May I try here? I see subsequently from Google that I can completely
hide one of these behind the dash (apart from the windscreen aerial).

I have a V expensive Blaupunkt in the old car. DAB plus all the others.
Which came with a windscreen mount DAB aerial. Totally useless. After
taking advice I bought an active DAB roof aerial (which also does the
others) and round London and the SE, DAB reception on that is way superior
to FM. FM reception on this is I'd describe as normal - some fading etc
between high buildings, etc. DAB is generally rock solid. But was awful
with the supplied aerial.

DAB aerials are powered either through an additional 12v connection or
through the aerial lead from the head unit. If the latter then make sure
the head unit is configured to supply power on the aerial lead.
