Has to be a reason for the fin...I had a 2012 and it was fairly flat but I know the sat and gps would go offline even under a bridge, a smaller bridge. This setup seems to get the better sat reception perhaps due to the side to side bounce? I wouldn't grind it without determining exactly how it works inside.
