It's described on http://www.qsl.net/ka5ruz/. He calls it the "RUZ" antenna. It looks fairly simple to build, simpler than other CFA or EH antenna descriptions I have seen, so maybe I will give it a try this summer? Well, I built it. It gives an SWR equivalent to having an unterminated coaxial cable - in the order of 1:6 or 1:10, i.e. the maximum that I can measure. I first tried it with 10 m coax, about half wavelength on 20 m, then I thought I would try it with around a quarter-wave (~5 m) to transform the high impedance to a low one. That didn't help much. However, my K2 antenna tuner can tune the antenna with 5 m cable and I can hear signals - even a rare one like OJ0 (not too far from LA-land!), but it is several S-points under my 75 horizontal loop in signal strength. I haven't tried to transmit yet. Pity. I emailed KA5RUZ re the antenna. He emailed a very nice response encouraging me to try it, but he gave no further technical info. Oh, well. Maybe I'll give STLs a try when I can. Andy |
