[TowerTalk] Feeding a Delta Loop

I am interested in your antenna. I have a 120 foot tower and an inverted
vee for 160 at about 100 feet in the center. I wonder if that delta loop
would give me better performance? Every time I do the math, (160 M X 3 feet
/meter = 480 feet/3 gives me 160 feet on a side and it doesn't seem to fit.
How did you get it to fit. Do you have some kind of a coil to shorten it up
in the legs?

Stu I tried just to reply to you but everything I tried ended up here....
but here is my experience... I have a full wave delta loop for 160 hung off
at the 90 ft level of one of my towers.. sort of a tri-angle with the long
side at the bottom about 8 ft off the ground. The whole antenna is tilted
about 20 degrees from vertical and I feed it at the near low corner with a
4:1 balun... works like a killer and has great bandwidth. Bandwidth is about
100 kHz for 2 to 1 points and works great for transmit DX but not the best
receive antenna in the world. My 2 cents... Cort K4WI
