See the attached files, I got them all under 30 KB, hope they upload.
The smaller dish is 10 ft and the big one is 15 ft. They are both working just fine for us.
9261 looks like a Comtech 5.0m on a polar (ring) mount, just like we have at my employer. The smaller one might be a Comtech 3.8m but there’s not enough detail to tell. As was posted already, see if you can get a frontal and rear view picture of each.
In the meantime, I’ve posted some manuals for some of the dishes we have here. We have both the 3.8m and 5.0m Comtech dishes here, along with a Prodelin 4.5m dish. (I’m skipping the 6.3m RSI Vertex dishes because I figured nobody else on this list would have them, but if someone really wants the specs let me know.)
