I have heard of using a tree as a Rx antenna but not in what context
could have been in one of the April issues,,, 
there isa fine line where an E field antenna becomes a long wire
I have my Amrad Probe mounted over an FM and UHF Tv antenna on a roof
tower
no RF input filtering and no Intermod problems with about a 3 Ft wip. The
antenna uses a separate
ground . The roof tower is tied into the other antennas ground field.
Only problem is interference
when the VCR connected to the TV antenna in on. Then there are some birds
on LF
Methinks next year one of the non tuned loops Ala Mitch may be in the
works

interested in your results
