Well, of course you'll get different opinions from different people and this is just mine.� Some folks think the antenna will set the tree on fire!

I've had both insulated and bare wires in contact with limbs, leaves, etc.� Hard to do otherwise on my lot if you want an antenna of any length.� Sometimes the limbs or trunk will even grow around the wire.� I guess it's possible there's some signal loss, but I don't think it's significant.

On VHF and FM broadcast, there's no doubt that summer foliage degrades reception in fringe areas.�� But being fringe probably means the signal is passing through *lots* of vegetation on the way.� I haven't seen any authoritative info to say that this is an issue at HF.

My antenna wires touch tree limbs all the time.� That shouldn't cause you any problems.

Does it make a difference if the wire is insulated or bare when it touches trees?
