Hi, a newbie here. Currently we only have SD receivers. We have a dish pointed to 101 and another to 119 (LOS issues) I want HD but I don't know what is the best setup. Is it possible to combine the signal from a SL3 with the signal that comes from a 119 dish? (What's the difference with the SWM version) What multiswitch I need for do that. Currently we have 4 SD receivers, thinking in switch 2 to HD.
