Hi folks newbie here, I have a dish 300 that has a dish pro lnb and a dish311 reciever, I also have a dish 522 that was given to me. I have heard from several people that a dish 500 loses signal easier than a dish 300, is this true? We get our programming from sat.110, I want to add locals and superstations. Would I be better off getting another dish 300 and a sat 119 lnb or just go ahead and get a dish 500/1000 or maybe a super dish?
