This system works fine until our winter storms kick in. Often, during

ground with no way to get the insulator back down short of hiring another
costly climber.

Does anyone have any solutions to this problem?


Hi John,

From Rain City (Seattle). I did this in a Maple forest. I did mine
with pulleys top and bottom with a continuous loop like a flag pole. I
then passed up another pulley on that loop for the runner holding the
wire antenna. Then I made sure it would break at the wire connection,
not the rope. The continuous loop always gave me access to the pulley
that the antenna rope passed through.


Just be sure the two ropes coming off the pulley don't gett tangled up with
each other. Mine did

I used a two liter bottle of
water to ballast and tension the wire pulley system.


This also works. As the tree sways back and forth, you don't want the wire
to keep moving. I brought the fixed end of the rope some distance from the
tree, and fastened it to half of a cinder block laying on the ground. The
cinder block will move to give you slack, but not move back when the branch
moves in the other direction.

Think FUSE. Choose your point of failure, don't let it happen.
