You are correct that the Steppir  puts more torque on the rotor and mast. I 
think any of the rotors you mention will work for your 3el. But they should 
be controlled by a Green Heron control box with the ramp-up and ramp-down 
feature, it makes it very smooth.

I have a US Tower MA-40, a MARB and MAF. I also have a SteppIR 3-element

beam. What rotor do I need?


One knowledgeable person about rotors has suggested thatSteppIR's put a

lot of torque back and forth on rotors. He thinks a HAM-IV will getdestroyed
and a t2x is marginal
for the 3 elSteppIR because of the 16' boom and 36'

long elements even when mounted inside a
tower on a rotor plate.? He wonders

if a t2x can handle the rotation of the MA-40 tower and the SteppIR as well. 
He
knows of many people using the MA-40 rotatable tower as I? want to do, but, 
they
aren't adding a SteppIR on top. He suggests abigger rotor or?smaller 
antenna.

.

I know some people who are using a HAM-IV to rotate a MA-40 tower, but, they 
do
have smaller beams. Please let me have your experiences and suggestions.
