Shark fin antenna for Honda jazz 2017

[Hicabod36]

Hi  I  am a newbie to the forum my I’d is Hicabod36

I have a problem with the shark fin antenna it got damaged when reversing out of my garage. The up and over door got blown down by a strong gust of wind and caught the antenna as I was reversing out.

Does anyone know where I can get a replacement antenna one that works with all frequencies including DAB radio.

I see them advertised on the web quite cheep but I am unsure of the quality.

please any advice would be appreciated 

I am going around with a plastic bag taped over the remains to keep the weather out

any advice would be most appreciated
