[TowerTalk] Phillystran suppliers

[Pete Smith N4ZR]

I recall back maybe 20 years ago that PVRC members put together a group 
buy of fiberglas guy rod from the manufacturer.  Instead of risking used 
Phillystran, or paying $2.05 a foot from DXEngineering, for such a  
major project you might get together with others and explore doing a 
bulk purchase from the manufacturer.  The stuff might be available in 
1000-foot rolls for a considerably more reasonable price.
