I have been looking at this issue recently as I want to fit a radio. I have decided DAB is the way to go if I am going to the trouble. There are DAB aerials available they seem to have fairly large bases though and are about 350cm long. I had wondered about putting it under the spare wheel and poking up through the gap alongside the high level brake light. Would not be too obtrusive, but do the experts think it would be too shielded down there?
