Why didn't it work? Urban Economics O Sullivan Ebook Torrents. That was in the days before antenna design SW. It took apx another 1 year to 'tune' the antenna to get some 'real' f/g from it. It worked but it didn't work as it should have.
It certainly looks small! The 'bad' part was the fact that this was built using the 'handbook' dimensions. Designing Yagis I just love building yagis right from the first time I constructed a 5el, 20mtr monoband yagi on a 53' boom! The picture shows it in contrast to another home brew 3el, 15mtr monoband yagi on 21' boom. The sw is an excellent design tool provided some simple rules are followed. That's exactly the way I designed it! Was only was interested in covering the low phone portion of the 20mtr band and it did that in style. The 'bad' part was the low feed impedance but.
The final results are shown.Īs you see, the f/g was 10.3dBi with 28dB f/b ratio.
The starting point was a Japanese antenna (CL20, 31' boom). About 14 years ago, I used this sw to design a 4el 20mtr monoband yagi on a 41' boom. This fine antenna software is no longer offered and there's is no way to purchase it. Using the three programs, any antenna (wire, verticals, yagis, quads, etc) can be completely characterized in a few minutes over most any terrain. Written by Brian Beezley, the sw packages were called Yagi Optimizer, Antenna Optimizer and Terrain Analyser. During the early 1990s thru 1998, an excellent antenna analysis software was bought to market. WB Audio Section: K6JRF K6JRF's Page formerly W6FZC Yagi Design Techniques (Updated: May 21, 2010) This new section shows the actual design of a monoband yagi employing Yagi Optimizer, and Antenna Optimizer software to detail the steps required to initiate, analyze and complete the real-world design of any antenna.
