[Elecraft] RF in the Trees

[Charlie T, K3ICH]

The professional "Arborists" use a cloth or leather bag filled with lead 
shot and something called "tangle-free" line or similar to throw up in a 
tree so that they can pull up a supporting rope for tree trimming etc.  From 
what I've seen, the bag is about the size of a tear drop shaped golf ball. 
The idea of the shot instead of a solid weight is to make the bag less 
damaging if it hits your house (or window) on the way down.

I have a neighbor who's son is an arborist, so I've watched him on several 
occasions.  It DOES take a bit of practice, but the line never seems to get 
tangled.

I tried this with a few lead fishing weights on some thin nylon line and it 
was a disaster.  The secret is to use a thick enough line so that it won't 
spin around itself and (mysteriously) tie itself in a knot way up in the 
tree.
