This article below was written by WA7RAI and will serve to introduce you to a computer program for designing Yagi antennas that you can download. I routinely use HFSS at work and own a personal seat for occasional consulting. The design program is best suited for antennas in the VHF UHF and Microwave frequencies because lower frequency antennas that have gains between 118 to 216 dBd tend to be physically impractical.

Lower frequency antennas that have these attributes tend to be physically impractical. Yagi Calculator is a Windows program that also runs well on Linux Ubuntu 810 under Wine to produce dimensions for a DL6WU style long Yagi antenna. In my case the antenna was completely made from discarded Yagi beam elements a junk box vertical.
Jerry Hall K1TD. According to Yagi Analyzer the simple program that comes with The ARRL Antenna Book3 the antenna has 106 dBi of free-space gain with the unwanted lobes suppressed by 20 dB–a reasonably clean pattern. VHFUHF Yagi Antenna Considerations – ARRL Antenna Book 20th Edition.
