It's not just the guy wire and anchors you need to worry about.
You are also limited by the compression strength spec of the
tower legs when the wind blows in the worst-case direction. As
the anchors move in, the compression load goes up when the wind
blows. Rohn 25, for example, is specified at only 8430 pounds max
per leg.
