[TowerTalk] pull lubricant

[Steve Maki]

Dick,

Great question. I think it's a bad idea to pull air dielectric coax 
through 90 degree bends. You are asking for trouble. I've recently run 
up against two situations at broadcast stations where it was done and 
now 10 years after the fact, shorts have developed at the bends. Kind of 
like the 8214 center conductor migration problem.
