Well guys, I was able to get the dish down by myself. I found out that it is indeed a SAMI. The logo was faded out on the feedhorn cover.
I have a dilemma though with getting the dish home. Right now it's on its face. If you look at the pictures, you'll see the front and back plates the hold all four sections together in the middle. When I have the dish on its face, I can get to all the rib bolts themselves but when I try to turn the nuts on the back rib plate, it just turns the whole not and bolt because of the rust. I've sprayed with PBblaster a lot, but I really need to get to both sides. On the other side the bolt head is flat. I'm not sure what to do at this point. I want to get this thing apart. Taking it home in whole is not an option for me. I was thinking I could crawl under the dish and take out the screws for the mesh on one of the panels, which would then allow me to get to the nut and flat head bolt. Once I get one rib panel free, the other three would be a piece of cake. Should I go this route or is there another way?
Thanks,
