[QUOTE="PaulR, post: 114607, member: 176256"] Without a part number or link to the Maplin site I can only do bit of guessing so here goes. Some wall plates need separate leads connecting to them for each of the outlets - it sounds like yours isn't this type. Which leaves the type with a demultiplexed output. This has one input but then uses tuned filters to separate the terrestrial TV frequencies from the higher satellite frequencies. Unfortunately it isn't easy to insert the terrestrial frequencies into a standard digibox minidish LNB. The wallplates are normally used in TV distribution systems where there is a commercial multiplexer for all the various frequencies. There's even a special 4 output LNB for this. I m not aware of any proper frequency combiner but it [I]may[/I] be possible to use a 2-way signal splitter in reverse provided it has a DC path through to one of the ports only. This is the one you should connect to the minidish. If this doesn't work (and it is a bit of bodge after all) then I'm stumped. PaulR [/QUOTE]
