No sure if this has been addressed yet, forgive any repeating.
The "Scientific Atlanta," was marketed for radio stations, and usually installed back in the 1980's to receive 139W in fixed position. Unique in mount, unique in how it's polarity was chosen for the LNB. The mount is MASSIVE, and usually sat on about a 4 x 4 by at LEAST a 4' pad for stability. Many stations still use these, in fact WE do, but now it's aimed like most other stations, at 105. I can't speak to it's 2 degree compliance, but the engineering is amazing. There's a rod that comes down through one LNB support strut that turns with a screwdriver to run gears which flip the LNB from one polarity to another. With some engineering you could put a modern LNB on it, and as others have said, a "fixed" dish is great for 99w, 101w, 103 w, any C-band bird with enough open feeds to add to your viewing experience. You will, however have more engineering to reinstall
this model than in a standard "pole mount." The Scientific Atlanta units are VERY stable, and have multiple lockdowns for horizontal and vertical position so you won't be drifting, that's for sure! They'e very HEAVY but can be disassembled...plan on quite the project. Given your situation, not probably suited to your intended use, however...for SOMEONE...not a bad thing for a "fixed" install that will last probably forever with almost no maintaining, except maybe some painting now and then, and some treatment to nuts and bolts on the mechanisms. Pictures attached of our re-aiming this year for network radio..
