Hi, Alex --
IMO your options (in decending order) are:
Prop pitch -- will rotate a house and utterly reliable
Orion 2800 -- a pretty good heavy duty rotator with worm drive (no brake
required) and splined output shaft
Create RC5B-3 -- good comments from users and it has good sturdy gears in the
transmission
Yaesu G-2800SDX -- may be suitable but lacks the rotating torque of above
rotators and uses the aluminum mast clamps that are easy to overtighten
and break
The only other HD rotator that I've seen was in an Italian ham magazine
and looked like an industrial motor and transmission. There are also
commercial rotators available but are expensive.
BTW, you may want to subscribe to TowerTalk -- the tower and HF antenna
reflector. This is the kind of topic that may be more suitable for it than
the CQ Contest reflector. Send a message to towertalk-request@akorn.net with
subscribe in the message and you'll be all set. It has many knowledgeable
people that can provide valuable information. See you there.
