Speaking of antenna signal strength....

There's no chance that I could plug this into my car's FM antenna and expect it to work and get better reception, is there?

I went to a lot of trouble to get the thing's little disc antenna mounted in my dash under the windshield, but it was tricky and I'm getting slightly lower reception than when I had it on top of the dash.

I noticed it was a shielded coaxial cable connecting the disc antenna to the PCB, and I didn't want to de-solder it to extend the cable length.
