Modelling has shown the formulae to be out a bit at the higher frequencies. I have only built a 440mhz version which works very well but would like to hear about your results. From these samples, and computer modelling, I developed the program. I could not find any published formula for them but only sample antennas. It has the yagis gain and the quads direct feed and signal capture. The quagi may be the best of two worlds.

Verticals covers all the common types with a coil calculator built in for the antennas that require them. This program uses different formulae for 2, 3 or multi-element designs and includes element tapering. It produces maximum gain but requires tweaking for the number of elements. The yagi-uda antenna is the most recognized 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. It is very broadband for a dipole and makes a great field day antenna. Made out of coax, it matches closely to 50 ohms and can be set up horizontally or in an inverted V. The coaxial dipole or bazooka is the best keep secret. The gain is always less than a yagi with equivalent numbers but other factors still make it the better choice in my opinion. The gain per element reduces with large numbers. Gain is roughly 9.4 db for a 3 element and. I just replaced my original version quad with a new V3 version that is 30% smaller and almost as much gain. See WHY QUADS for information on feeding and choice of a quad. I also developed 50, 75 and 125 ohm feeding. This allowed me to tweak the original formulae for maximum gain. 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. I find this best for HF or VHF with few elements. No other quad program uses this information. He discovered that odd number of elements perform better than even and developed the wire size scaling. 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. It is designed for 50 ohms and is the tried and true method. The Standard quad is designed from the textbook equations and is compliments of Roger Clement KC5LCA. If you discover anything that would make a program better or more accurate, please forward the info to me. They are continually evolving as I gather new information. Originally I started writing the programs for my own use but I decided to make them available for the amateur community. There are lots of good websites out there. If you are new to building, check out other sites for construction details. MOST ARE AVAILABLE ON THE 2003 AMATEUR FUNK ( German Ham Radio magazine) CD. Most programs have inch and metric calculations. The program will give an error 13 when you try to compute. Also some European machines use a comma instead of the decimal point.

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.

The programs do not write to the Windows registry so just delete the files when you no longer wish to keep them. To get you started, I have made up programs that cover the most common types of antennas and a few experimental designs. Hams go where no engineer has gone before. If not, you will still have the satisfaction of working that DX with a homebrew antenna. We are still looking for that PERFECT antenna that is small, easy to build and is super efficient. We do not know all the rules so we go ahead and build the antennas anyways, Some work, some don't. For a hundred years the amateurs have made more breakthroughs in antenna design than the professionals. One area that is still open to amateurs is in antenna building.
