For those with trees and big saggy 160m dipoles:
The best (only) way I have found to keep a dipole halyard running smoothly
over or up a tree is to use stainless or galvanized steel halyards, straight
over the top of the tree. Pulley systems inevitably get stuck in trees and
even the toughest Dacron or nylon will fray. Nice old greasy guy wires
slide well!
vk6vz say non-steel guy rope always break when new country on.
My 160m inverted-U dipole is now held up by a 30m (non resonant!) length of
old galvanized steel tower guy, with a 20m length of Dacron attached to its
end. When the dipole is pulled into place, there is no Dacron rope in
contact with any part of the tree (so no rubbing/fraying).
Only thing to watch out for is if there is a lot of movement in the tree,
the steel halyard may rub through a branch or two... Watch out below!
Very 73,
Steve, VK6VZ
