What if I'm using a battery-operated receiver and want to have an external

Bill,
It gets a little complex, but actually by connecting the parallel wires
in a coil like that together, you've caused a mighty phase cancelation and \
defeated the purpose of the long wire.
What you want is either an antenna that's tuned to the frequency you want
to hear, hard because you
Those are called loop antennas and are a whole lot of turns of fine wire
wound flat like a pancake. But they have a pretty narrow bandwidth so will
only do well at a small portion of the bands you want to hear. That's why I
didn't reccommend one for general shortwave listening.

I've always wanted a big horizontal loop like that except I'd
like to feed it with open wire line to a modern

the nevada desert that was 1400 feet on a side, up at 60 feet. Now that's

william,
You don't ground the antenna except in some weird cases.
Every antenna is actually two elements, one may be a wire or a vertical
whip, and the other is often ground.
Or you can have so-called dipoles which are two identical elements end to end.
The arguments about what is a real ground
, kind of like dog training I guess.
Thanks again.

Does your receiver have two antenna connections or an antenna and a ground?

Usually, perticularly inolder places, a plumbing vent pipe is grounded.

fooled.
It won't hurt anything, just won't perform as well as it might.

The best ham antennas I have ever had were full-wave loop antennas. On 75
