[TowerTalk] HyTower guying

[Patrick Greenlee]

There is an alternative to Big Grips, which uses epoxy to form an enlarged 
end on the Phillystran to terminate it.  I don't think making a fairly sharp 
bend in Phillystran is conducive to a long service life. Bending Phillystran 
around a thimble and clamping could cause problems, especially if the radius 
of the thimble is rather small. Historically one of the engineering 
challenges with aramid fibers and their kin is their being easily broken if 
flexed too far.

Just 3 days ago I guyed my Hy-Gain Hy-Tower at the top (24 ft level) of the 
triangular tower portion using Phillystran and Big Grips (work like Chineese 
finger grabbers.) It is installed atop a 36x76 metal bld where the wind is 
stronger than ground level and ground level gets interesting winds (South 
Central Oklahoma at the heart of Tornado Alley.)

Please, no clamps.  Spend the money for big grips.
