Re: Antenna for KX-1

This antenna has worked great for me with the KX-1 autotuner on 80, 40, 30 and 20:

I bought a 50 ft spool of speaker wire from Radio Shack and un-zipped it to make two 50 ft wires. I think it's 18 gauge, but I'm sure that's not critical. Mine actually measured 51 ft 8 inches long (and I'm sure that's not critical either) Get one wire as high in the air as you can via any handy support(s) and lay the other on the ground - straight if I can, random directions if not. By the if I'm in, say, a third floor hotel room, one wire might go out the window to a tree in the parking lot, and the counterpoise drops out the window and goes along the ground next to the building.

Re: Antenna for KX-1

I used to think, :just put a wire in the ocean...and voila good ground".

Not so....need "area" of contact....bronze screen wire cage works great.

Re: Antenna for KX-1

Yeah, you're right, Susan.

I suspect our "counterpoise" wires are not so much acting as a ground, but
rather are the other half of a doublet, occupying a position some distance
above effective ground.
