How important is it for the top part to be led away at a right angle?
I was considering running it vertically 80ft, then about 25 feet at a 45
degree up angle and 25 feet at a 45 degree down angle, over the top of the
supporting tree.
That shape should work just fine, BUT -- the end of an inverted L is a
high voltage point (VERY high voltage if you're running an amp), so it's
easy to get arcing to the tree. I had a 160 dipole up for several years,
and the first rigging had one end in contact with foliage of the tall
redwood that held it up. When I took it down for maintenance, the
insulation was heavily scorched.
Another suggestion. Do you have skyhooks that you might use to turn it
into a Tee? If you can, it will work as well or better than the L. Both
configurations are simple ways of providing top-loading.
Bottom line -- run it through the tree with caution. It will work, but
things can go wrong. :)
