Topband: Fw: Inv-L joy

[Arthur Delibert]

Tom --

Try the trick of taking the outer sheath off a few feet of
 large diameter coax and slipping it over the rope where it crosses the 
tree limb.  (It may require some duct tape to hold it in the right 
place.)  The ones I've done like that have lasted for years.

My L came down recently after well over a year of backwards and forward over the branches, so now my annual maintenance will include lowering the antenna, shortening the halyard at the top end to allow a fresh section of rope across the branches.
