[TowerTalk] Guy recommendations for push up pole

[Roger (K8RI)]

There are several possibilities but most synthetics degrade rapidly in 
sunlight. Nylon stretches like crazy..*initially*, but after it's been up 
for a while it becomes a good guy for light loads. I use 3/16" on my AV-640 
vertical.  After the first week (or a good wind) you'll find the stuff has 
stretched by feed. The next time, it's only a few inches and after a couple 
of months it works well.

OTOH I purchased 500 feet of HPTG12001 Phillystran from Texas Towers. At 45 
cents per foot it's not all that much more than poly or nylon, has very 
little stretch, rated for 1200# breaking strength, about the same size as 
3/16" wire rope, and has about 3X the strength of the wire rope. So, I've 
decided to use the stuff in place of the nylon andpoly rope I've used in the 
past.

BTW you just use cable clamps and a thimble on each end for the HPTG12001 
instead of the "Big Grips".

Hi Everyone,

I'm posting this for a friend, Mike WBØSND:

  I'm putting up a temporary beam installation and need to know the 
appropriate kind of rope to use for guying the mast (poly, nylon, or ?).

  The installation is a Rohn push up mast which is in concrete and bracketed 
to the facia board on the house.  The mast is going to extend about 8 feet 
above the roof line (a total of 30 ft) and will have a Ham IV rotor and Hy 
Gain Explorer 14 on top.  This is just a temporary installation to get 
through the winter.  In the spring, I will take it down and put up a 
permanent tower.

  So again the question is:  What kind of rope should I use for the guys?

  Thanks to all.
I appreciate any assistance you can provide him.

73,
