anyone fitted a proper aerial instead of shark fin.

hi the radio signal on my 13 plate insignia estate is crap has anyone tried changing from a shark fin to a proper aerial ?
i know the shark fin is for the nav so i would have to get an aerial that has am/fm/gps and dab to as i have an autodab thing lying around.
would it be possible
or am i better of drilling a hole and put a dab/fm aerial as well.. any ideas
cheers.

I think the dab aerial is in the rear window so the shark fin doesn’t affect this, I have issues with the dab signal on mine aswell

i dont have dab yet but the fm signal is terrible ,
