Jim: Phyllistran will abrade very easily. Even used as a tower guy you
should keep it away from tree limbs etc. Good quality rope will do the
The best way I know is to run a catenary line between two trees with
enough slack to handle the sway from the trees and have a good pulley in
the middle of the cat line. Pull up the antenna using the mid pulley
and good rope. Very little problem that way. I have a cat line of 5/16
Dacron rope running from tower top to a 110 foot Tulip Poplar. I have
two pulleys on that line; one for a delta loop and one for a 160
Carolina Windom. They hardly move in a stiff wind.
I have the vertical end of the cat line coming down the tree tied to a
big log chunk....weighs about 100 pounds. It does move an inch or two
once in a while...but no rope breakage yet and on 4th year up.. Rope
goes over a high limb without a pulley etc. Hope this helps. 73 bob de
