If you use Phillystran, it may be wise to have a EHS guy already made up
that could replace your longest Phillystran guy (or any of the shorter ones)
if they get damaged by abrasion or falling debris.

Subject: [TowerTalk] Temporary guys
Howdy, TowerTalkians --
I just read a portion of the ARRL tower book where the author recounts
an episode where the temporary rope guys holding the bottom sections of
the tower stretched so much that he found himself laying on the ground with
the tower laying on top of him. Similarly, W2GD had the same thing happen
to
him. In neither case was the climber terribly injured but they were lucky
to fall onto soft ground.
If you're going to do something like this (the use of temporary guys
has its applications) and use rope, the best thing to do is to use a
'trucker's hitch' which gives you a 2:1 mechanical advantage and provides
much
more tension on the rope to minimize any stretch or failure.
In the book, the author says he only uses steel temporary guys now -
lesson learned. But using a trucker's hitch will make using rope guys
viable
and safe.
