I got this one at Autozone for $20...https://www.autozone.com/electrical-...0898_1468392_0

It's 17" or so. (If I remember correctly, optimal length is 31".)

Could you post a picture of your setup? The one from Autozone doesn't seat all the way against the fender mount but it's OK if you don't look close. I live just on the edge of two larger cities so we are experienced with FM amps and antennas. The longer length helps bring in the stations.

I'm gonna try the one you got from EBay and thanks for the post.
