DAB radio and External Aerial

[R11ysf]

Can you have one without the other? I've just bought a Mk2 'S' and it doesn't have an external aerial. I'm not too concerned with this as I don't think they look great, but does this also mean I will not have DAB?

I have a DAB radio without an external ariel, There seems to be a wire antenna running beneath the gearbox tunnel cover.
