I am in need of some assistance. I am upgrading my directv to swm. I have the following receivers 1-HR24, 1-HR22 and 2 H21. I have the following parts. A new swm lnb, a power inverter, a 1x4 switch. What else do I need to connect all my receivers so it would work for whole home? And can someone possibly diagram it for me. I also have a DIRECTV DECA BROADBAND ADAPTER - DECABB1MR0-01. Rush assistance please. Thank you in advance
