Post by Natedog on Feb 12^th, 2012, 4:18pm

i've just bought a 2nd dab radio. both of them need an external aerial. what do i need to split the signal from the aerial i've got to feed both units?

FM and DAB are quite resiliant - You may find simply splitting the cable with a standard Y splitter is enough if your aerial is already recieving a good strong signal. (50% to each tuner). If your tuners have seperate FM and DAB inputs you would essentially only get 25% to each input, but again, if your aerial is positioned well, this would more than likely be ok. The best thing to do is to try it!

If you find you need to boost the signal, most TV dist-amps have an FM input, and than these will boost and distribute the FM signal too, either on their own or with the UHF TV signal too.

As Lectrician said. Many TV distribution amps will mix the signal from a TV and a DAB/FM aerial and send it to all the existing TV aerial points.

If you already have a TV distribution amp and it doesn't have an input for a DAB/FM aerial it might be possible to use a diplexer to allow both aerials to be connected to the one input. However you might need to check the spec for the distribution amplifier.

Sometimes a TV aerial will also work as a DAB aerial if you have a spare one lying around.
