Where to get Antenna Adapter?

[doogee]

Does anyone have any idea where I can find an antenna adapter for my e36?

I got one off ebay a while ago and haven't been able to get decent reception at all and figured it was the actually antenna being shotty.

So I pulled the deck out and fiddled with it and if I wiggle the antenna plug around I can get it to be crystal clear.

So I just need a new adapter that works.

Thanks
