How do I improve the bad radio signal in my 2007 Jaguar XK?

I have a 2007 Jaguar XK convertible. The radio reception is very poor and appears to be because of a bad aerial. The rest of the sound system is fine. I wondered where the aerial is and whether it can be replaced/repaired.
That was a common complaint with the XK convertible (Jeremy Clarkson complained about it) and it was fixed on later models. A Jaguar specialist will know what to do.
