[TowerTalk] Orion OR2800P

[Chuck O'Neal]

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.
