Am giving thought to putting up a long wire loop antenna. A rough pace-off of the backyard seems to provide suitable tree locations allowing for about 540 feet of wire - not as much as I'd hoped for. More study is required. Existing trees are randomly located, so the enclosed loop area will have an uncontrolled irregular shape. But here's my (probably) dumb question. If using common, solid, home electrical wire (#14 or #12, which I have a good supply of), is it OK to run the insulated wire directly through the trees, over branches and touching leaves? Running through (or better yet - around the outside of) the trees will allow for a longer wire run, versus suspending the wire on insulators away from the tree canopy. But will that cause impedance problems when it rains, or when the tree bark eventually rubs through the wire insulation, or with propagation nulls due to limbs only a few millimeters away from the copper? Was hoping to use something like this for 160 meters, but probably not long enough to do anything except shoot straight up. I'll probably be lucky to get it much above 40 feet, especially with the droop in longer spans. I already have a multi element dipole for 80-10 m, but it's only about 25' high.
