I've been loving my new Trailblazer.

However, there's one thing about the exterior that I just can't seem to "unsee", for lack of a better word. It's that silly little antenna sticking up off the roof. I think that for a 2021 car, it's a little bit out of place.

Thinking of replacing it myself with a 3rd-party shark fin... Anyone thinking of doing the same or have any advice?

Thanks in advance.

The problem I'm seeing is the base of the Trailblazer antenna is freakishly large for some reason. Finding a cover that fits has been a challenge. The one I used (Possbay) I had to modify so it probably isn't the last one I'll be using but for now it does the job.

What I would really like to know is there a stock antenna (fin style) off another vehicle that could be directly swapped with the one on the Trailblazer. That would seem to be the optimal solution.

There are definitely shark fins on other GM vehicles. Maybe one of them would be compatible?
