Have utilized a different approach to this issue with good success.
The major problem with guy cable is that is will compress. Solid material
We installed 65' of 55G using a rigid guy system attached at 30' up and
anchored 8' from the tower base. The attachment point was standard Rohn guy
brackets. The rigid guy was a composite of galvanized pipe and couplers,
with a steel ear at the upper end, a large turnbuckle at the lower end
in this sequence starting from the top:
a) 1/2" flat steel ear with a hole to mount to the bracket
b) cut slot into 1.25" (I.D.) galvanized pipe
c) welded bracket ear into slot
d) added pipe as needed to reach close to the ground, using couplers
e) welded large galvanized turnbuckle onto lower end of the pipe sections
f) cut 1/2" flat steel anchor to go into the ground, with an upright ear for
lower end of turnbuckle attachment
g) drilled hole in ear for turnbuckle attachment
h) made fairly deep, round hole for anchor, set it into concrete
i) attached full rigid guy to tower
j) adjusted turnbuckles until the lower end could be attached to the anchor
k) attached lower end of turnbuckle to anchor
l) adjusted turnbuckle slightly until the rigid guy had no play
Climbing the tower after that was like climbing a tree.
Caution: cutting and welding galvanized pipe is dangerous and can cause
serious health problems.
All the steel parts were sprayed with cold galvanize afterwards.
The local inspector passed it without flinching.
Maybe this will provide an alternative thought for some installations.
Have a good day and 73,
