    You do not need two signal wires to an FBC matrix. Use one wire to the matrix and use the "connected" option.

    „ Are you saying that the tuner really needs a direct unicable feed prior to splitting? If so it sort of destroys the concept of unicable doesn't it?“
    No - it doesn,t, but the splitters and their impedance does matter.
    My 27.5W LNB runs to a 2 way splitter - 1 path is to my lounge receiver (about 20 metres away), the other path goes to a 4 way splitter(about 12 metres away) - the output from the 4 way is significantly down (relative to the lounge receiver) and causes occasional loss of signal ( this is a new setup so I need to look at this setup and see if I can improve it!).

    Abu et al,

    Have done as suggested but as soon as I put the split line back onto the UHD UE 4K it fails.

    Then I noticed that although tuner A and B had no signal, C and D did! Still would not tune properly. So the new splitter arrived this afternoon and I changed them over. SCR 1 came back but kept dropping off then coning back. So I removed tuner D and gave scr 4 from tuner D to tuner A and the three remaining scr are working fine.

    I now suspect the splitter is fine but the LNB is the problem. The 24 way s due to arrive tonight so will try to fit it tiomorrow and see if that cures the problem. Seem to remember I bought a tuner tester in the dim past so will rifle through my stores to see if I can find it.

    If you are connecting to one LNB why do you need a splitter?

    Not sure that conclusion is right either as the cable when connected direct to the receiver worked properly so perhaps even these new splitters are not good enough quality? How can I tell?
    Are there any tests I can run on them to check them out?

    Huevos, in earlier posts I explained that I am wiring a new house using unicable. Plus I have several items that need attaching to the unicable circuit.

    How many cables have you got connected to this receiver?

    Hi all,

    It seems it was the splitter causing the problems. It is an intermittent fault but I have watched it (using the signal monitor) runing at 12 dB happily then suddenly dropping to zero for anything from 1 to 30 seconds.

    Have changed the splitter and retuned the Receiver and (uising one of the bands) the separate smart TV. The new LNB has been delayed but hopefully I will have eight bands on the Gigablue, four on the VBox and one on the smart TV before the end of the weekend.
