Delta loops show marginal gain over a dipole (1.1db), and are much more of a
pain to erect. As far as noise no real proof that is true. And one more
thing, feeding with 1/4 wave of 72ohm is more voodoo engineering you find here

Use a telescoping fiberglass pole.
They don't have to be very high.
25 ft. is high enough if you make the horizontal bit a little longer.
That still leaves about 7 or 8' under the antenna so that people can walk
under it.
Scott (W4PA) sells 40' poles. One of those would be perfect.

I'm sure Gary they are the best antenna for the dollar, but not enough trees
here for support. I was raised on a farm & my late father, W4PFP & elmer,
had some serious wire antennas. I miss the real estate, but not the
farming.

Reed,
I had a 80M Delta loop up for quite a few years. It worked extremely
well. Very quiet. It was fed in the corner with 75 ohm coax, then 50 ohm to
the shack. My matching piece of 75 ohm coax was abt
46.5 feet long (1/4 wave x velocity factor of the cable). I'd put another up
but all my trees have grown up.
