I had a Telrex rotator which was basically a reversible A/C motor connected
to a gear box by a chain. It used a selsyn for indicating direction. If I
were to build one I would use a DC motor and a more modern controller such
as the one made by Green Heron. If you have some fabrication skills I think
that you can make a very heavy-duty rotator for a reasonably cost. Most ham
rotator are toys. Look though a Grainger catalog for motor and gear pricing.

I have been intrigued with putting together my own antenna mast rotation
system and wondered if anyone has any info on using a rack and pinion gear
type system in conjunction with a linear actuator. If the rack and pinion
turns out to be too expensive, my second choice would be a chain drive with
the linear actuator.
Thoughts?
