I pickup 110, 119, 129 with a DISH 500 so that is three slots at 19 degree of spacing. I think a DISH 500 is larger than a DISH 1000. It may be able to go slightly more than that with the spacing. If a 20/22 inch dish like a DISH 500 can do 3+ orbital locations then a DISH 300 can probably easily do 2-3 orbital locations as well. I have not tested DISH 500 to do 4 orbital locations yet. I could hookup 101, 110, 119, 129 to see if that works on a DISH 500. Has anyone else tried that? I think it will work because the two other slots that I have are offset on one side of the dish so I should be able to pickup more slots on the other side of the dish plus one centered in the middle.
