I was hoping someone would recognize the dish and might know if it was worth pursuing. At 10' it's too wide to bring home on top of my pickup truck bed. So I would have to rent a cargo van and carry it diagonally inside. And since I don't know if its true or warped, I would have to go there twice -- once to string test it and then again with a cargo van if its good.
The seller wants $100 and does not have the pole, the mount, or the struts.
At this point, without any more to go on, I think I will let it sit. Maybe eventually someone here will recognize it.
