New FM/DAB/UHF Installation
 
I'm putting together a system for distributing FM, DAB and UHF around
the house from the loft. I'm planning to use a combiner and amp to bring
together all the inputs (Proception proAMP310X) and drop a single cable
to each room.

So, 2 questions:

1. At the moment, there is only one room in the house needing both TV
and FM/DAB, so I'll use a wall plate. For the other rooms that just need
FM or UHF can I just connect the cable direct into radio or TV, or DO I
need a splitter of some form?

2. In the room needing UHF and FM/DAB, I have just bought a AV AMP that
does both FM and DAB, but on separate inputs (not very convenient, but
there you go). Is it going to be OK to tee off the output of FM side of
the plate using something like a labgear 2 way splitter? I'm thinking it
should be neater than trying to make a Y cable up. The only downside I
can think of is the insertion loss.

Any suggestions gratefully received.

Cheers - Kev

Just connect straight in, or use a single outlet (as illustrated in the
instructions for the '310X). Provided signal levels on the system are
sensible you shouldn't have any problems.

The VHF (radio) side of the outlet plate needs to pass both FM and DAB
frequencies, i.e. should cover 88 to 230 MHz. Not all do, so be
careful. An FM-only one is likely to attenuate the DAB signals
excessively to the radio port. Otherwise a basic 2-way splitter used as
you suggest will usually be fine. 3 or 4 dB insertion loss at VHF is
unlikely to be much of a problem unless the off-air signals are
particularly weak, in which case you'd really need more aerial gain.

A Global WPTV/FM/UK is good for the wall plate as it is designed to
pass FM and DAB on the one side and TV on the other.

Maxview make a plug in diplexer to seperate FM and DAB. It is metal
and therefore fully screened and rather like a "Y" splitter except
that the input is on the front rather than on the end.
