Retrofit a better DAB antenna?

I've had my 59 plate D4 for almost 6 years and had resigned to the fact that the DAB signal was not good. 60% of that decision was put down to living in Northumberland.

Well I now have another new vehicle and the DAB signal is great. So does anyone know if it will be worth trying to find and fit a better antenna, or is the signal as much to do with processors or other hardware as it is a decent antenna?

I've ordered a new 3rd brake light lens, and I'm waiting to catch a windscreen fitter in the area to coax with some cash to fit it. But while I'm up there I thought I'd have a poke around the roof fin too see what's involved.

Someone on the RRS forum put a 2015 shark fin onto a 2011 with good results.

Thanks, I'll look into fixing hole compatibility first, then it might be possible.

I've found the DAB reception to be reasonably good - certainly much better than the only other car I've had with built-in DAB (a BMW).

IME in rural areas DAB coverage isn't generally as good as FM ...

Over 600 new DAB transmitters have been installed across the UK over that last few years, mainly to improve reception in the more populated areas where the signal wasn't so good. A good number of these were BBC DAB with all but local BBC radio stations on them.
There will still be some dead-spots even within the good signal areas though. FM will work there because the longer wavelength is more able to follow curvature of the terrain than the frequencies used for DAB.

Even older car DAB systems should now be able to cope better with the much improved coverage.

Some rural areas however will still not be as good - only about 85% of UK population areas are now covered effectively.

A good antenna though is the key - the digital signal is far more complex than FM and is subject to reflections off buildings compounded by movement. Newer radios should be more tolerant but a good antenna will always improve things.
It isn't helped because pretty much all antennas are amplified because they use an antenna length much less than 1/4 wavelength.
