not sure where I should have posted this, anyway I have a 98 Corvette
and it uses diversity reception. There is one antenna embedded in the
front glass, and another in the rear glass. The control/switching box
is above my head.

My FM reception really really sux on my coup, even with an aftermarket
radio. The reception in my 97 Maxima (which has diversity reception- 1
power mast style antenna, and one in the rear glass style) has the
best reception for a car radio I've ever seen. Anyway, it does not
help my front antenna was rubbed off, probably cause there used to be
a tint strip there and that was taken off. I repaired that the best I
could with circuit board repair conductive paint. However, the
reception still leaves to be desired.
I am thinking about putting in a power antenna on the rear fender from
a 03 Corvette convert. I cannot get ANY AM stations whatesover and
most FM is rather fuzzy. now that I'm on the highway alot, I need to
depend on the AM and FM to check traffic (and I cant stand it when I
know that something is wrong with my car).

Or, is there a way to check that my current diversity reception is
functional right now? Thanks
