Go to this site:
http://www.prosistel.net/home-e/default.html
and on the left there is a rotator comparison link. While this is the
Prosistel site, the table shows the Orion 2800 along with a bevy of other
rotators and their specs. For a big antenna, I'd go with the Prosistel
PST-71 or a prop pitch.
