Does Rohn really make a base plate like this? The only one I'm aware of
for 25 is the pier pin base, which has one hole in the middle (more or
less). For a guyed tower, the base requirements are really minimal -
sufficient resistance against downforce and a little for lateral movement
of the base -- in fact, some analyses suggest that the pier pin, where the
base is free to tilt or twist a little, may be the best from the standpoint
of distributing stresses (or anyhow, avoiding a "hot spot" at the bottom.
So maybe all you need is a pier pin and 1 8-inch hole.
