[TowerTalk] [Bulk] Re: Phillystran

[Roger (K8RI) on TT]

Bent booms with Saddle clamps on the boom would be from either over 
tightening, or insufficient boom material.
Bent booms from saddle clamps on the truss begs construction 
techniques.  Even the small Phillystran is good for a 1000# plus and 
with the recommended 3 clamps per termination should have no creep 
unless the boom is extremely heavy.  The larger Phillystran of 4,000 and 
6000# test would/should be used with Big Grips(TM) and turnbuckles
