How have they managed this, or is it as complex as just using the FM
aerial
and hoping for the best?

Probably just using the standard VHF FM antenna for the reception of DAB.
Lets say the FM antenna is a 1/4 wave at, say 100MHz, then it must be a 1/2
wave at 200MHz, but that is still a few MHz out for DAB. Close though. Of
course that doesn't take into account impedance!

On the other hand, the unit may have a built-in antenna tuning unit, which
would be as simple as a couple of inductors and capacitors, which would
switch in when the DAB service was selected. Not rocket science.
