[TowerTalk] Guy Wire Cable Clamps

[Roger (K8RI) on TT]

A simple suggestion that makes serving much easier.  Use wire ends 3 to 
6 inches longer than required. when the required turns are wound flat, 
just cut that wire as short as possible and force the tip flat with a 
pair of Channel Locks
No it doesn't make serving easy, but relatively speaking, it make it far 
easier.
