Philex wallplate

[gumboe]

I recently bought a Philex 'screened twin coax outlet with sat outlet' wallplate from Maplin. My question is (as there are no instructions with the wallplate) how do I connect this up?

I've got a sky engineer installed minidish with a single LNB, I plan to put up a terrestial tv and a separate FM aerial up soon. I live in a poor reception area so I'll probably need something the size of a kids climbing frame on the roof.

As far as I know - I will need 3 coax cables coming down from the roof to the area behind the tv. This is why I've got myself the Philex wallplate, because I think this is what I need so that I've got easy access connections on the wall for FM / TV / SAT.

How do I cable this wallplate up? Inside the wallplate there only appears to be 2 places I can screw down some coax and these aren't labelled. Shouldn't there be 3 coax holes on the back of the wallplate.

Is there a better way to be doing all this?

Thanks for any help you can give.

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 may 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.

Thanks for the reply Paul, btw the maplin product code for the wallplate I bought is L72AN website is maplin.co.uk

I think I'd prefer to use a wallplate that takes 3 leads 1 for each outlet, do you know of any brands or models I could look out for.

Cheers

maplin website says this is for just one cable, ie for multiswitch output feeds (see my multiswitch guide in members' FAQs), If so, you'd have to combine tv and fm and sat using a 2Ghz 3 way splitter (in reverse), cheaper to get correct wallplate instead!

But if 2 inputs, as you say, then one is tv/fm (so combine those), other is sat alone, should be obvious which is which by following wiring.

Wickes tv/sat wallplates are fine, £3 each!

Just a standard triplexed outlet plate. You can deal with this by using an external VHF/UHF Diplexer and then an external SAT/UHF and VHF diplexer, running in to the plate with one cable.

The other way is to use one of the modular units, several companies do them, you get a socket frame and then can insert the modules required, but only two per single socket.

PS. On the plate you are using, only one side of the connection works, the other is redundant.
