Subject: LF: Low long wires

Ive only had partial success in low long wires up in Alaska= -=20 but my s/n failure was due to a 33Kv or more power line running parallel=20 underground just a few feet below the array for most of the way - that and= the=20 variable speed drives from the local water pumping station which the power= =20 cable supplied.
 
Im going to put "down" or it is "up" a=20 couple in a heavily birch wooded area in Alaska above moose antler height=20= and=20 they will be insulated off but supported by the trees. Ive just gaine= d=20 another painful acre so will have wires up to 100m in length or so - = I=20 have silt sand and ground water at around 12 feet in depth close in by a=20 freshish water (ice at the moment) lake.
 
So -=20 question what effect will the trees have decoupling LF signals in thi= s=20 type of medium (?) Z array given the travelling wave aspect? Does any= one=20 else have experience against open space wires .v. in wooded areas?  O= n=20 the TX side I see this without a lot of  clearing as another large TX= =20 loop experience - just too many tall decoupling signal Birch for=20 verticals at the moment.
