[TowerTalk] self-supporting rohn 25g??

[Red]

I wouldn't build on a guess if that tower is placed where it might fall 
on something valuable.  It isn't very difficult to calculate dimensions 
for a base that will resist a specified overturning moment.  The simple 
calculations assume poor soil characteristics and other simplifications 
and result in a conservative design.
