Ok, it appears fromn your sig that you have 10 tuners. A SWiM LNB with one wire output only supports 8 tuners. They must provide a legacy SL3 or SL5 LNB (4 wire output) with a SWiM16 external switch. From the SWiM16, they must use both outputs as each output only supports 8 tuners. Each output would probably have an x4 green label splitter. For Internet connectivity, they will also be required to have one DECA adapter with PI connected to your router and the output connected to one of you feed cables either at the x4 splitters or with an additional x2 splitter somewhere in the system. Anything less than what I described above and your system will not work properly. Stick to your guns and make sure it happens the correct way.
