[TowerTalk] Wires in trees

[Steve Boone]

Thanks to all for the input on my 'wires in trees' problem. I was
previously aware of the interactions - signal wise and was focussing on the
likelihood of arcing potentially causing a fire hazard.  I received some
inputs suggesting that my concern was not unfounded.

Given the serious compromise that my proposed antenna would be, I will
investigate loading my tower for 160m. I have a rotating antenna at the
midpoint (30') of the tower so it could be interesting stringing the
matching wire.

Thanks again for the advice.
