[TowerTalk] fiberglass guys...

[Gary.Stone@med.va.gov]

Hi TT,

Well, my .02 worth.   I have an 80 foot tower with Philly.  I have noticed
some (but not much) stretch.  However, I have a brochure from the company
that indicates there will definitely be some "relaxing" happening!  They
say:

"Tension HPTG-I assemblies to approximately 15% of it RBS. Guy tension will
automatically relax to approximately 10% RBS..."

So, the company claims Philly will 'relax' about 5 but I don't think mine
did that much - but it did a bit and I tightened it up a couple times after
construction but have not needed to do so after that.

Gary, N5PHT

I agree with Bill .. I have never had any qualms about monkeying about on a 
Philly installation ..  I did not care too much about the mid-8Øs 
self-potting process, but on the other hand I never heard of anybody with 
failures.  As to stretch ... never have seen any that was noticeable. 
Though I never used them myself, I have seen an installation with fiberglass

insulating rods on the tower,  I often wondered how that worked out long 
term.  Myself, I would stick with the EHS.
