[Lowfer] rx loop copuling

[Dexter McIntyre W4DEX]

I recently strung up a receive loop about 400 feet from the shack in the 
woods.  I have 75 ohm coax running partially underground with remainder 
on the ground to the antenna.  The  antenna is a single turn of WD-1 
army field wire, two twisted wires connected in parallel.  It's is in a 
delta shape with apex about 45 feet high, horizontal run about 8 feet 
above ground and 125 feet long.  Coax runs to center of horizontal 
section.  So far I have found no way to couple to this loop to make it 
receive worth a darn.  Any suggestion for me to try?
