor. Although I have altered the source to make it more compatible with DOS (reduced file name lengths etc), my wish is to build a decent program, rather than fit the program to an outdated operating system. If there is a *good* reason to use code that is incompatible with DOS, this will be done. .br Since .I optimise takes a while to optimise an antenna (I've optimised one design for a week), it is obviously more sensible to build this program under a multi-tasking operating system, as otherwise a PC can be tied up for days. .SH BUGS Bugs should be reported to .BR david.kirkby@onetel.net . Bugs tend actually to be fixed if they can be isolated, so it is in your interest to report them in such a way that they can be easily reproduced. The program will dump core (crash) if asked to optimise a 1ele beam, without any arguments. This is because a 1ele beam has no parasitic elements and by default the program only changes parasitic elements. Some of the options are not checked for sensible values, although most are now checked and report if they are out of range. If the user specifies very large manufacturing errors using the '-t' and '-T' options, its possible for elements to overlap or for element lengths to become negative. This will cause numerical errors. Any reasonable values will not cause this. On long Yagi's (50 elements) optimise can go a bit silly. It can optimise say a 1296MHz Yagi to get 20 dB at 1296 MHz, but less than 0 dB at only 1 MHz away. Needs some thought! The level of the sidelobes is not computed with the GA or some other optimisation types. This will be corrected later. All those I don't know about. .nf .SH AUTHORS Dr. David Kirkby G8WRB (david.kirkby@onetel.net). with help with converting to DOS from Dr. Joe Mack NA3T (mack@fcrfv2.ncifcrf.gov) yagiuda-1.19.orig/man/man1/dipole.10000644000175000017500000000224510264163561015272 0ustar pg4ipg4i.TH YAGI 1 "24th October 2000 " "Version 1.16" .de BP .sp .ns .ti -.2i \(** .. .SH NAME dipole \- Yagi-Uda project file.

This is not calculated unless the '-c' option is used, and then only on some optimisation techniques. .SH Example of a .gai File The following is a small section of the .gai file. .nf f(MHz) theta gain-E(dBi) G(E)-peak phi gain-H(dBi) G(H)-peak 144.0000 -90.0000 -12.5584 -21.9444 -180.0000 -12.5584 -21.9444 .br 144.0000 -45.0000 -7.3507 -16.7367 -135.0000 -3.5971 -12.9830 .br 144.0000 0.0000 -999.0000 -1008.3860 -90.0000 -0.9010 -10.2870 .br 144.0000 45.0000 0.1848 -9.2012 -45.0000 4.0261 -5.3599 .br 144.0000 90.0000 9.3860 0.0000 0.0000 9.3860 0.0000 .br 144.0000 135.0000 0.1848 -9.2012 45.0000 4.0261 -5.3599 .br 144.0000 180.0000 -999.0000 -1008.3860 90.0000 -0.9010 -10.2870 .br 144.0000 225.0000 -7.3507 -16.7367 135.0000 -3.5971 -12.9830 .br 144.0000 270.0000 -12.5584 -21.9444 180.0000 -12.5584 -21.9444 .br .SH What is what in the .gai file The f(MHz) column is the frequency in MHz. .br The theta column is the angle theta, for which the next two columns refer. .br The gain-E(dBi) is the gain at theta, relative to an isotropic radiator. This is the E-plane gain. Hence at the peak (theta), this gives the peak forward gain. .br The G(E)-peak is the gain at theta, relative to the peak gain. Hence at the peak (theta=90 degrees), this is zero. .br The phi column has nothing to do with the previous 3 columns. It is the angle for which the next two columns refer. .br The gain-H(dBi) is the gain at phi, relative to an isotropic radiator. This is the H-plane gain. Hence at the peak (phi=0), this gives the peak forward gain. .br The G(H)-peak is the gain at phi, relative to the peak gain. Hence at the peak (phi=0 degrees), this is zero. .br .SH Example of a .up File The .up file list the improvements made by optimise to an antenna design. Starting from the original design, the file is appended each time a new better design is found. Here is an example, where the final line is the performance of the 4ele beam with the .dat file shown earlier. .nf 1 7.57dBi, 16.93dB F/B, Z=(31.77-56.34j) Ohms, VSWR=3.95, SL=16.95 dB .br 84 7.58dBi, 16.93dB F/B, Z=(31.78-56.32j) Ohms, VSWR=3.95, SL=16.95 dB .br 623 7.58dBi, 16.93dB F/B, Z=(31.78-56.28j) Ohms, VSWR=3.95, SL=16.95 dB .br 89345 9.74dBi, 103.06dB F/B, Z=(37.55 +1.61j) Ohms, VSWR=1.33, SL=17.78 dB .br .SH What is what in the .up file The first column is an integer specifying the iteration. The other columns, going from left to right are gain(dBi), FB, input impedance, VSWR and level of the most significant sidelobe, in dB down on the peak gain. .SH "SEE ALS0" yagi(1), output(1), input(1), optimise(1), first(1) and yagi(5). .SH AUTHORS Dr. David Kirkby G8WRB (david.kirkby@onetel.net), with help with converting to DOS from Dr. Joe Mack NA3T (mack@fcrfv2.ncifcrf.gov). yagiuda-1.19.orig/man/man5/yagi.50000644000175000017500000000535310264163560014761 0ustar pg4ipg4i'\" e .\" -*- nroff -*- .\" This man page must be preprocessed with eqn. .ie \n(.g .ds ic \/ .el .ds ic \^ .TH YAGI 5 "24th October 2000" "Yagi version 1.16" .SH NAME yagi \- yagi binary output format .SH DESCRIPTION This manual page describes the output format of the file created by the .IR Yagi-Uda project's .IR yagi program. The file is a binary file with a header of 100 bytes. The header consists of: .nf .ul offset(bytes) information data-type 0 elements int 4 driven int 8 parasitic int 12 min_frequency double 20 max_frequency double 28 design frequency double 36 step_frequency double 44 angular_step double 52 0 double . . . . . . . . . 92 0 double Following the header, there starts the coordinates(x,y,l) of each element and the voltage applied to each element. Then we write the element currents one after the other, at each frequency. Hence the element currents will be written 12,000 times with a 3 element yagi analysed at 4,000 different frequencies. All complex data is stored in a structure of type fcomplex, defined as: struct fcomplex {double real, double imaginary}; .ul offset(bytes) information data-type 100 x1 double /* coordinates */ 108 y1 double 116 l1 double 100+(n-1)*24 x_n double 100+(n-1)*24+8 y_n double 100+(n-1)*24+16 l_n double ..............
