Don-
I use your technique here on tall trees. Besides minimizing abrasion, the
pulley allows the treetops to move in different directions in the wind
without breaking wires! It's fun to watch the counterweight rise and fall
along the tree trunk. At my place it might move up and down 15-20 feet in a
big storm.

Subject: Re: [TowerTalk] Tougher antenna rope
Pete,
Try the following:
1. Place a line over the tree as desired 2. Attach a rope with a pulley at
the end.
3. Run another (support) rope through the pulley.
4. Raise the pulley to the desired height.
5. Using the support rope, pull the wire antenna taught.
6. Do NOT tie the support rope to a fixed point, but, rather, attach a
heavy weight to it to keep the wire antenna taught.
This will keep the rope from being abraided by the antenna moving in the
wind, or loaded with ice.
Good luck
