I can't be alone with this problem. 

We have DAB radio built into out Dacia Duster, and also have DAB radios at home, and the signal for DAB radio is fairly weak on most of the channels. 

If we are out in the car depending on where we drive, the signal will drop out and the radio station will just cut out which is very annoying. 

 

Does this just depend on the location, we live in Cornwall. 

And can anything be done to improve DAB radio signal?

 

We didn't have this problem with FM radio.

Installing an amplified antenna in your car might help.

e.g. Amazon.co.uk User Recommendationref=sr_1_3

A number of ebay sellers sell a FM/AM signal boosters (suitable for DAB) that work over the 88-108MHz range for less than £10.  Bear in mind that they only offer around 12dB gain (4 x voltage signal gain).

To install one, you need to get to the back of your vehicle radio (to add it to the rf signal input) and connect a +12V power line to it, which can be difficult with modern vehicle dashes.

^^^ " . . . that work over the 88-108MHz range . . . "

DAB transmissions use a range of 194 to 230 MHz.  So, if you're looking for any kind of 'booster', that's the frequency range that it needs to work on.
