There are printed DAB+ aerials that just stick to the windscreen, these are really only for urban areas as they are very comprimised by their design.
For DAB+ signal, I have a purpose made 3db gain fiberglass whip antenna on a spring base swivel mount fitted to my MGF. It's mounted on the right hand side rear, opposite the AM/FM antenna.
This set up provides me with excellent DAB+ reception in fringe reception areas.
