I dont notice any difference in the FM quality with the sharkfin.
I am comparing with my other car/same places and stations. Tons of more static on fm. It could be in general radio issue since I don't remember how much better it was on stock antenna. I don't listen fm much anyway.

for those of you who have installed the shark fin antenna....WHY??
I installed one because even with vehicle lowered tobpark mode and garage at max height the foot long antennae was hitting the garage backing out or in making a very annoying sound. Plus it flat out looks much better.
