Here in Texas where it gets dry, we usually run Phillystran for most of a
guy to a turnbuckle and for the 10-20 feet nearest the ground run wire.
Phillystran will melt in a fire.

Subject: [TowerTalk] Phillystran Top Guys
I am in the process of putting up a 100' stick of Rohn 45G. Originally I
planned on standard Rohn guying - 3/16" for the bottom two guys and 1/4"
for the top - for Rev G. Does anyone have experience in leaving steel for
the bottom two guys and Phyllystran on the top? How about running 30' of
Phyllystran at the top end of each top guy - like an extended insulator? I
am trying to minimize interaction with the various wire antennas I'll hang
from the tower and keep costs somewhat under control. I'll have a 3el/40M
option SteppIr for openers, but may change that at some point. Obviously I
am going to play with a bunch of wire - dipoles, inverted Ls, slopers,
etc.
On a different note, another ham, WB9EDL, and I delivered some used 45G
sections to the Rohn galvanizing facility today - they are called AZZ
Galvanizing in Peoria. The cost should run approximately $45 per
galvanized 45G section. I recently took down 90' of 25G that had been up
for 34 years. It was a used tower when I purchased if from a local ham
and I hauled over to Rohn to be regalvanized when I bought it. The tower
was in great shape when I took it down a month ago, just beginning to
show some brown staining in places; the leg interiors were still shiny
bright. Re-galvanizing is an inexpensive way to rejuvenate old steel
towers. AZZ is also redoing my guy brackets, equalizer plates,
stand-offs, etc, basically anything except threaded goods - bolts, nuts,
turnbuckles, etc.
As long as I am posting - I recently helped put up 50' of 45G for another
local ham, AB9M. We had to spend quite a bit of time cleaning excess
galvanizing from new tower sections - the inside of the leg joints. We
did a trial fit of all sections on the ground and labeled each mating end
of the towers so that they went together the same way in the air. We did
50' in a single after noon. I did purchase the Yellowjacket tower tool
and it would have been difficult to get the sections together without the
leverage it affords in pulling tower sections together. Also - we had one
mismatched set of legs that would have been a real trial without the leg
aligner part of the tool. The tool really worked well for us.
Original question - any experience mixing steel and phillystran?
Thanks,
KeithAC9S
