It's pretty short overall, and I still have plenty of sensitivity. Newer cars have active antennas. I don't think mine is, but I'm not sure. It's basically the same setup as any other antenna, just the whip is shorter, and helically wound, I suppose for tuning purposes. I guess it's about 15 or so inches long. I'd have to measure it. Of course, it also functions for FM too. |
