The 72 degree slot that VOOM will use is KU FSS. FSS slots tend to be somewhat lower power and reside every two degrees--unlike DBS where slots are every nine degrees--thus a larger dish is required to distinguish between them. There are KU FSS slots at 70 and 74 degrees that would make a smaller dish for 72 degrees impossible.20x35 seems SO freaking huge for a 11 degree spread. DirecTV does three satellites at 101, 110, and 119 with a 24" dish. Dish does 110 and 110 with something about the same size.
