I don't recognise it, it might even be optical. There's a logo just about visible on it (TE I think) so the TE website should be checked. What equipment did it come from, and what are its dimensions? Also, what's the distance between each of the positions on the connector? With that info it will be easier to identify.
I'm impressed that shabaz could make out the logo and happy that you found a match.
I'd have guessed that a major car manufacturer would use a lot of custom connectors and ensure that you had to pay up to get the official replacement - probably the whole antenna. Great to see that wasn't the case.
