Ok I took some measurements - I found them odd. From edge to edge across I get 48" top to bottom it is 52". I placed it flat on the floor and it has no warp that I can tell. No markings could I find, the 2 support arms and lnb arm screw in on the edge of the dish. I do have all the mounting hardware but the pole mount part I have to remove from my 10' C dish set up, not that big of deal but it's some thing I would have to work on (you would have to see it to understand). So let me know if you want it, and or need photos.
