Randy,
I have 15 Beverage wires that average about 900’ long. About 2.5 miles of wire.
All the wires are in dense, old growth forest.
I have trees falling ALL the time. Every wire has a counterweight concrete
block pulley system to prevent breakage.
When a tree falls on a wire (about twice a month), the wire does not break, and
a quick trip with the chain saw to remove the tree recovers the wire.
You may not be a “video guy” but I made a YouTube that shows the detail of how
I install it and how they work:

And here is a short video showing it in action:

Also, for those that have larger Beverage installations, this video explains
how I use my antenna analyzer to sweep my wires at any time (even remotely) and
by comparing the seep to saved files, I know if a wire is down.
This is NOT a trivial problem. With my Beverage field, to walk and check all
the wires, I would need to walk about 8 miles through heavy bush! This would
take the better part of a day.
Before a contest, in 5 minutes, I can check all 15 wires and know if there is a
tree down or broken term or feed.
