I think you get the option of changing the vehicle-specific antenna straight away. Personally, I was not a fan of the DAB antenna supplied with a 1-din radio.

When you buy an FM car radio, it doesn't come with an FM antenna either... ;-) My cheap Kennwood DAB radio came with an antenna and it works perfectly! But it may not be to everyone's taste to stick an antenna on the windscreen. Others might prefer to use the original antenna and convert the signal, others might want a shark-fin DAB antenna, etc.

The DAB antenna is included in the scope of delivery of this product.
