The recommended tension is 10 percent of the guy rating. If you are using
1/4 Phillystran, it is likely rated at 2100 pounds so your tension should be
about 210 pounds.
First, plumb the tower using moderate tension (50 lbs or so) on all guys.
Start with lower guy. You can do this with a long carpenter's level, or
using a plumb-bob. Next, turn each turnbuckle an equal amount until at
desired tension. You will note that tensioning one guy automatically
tensions the other two at the same level. Double check the plumb when you
are done.

Subject: [TowerTalk] Questions about Tower Maintenance
Hi to all,
This is N5PHT, Gary. I am looking for some very specific steps to adjusting
guy wires on a tower. I have a RG45 up 80 feet. It is the pier / pad
construction. I would like to be able to adjust the guys with step by step
instructions (for dummies like me). What guy do you start with, etc. I
have a handheld device to measure the tension and I have read that the
tension should be around 10% (which would be 650 lbs inch I believe). The
installer came back and tweaked things a couple times after settling but I
would like to learn to do the maintenance myself. I am using Phillystran ¼
inch and the tower is guyed in two places with 3 guys per common
installation.
A tutorial on this type of tower maintenance I would be great? Also, any
other maintenance instructions?
I had lots of loading questions, etc. early on and now the tower has been up
about 2 months and doing well. Thanks for all the help from the group. It
has a 40 foot Optibeam and a smaller Force 12 (with about 32 sq. feet
total). The Optibeam and the Force12 are about 12 feet apart. I had some
rotator problems but I hope that is now worked out all ok.
Gary Stone, N5PHT
