Lousy radio reception on my D3 - is this a fix?

[Aussie Jeepster]

I don't think I am alone with the crappy radio reception on my D3.
But I'm wondering if I took the aerial connector off the top of the back driver window, and made an adapter to hook up a "normal" radio aerial, if it would make a difference?
The plug sort of looks like one of those 9 volt battery connectors, so I guess one side would be + and the other -.
Before I take the plug off the window, does anyone have any bright ideas if this is worth pursuing?

It does beg the question - why do you have poor reception - certainly mine is pretty good and matches my other cars with "normal" aerials - so is there an actual issue with your current system/ radio.

Unless you are going to add a big signal booster or a highly specialised aerial rather than a "normal" aerial I don't think there will be much to be gained.
