Bob,

I intend to use Rohn 25 for a similiar setup as yours.  I feel that the Rohn 
25 is more than strong enough to support this array but do to the height you 
are planning, I would still attach guy ropes.  I am only looking at going up 
about 30-35 feet with the tower attached to the eve of the house and I will 
still use at least one set of guy ropes do to the possiblity of hurricane 
winds.  My main concern is the weight on the rotor I will be using (HamIV)? 
I will probably end up using some sort of support bearing to ease the load 
on the rotor.
