Thinking about trying a K2AV folded counterpoise and using a nearby 
chainlink fence as the counterpoise instead of the
2 poles that contain the folded counterpoise.

My idea is to use the fence pole in the center with the white arrow pointing 
to it and tie the bottom side of the isolation xfmr to it
and have it contained in an enclosure tied to the metal pole with tie wraps 
or plumbing hose clamps. I would place an 8-10 foot fiberglass mast
thru the enclosure and come out the top along the mast with the main 
vertical (hat) radial , then dog leg it on an angle thru the treeline to the 
north-
west as per this picture:

The purple line would be the 120 feet if wire for the "hat" part of the L.
Each length of the fence is about 130 feet from the center where the white 
arrow marks,
and each corner has an identical pole, likely in the ground a few feet 
secured with concrete.
I hear burying counterpoise radials with monopole antennas helps alot, so 
thinking this would stand
a good chance to serve as a good counterpoise.
