One area that is still open to amateurs is in antenna building. For a hundred years the amateurs have made more breakthroughs in antenna design than the professionals. We do not know all the rules so we go ahead and build the antennas anyways, Some work, some don't.

We are still looking for that PERFECT antenna that is small, easy to build and is super efficient. You may be that designer. If not, you will still have the satisfaction of working that DX with a homebrew antenna.

YW (Yagi for Windows) Version 2.0, March 16, 2006. YW will get you very close to a final design — one where you can simply. Group (by default called “Antenna Book Software”) containing all the icons for the Antenna Book programs. Fig 1—A typical YW main screen. Download yagi designer software for windows for free. Home & Hobby software downloads - Yagi Designer by Goforth Laboratories and many more programs are available for instant and free download.

Hams go where no engineer has gone before. To get you started, I have made up programs that cover the most common types of antennas and a few experimental designs. Click on the icons to download. The programs do not write to the Windows registry so just delete the files when you no longer wish to keep them. THEY DO REQUIRE THAT THE DLLS ARE UP TO DATE, SO IF YOU GET AN ERROR OR THE PROGRAMS WILL NOT RUN, DOWNLOAD THE FULL VERSION OF HF QUAD 2002 AND IT WILL INSTALL THE PROPER DLLS SO ALL THE PROGRAMS WILL RUN. Also some European machines use a comma instead of the decimal point. The program will give an error 13 when you try to compute.

They require numbers like 14. 255 (14dot255) to be put in as 14,255 (14comma255). Most programs have inch and metric calculations. MOST ARE AVAILABLE ON THE 2003 AMATEUR FUNK ( German Ham Radio magazine) CD. There are few construction details here.

I am a builder not a writer. If you are new to building, check out other sites for construction details. There are lots of good websites out there. Originally I started writing the programs for my own use but I decided to make them available for the amateur community.

They are continually evolving as I gather new information. If you discover anything that would make a program better or more accurate, please forward the info to me. THX ahead of time.. Quads are my specialty. The Standard quad is designed from the textbook equations and is compliments of Roger Clement KC5LCA.

It is designed for 50 ohms and is the tried and true method. The HF version is my program taken from research done by W3GNR who must have spent many hours of field research to develop his formulae. He discovered that odd number of elements perform better than even and developed the wire size scaling. No other quad program uses this information.

I find this best for HF or VHF with few elements. My version 3 ( 50 ohm error corrected Dec16/03 ) was developed from the original HF version but was optimized using two different computer modelling programs. This allowed me to tweak the original formulae for maximum gain. I also developed 50, 75 and 125 ohm feeding. See for information on feeding and choice of a quad. I just replaced my original version quad with a new V3 version that is 30% smaller and almost as much gain. Gain is roughly 9.4 db for a 3 element and.9 more for each element.

The gain per element reduces with large numbers. The gain is always less than a yagi with equivalent numbers but other factors still make it the better choice in my opinion.. The coaxial dipole or bazooka is the best keep secret. Made out of coax, it matches closely to 50 ohms and can be set up horizontally or in an inverted V.

It is very broadband for a dipole and makes a great field day antenna. The loaded dipole (V2) is not as good as a full size antenna but it can be used in limited spaces and even indoors. The yagi-uda antenna is the most recognized antenna. It produces maximum gain but requires tweaking for the number of elements. This program uses different formulae for 2, 3 or multi-element designs and includes element tapering..

Verticals covers all the common types with a coil calculator built in for the antennas that require them.The quagi may be the best of two worlds. It has the yagis gain and the quads direct feed and signal capture. I could not find any published formula for them but only sample antennas. From these samples, and computer modelling, I developed the program.
