Bill, that's correct. But, most guying systems are only 3 wires on a 120
degree spread at 45 degrees from the anchor on the tower/mast. That
requires only 75 feet. A three wire system is a STABLE solution. A four
wire system is also a stable system.

BTW, I used to have a Rohn 25 system at 50 feet. Rohn recommended double
guying. First level at the 30 foot height. Second level just below the
rotator platform. Point I'm making is that one set of guys at the 50
foot level may not meet Zoning and Insurance safety requirements.

With four guys the distance between any two 180 degree opposing guys will be 100' at
the base level. That is why I said that four guys at 45 degree angle at the top of a
50' mast will make a square at the four anchor points and that square at the base
level is 100' on each side. I am thinking that 30 degrees at the top might be fine for
my project in which case a smaller square.
