I run the following antennas in some pretty serious forest, and I get great
results with them all:


   - 160M Inverted L with elevated radials over Pine trees.  The tree is
   about 90ft tall and then the insulated wire loops over a branch
   - 80M Vertical also will elevated radials (the rope goes over a branch
   at 90ft)
   - 80M V with the apex at 70ft over a single Pine tree
   - 132ft Windom supported at both ends with a center support over
   hardwood trees at 60ft.

In all cases, you have to be created to allow for flex as the wind blows.
 It has taken some trial and effort, but you'll figure it out by watching
things move.  Yes, you'll break it a few times, but eventually you'll come
up with a solution.

The worst case for moving resonance is the Windom, but that is easy to deal
with.

The 160M vertical varies is resonance point, but that is due to the ground
conductivity changing from winter to summer.

As I mentioned earlier, just do it.  It will work.

I have used both air cannons and my quad copters to drop my lines in place.
