How about "Dummy-Pole?" grin Been there, done that. About 30 years ago, I went on a field day exercise where one of the HF stations was running a lightbulb on a pole for an antenna. 100 watts RF, about 50ft of RG-8/u, voltage stepped down with some kind of xfomer or balun, and a 150 watt incandescent light bulb. I don't recall how well they did, but I could see that the log was filling with contacts.

Or, "DummyPole I." This new design should probably be named "DummyPole II." grin Regards, JS |

I vaguely recall it was called a "lamptenna". Somewhat later, I helped build a dipole using four 4ft fluorescent tubes (two in each leg of the dipole hung horizontally on bamboo poles). The 96" length was about right for a 10 meter dipole. About 80 watts out got the bulbs to light up. Once lit, the tubes were quite conductive and made a functional transmit antenna and impressive light show. It was totally useless for CW, kinda marginal for SSB, and just great for AM. We had RTTY but couldn't find anyone to help test it. We never did figure out how to light up the bulbs so we could try receive. Various gross violations of the electrical code and of common sense were attempted with no useful results. There are those that can see the light... -- # Jeff Liebermann 150 Felker St #D Santa Cruz CA 95060 # 831-336-2558 # http://802.11junk.com # http://www.LearnByDestroying.com AE6KS |
