Will a sl3-s LNB work with a SD receiver model D12? I know I can't get HD with this, but can I get SD? Also, do I need a power inserter for this LNB to work? I am using the 22" x 32" SlimLine dish. The LNB has a single output. complete model # is SL3SPIG-wnc. I think it is a SWM also ? ? Any advise is appreciated. Thank you.
