[TowerTalk] Durability of Mastrant rope

Was the antenna installed with pulleys and a weight on one end?  Any 
antenna rigged between trees without that method WILL be on the ground 
when the wind blows hard.

I use Synthetic Textiles antenna rope sold by several ham vendors. It's 
good stuff, but the outer jacket of the 5/16-in rope eventually frays 
and breaks where it goes through the pulleys, and must be replaced. I've 
gone to the 7/16-in rope for my high dipoles between redwoods.  In this 
rope, the strength is the interior white rope, while the black outer 
jacket protects it from UV.
