Loop Antennas
The loop is a DC short and is very quiet. You can also feed it with a
quarter wave section of 75 ohm coax using (quarter wave length x Velocity of
coax) as the length of the matching section.
Good luck,

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.
