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. It would be

clifford, I've always wanted a big horizontal loop like that except I'd like to feed it with open wire line to a modern line tuner. The infamous broadcaster Art Bell had one out in the nevada desert that was 1400 feet on a side, up at 60 feet. Now that's an antenna to dream of. 73s Tom WA6IVG

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

Bill, Usually, perticularly inolder places, a plumbing vent pipe is grounded. but if there is any chance of PVC pipe anywhere in the stack, you might get fooled. It won't hurt anything, just won't perform as well as it might. if you have a handy dandy talking meter, you could test the

Dear Max and list members: The best ham antennas I have ever had were full-wave loop antennas. On 75 meters, the square was roughly sixty feet per side, with four sides. I constructed the loop with number 14 copper-clad steel wire, with a matching one to one transformer at the corner and
