[TowerTalk] Long Wire Sag

[Don]

Nicking copperweld was mentioned. Amen! Had some for a 160 up here on 
coast and the little salt air gremlins cut through the exposed wire like 
butter and kerplop!.Stuff is strong but sure not for coast areas, at 
least not here where I am. I'll take the copper stretch and deal with it 
as needed.
