[TowerTalk] Rotor Selection Advice Wanted - Heavy Duty

[Stone, Gary R.]

The ProSisTel I used fit my Rohn45.  I think they used to have the motor
repositioned but not any longer. But I have no idea for other towers.

Will the ProSisTel fit if the motor is repositioned?
I had to reposition the motor to get it to fit into the ROHN45.
