I originally posted a similar thread over in the Connected home section and realized it should have been here - so my apologies for cross posting. I have been reading a lot the past few days so I think I am on the right track and think I have a good plan for when the installer arrives - but can some of you "check my math" ? I want the install to go as smooth as possible and I want to clean up my mess of wires at the same time. I have 3 hr21's and 1 r16. I have a slimline dish with the 3 horn lnb with 4 wires coming out of the dish into a WB68 with 8 coax runs (2 to each receiver). I am on the "unsupported" ethernet MRV. When its all said and done, I will have the HR34 and three HR21's. The R16 is getting retired with one of the HR21's being relocated to its place. I am also switching to DECA for the MRV. My assumptions are (based on a whole lot of reading) that I will have 11 tuners when its all said and done and will need a 16 port SWM multiswitch, the DECA CCK, a power inserter, and at some splitters. Everything is centrally located in the basement where there is a 2'x3' space on the wall that all of the current wiring comes to along with the wb68 multiswitch being located there. At that location I have power and ethernet available. My plan is to place the WDECA (CCK), the power inserter, the SWM multiwitch, and the splitters at that central location and mount them all to the wall nice and neat. Questions: I believe that setup should work ok - any reasons why not? Will I still use all 4 lines from the outside - I think the answer is yes and the 4 lines will go into the swm16 multiswitch and my assumption is the dish and lnb will not need to be changed? I believe this to be true as well - the wireless deca/cck can be used wired instead of wireless? I also assume that the BBC's that are connected to each hr21 tuner will go away and I will need to add a DECA module at each hr21 location. Correct? Splitters - Since I have 4 physical receivers and 11 tuners, I will need splitters. I want them to be located at the central distribution point. Does each splitter need a power infusion? Doesn't appear to. So in theory I can get two of the 2 way broadband (with the green label) splitters and and then connect the four rg6 lines that run to each receiver. Any advice or math checking would be appreciated!
