Thanks for the reply Al.

I wouldn't have expected the signal to die completely when the antenna
is disconnected, I would have expected to still be able to hear
something. However, I tested my scanner by tuning and holding a weather
station, and then disconnecting the antenna. The signal went dead
completely, turning the Squelch down caused static, but I expected
that. So based on that, the antenna connector seems to not be the
problem. I'm going to play around with it somemore and see if I can
deduce the problem anymore.

Thanks again.
