I have this elliptical dish (24x18) and (2) dual output LNB's (one for 101 & one for 119). The current multiswitch has LNB (2) A & (2) B inputs, plus 2 outputs. Each LNB has (2) coaxial cables and all (4) connect to the current multiswitch. All the replacement multiswitches I see have single LNB inputs. I only have the one Hughes HD receiver, and I only plan to add one more receiver down the road. What is the BEST multiswitch I can buy?
