Current system is Dish network receivers, DP 301, and dish 500 dish with dual LNB. I pickup a Dish network Oval dish with 3 lenses. And the LNB has on it DP Plus. The oval dish has a Dual LNB like my dish 500, and a third lense seperated from the other lenses. 00 0. (Just like the 0's.) I tried to hook up the oval dish to my receivers but could not find any satellites. It looked like it found 109 but didn't acquired. I double check the settings on the dish and moved it around but still couldn't find any satellites. So the question is, is the oval dish that I acquired compatibly with the dish network receivers, DP 301, that I current have. If so why can't I get a signal.
