Brett,
Everything I know about towers I absorbed from the towertalk reflector over
the years. Someone mentioned 80 percent. That is the number used by Rohn
and whoever took them over a few years ago. For a 100 foot tower, the
anchor points should be 80 feet out. 50 foot tower, 40 feet out. The
closer the anchor points are brought to the tower, the steeper the angle,
and the more compressive / downward force is put on the tower and it's
base.
I also understand that while some crank-up's are designed to be guyed, most
are not and it's not wise to guy one that is not designed that way.
Whatever you do, do it safe.
73, Steve KW3A
