DAB-FM antenna splitter
 

Apologies to some who may have seen this query elsewhere.


I have recently acquired a 'shoe-box' Yamaha unit with DAB and FM
and each has its own antenna connection (F and B-L respectively.)
I have UHF/FM/DAB antennas all combined (on individual inputs) by
a Televes loft amp/distribution, so TV and radio - required at
the same place - will come down one cable.

I'm sure I've seen somewhere recently a simple cable adapter that
has a B-L plug on one end and two short cables after a split one
with B-L and the other with F-type to feed the two inputs to the
radio, but can I find it?

I don't want to use an active solution if I can avoid it but I
also need to keep losses down. There are plenty of FM-UHF
splitters around but the frequency range of the outputs is never
specified.

Anybody seen what I am after?

FM - UHF spitters are generally "cross-overs" sending the 88-108MHz FM band
to one output and the 470-860MHz UHF TV band to the other. Depending on the
design Band 3 where DAB resides might be found in one output or the other,
or both or neither; so these are best avoided.

Simple wideband splitters are widely available and are your best solution.
There are resistive types, with a loss of 6dB to each output, and slightly
more expensive inductive types with a loss of about 3.5dB to each output.
Any dealer in aerials and aerial accesories will stock them.

Commonly they consist of a small metal box with 3 co-axial connectors of the
same type, such as:

You will need an adaptor cables to convert from whichever connector type
your splitter uses to fit the inputs of your receiver.
