I get a lot of noise from my random wire antenna. It transmits very well but
is very noisy in receive. My neighbor put up a 280 foot loop antenna which
he feeds with ladder line. He feeds the ladder line from a 4 to 1 balun to
coax. The coax comes from a tuner. His setup performs very well on all bands
down to 75 meters. I went over to his shack last night and listened to his
receiver on 75. I was really impressed with the lack of noise. I can safely
say the difference in noise was profound. He has this loop surrounding his
house at a 30 ft. height. It is arranged in a square.

Has anybody else had this experience with loops? It looks like I have room
to put up a triangular loop. Will this work as well?

Can I use the same tuner I have now and just feed a coax into a balun. Or,
should I put the balun in the tuner and come straight out with ladder line?
There is a lot of room in this tuner. It is an old remote controlled tuner
surplused from a ship.
