[TowerTalk] Phillystran Abrasion Resistance

[K9MA]

Unfortunately, one guy wire goes right between two closely spaced 
elements, so rotating the antenna won't help. There's no other way to 
avoid contact, though it will only occur during high winds. I did do a 
crude abrasion test with a smooth drill bit, and concluded that the 
jacket is very tough.
