I'm in the middle of putting up a longwire antenna. One end is going

use a counter weight at my neighbor's end or try and fashion some sort

tree?

Neither. The "grappling hook" is waaay too marginal to depend on and
even an expensive marine block ('pulley') will eventually stop operating
without maintenance, to say nothing of somebody getting beaned by the
weights.

I would recommend a screen door spring at each place you fasten to a
tree. Go to a hardware store and find the biggest, beefiest screen door
springs that you can and then give them several coats of paint for rust
prevention.

I've been using this method for a 140 foot dipole (made from 14 gauge
insulated wire) attached to a pine tree at one end and a Norway maple at
the other end; its been up continuously since 1996.

tree - screw eye (or hook) - rope - spring - rope - end insulator
- antenna wire

You left out the last part of the setup.

His tree - screw eye (or hook) - rope - spring - rope - end
insulator - antenna wire - neighbors tree - insulator - rope -
hanging weight - LAWSUIT

Don't forget that last part.

That's why I don't use a weight. When I did the rope broke and the
antenna came down.
