I have a Dish 500 (2 LNBs) pointed at 110 and 119, and a dish 300 pointed at 148. The Dish 500 and 300 go thru a SW21 to my 6000 receiver. I tried pointing the 300 over to 129, but can't seem to locate 129. Doesn't help that the nimwits that installed the dish with the mast crooked so the elevation markings are useless. Anyway I'm wondering if I need to just keep searching or something about my setup/equipment is an issue.
