I've been considering using a shark fin style amplified antenna on my Fox hatch. I'm thinking rear center of the roof just in front of the hatch or on the top of the hatch itself.

What do you guys think?

I've shaved the whip antenna already. My factory whip style would oscillate in certain wind or speed conditions and that flexed the paint over time just enough to cause a crack and rust. I currently have an amplified antenna embedded in the rear view mirror but suspect I'll get better reception with a shark fin style. I don't hate this newer style antenna.
