Hello Gregg, Maybe this will help? You may already have this info but just
in case.
Rohn give 60% ~ 80% as per tower wind loading. ( I've never trusted wind
loading specs because you never know what wind gust you will encounter and
or what angle the wind will hit your above tower load). With no above tower
load you should be able to use the lower percentige figures depending on
your location and usual max wind estimates.
How this helps...

Sorry about the first post that may have gone out to the wrong address and
spelling was never my best subject.

Subject: [TowerTalk] Rohn 25 guying question
I am planning to put up 130 ft. of Rohn 25 to be used as a 160 meter
vertical. There will be no antennas on this tower. The Rohn spec for guy
anchor points is 80% or 104 ft.
I am looking for some guidance. Getting 3 guy points each at 104 ft. from
the tower is going to be challenging due to terrain and property lines.
Are
there any guidelines for anchor placement for a tower that does not have
to
be subjected to additional loading from an antenna?
Any feedback is greatly appreciated.
