Default Aerial Diplex Plate


Not sure if I'm using the right terminology here so please bear with me!

I live in a retirement development with 24 properties and a communal
aerial. The aerial is wired to all the properties and carries Freeview,
DAB and what looks like an old FM band3 (?) aerial. It has masthead amps
and a distribution box and the cables run through our lofts to provide 4
outlets in each property.

DAB is a recent addition and I have a diplex outlet in the bedroom:

DETA BEY 11 (may be BCY 11, very small print).

It has two F Type sockets and a built in metal box containing the gubbins
to split the signal.

I would like another plate exactly like it in the lounge but I can't find
that model. I was given a plate this morning but it has co-ax sockets for
TV and DAB and I really would like F Type sockets.

Can anybody recommend a suitable plate please? Even a good place to search
would be useful, I have tried Farnell but no joy.

Many thanks.

How old is the property? On older properties, part of the distribution
equipment is within the sockets, so the socket would definitely be
outside the demise. Even with a newer property, you should carefully
check whether the socket is yours to replace.

In the old system, the sockets are daisy chained. Most of the signal
goes on to the next socket (or into a termination resistor), and only a
small part comes out of your socket. If you replace these you end up
with a very strong signal and your TV interfering with other people's.
In more modern systems, all this happens in the core of the building,
and only the final, tapped, signal is fed to your socket.

You could always use F adaptors, plugged into the Belling Lee sockets.

Band 3 is DAB. The older, FM system is band 2. (UHF TV is and 4 and 5.)

Mobile phones keep nibbling away at band 5

The current DETA catalogues are at
http://www.detaelectrical.co.uk/downloads. If you are very lucky, it
is still a current product.

It looks to me that they specialise in style, rather than engineering,
and probably aim at large builders, rather than consumers.

I'd suspect that anything with F connectors, other than for satellite,
is aimed at the US market.

Is it a double width wallplate, or single width? In the location where
you want to put the new one is there an existing double width wallplate,
or single width?

You don't mention satellite.

Is it something like this?:

It's unlikely to be a padded outlet system if the outlets are diplexed.
I don't think there's a product that does it.

And in the time it took to send that post they've sent me an email and
asked for my postcode so they can identify a supplier!!!

Service like that costs......

Yes, except it has 2 x F Type sockets like this:

But the one at Amazon doesn't have the decombiner/duplexer.
