Damn, that looks like the exact antenna I got off of ebay, except I paid twice as much. Oh well...

In regards to the CB antenna (I assume you are referring to the magnetic mount of similar size?), I had one when I first got my Cobra 75, but tossed it when I couldn't get squat for range & reception. So, I did something similar to what most people have done...EZ-over mount w/ a Firestik, mounted very discreetly along the rack rail. Looks very nice and doesn't scream redneck like a lot of other antennas do.
