No, DTT is digital *television*. If you want true digital radio that's
Digital Audio Broadcasting (DAB) and you can use an external aerial for
that as well, in fact your existing FM aerial might do.

I'm in a pretty high DAB field strength area but using my decent FM aerial
gave worse results than a bit of wire out the back of the tuner. DAB
doesn't take kindly to poor signal levels - you get a 'boiling mud' effect.
Of course it could be that a simple FM aerial of the halo type etc is so
poor in rejecting unwanted RF that it does work after a fashion on Band
III and Band II.

You usually don't need a highly directional aerial for DAB as multipath
doesn't worry it in the same way as FM, so a simple dipole is often
sufficient. Or if you have easy access to a suitable high fixing point a
'Slim Jim' made out of plastic water pipe and a few scraps of wire is a
good DIY method. I've got a roof terrace and mounted one of these on the
top of the access door frame and it works very well.
