Default Dummy Load Antenna

You would need a balun (rf transformer) to match to that antenna ...

Then you would need a suitable name for it. Let me see, we are mating
up a "dummy load" with a "dipole." 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. Who needs an
antenna anyway?

Hmmm, sounds like that you mention might be the "Original DummyPole!"
Or, "DummyPole I."

This new design should probably be named "DummyPole II." grin

Nope. 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...
