You say 1/4 Phillystran and 650 or so tension, which would be 6500 lbs rated
strength. My Phillystran is 6700 lbs rated strength but quite a bit larger
than 1/4 inch. With the black plastic jacket it looks to be about the size
of RG8 coax. My Loos gauge will not work on cables this large. I also have
1/4 EHS leaders on each guy and measured there.
I have my guys set at about 500 lbs according to Loos. This takes out most
of the droop in the guys. There are 4 guy sets. The tower feels steady up
at 150 feet. That's good enough for me even though, according to Tom's
report, the actual tension may be near 330 lbs.

Subject: Re: [TowerTalk] Loos Tension Gauge
Wow - this is interesting. Can we get a definite answer on how to measure
Phillystran? That is a real difference. I have 1/4 Phillystran and using
my Loos I have been shooting for about 35 (650 or so - which is 10%) but if
it is inaccurate I may be tightening too tight?
I wonder if the Phyllystran company would have a suggestion as to a proper
device to measure tension with their material?
Also of interest is that I am (and probably others also) actually putting
the Loos device on EHS 1/4 inch because the first 15 feet or so is EHS as is
recommended. I don't think I would have a tall enough ladder to check the
Phillystran itself but that would be interesting?
