works great
Ordered this replacement part after my OEM was damaged (Broke going thru car wash). Easy replacement and looks exactly the same. Good price and works great. I also purchased a short replacement antenna.

Fits 2024 Chevy Trailblazer
Very easy to uninstall broken one and replace with new one. Does not come with the actual antenna however the old antenna was salvageable. The base itself was broken. Saved myself hundreds of dollars. I’m a woman who didn’t really know what I was doing and it only took me 20 mins. And I can confirm it fits a 2024 Chevy trailblazer.

Great replacement
Mine was ripped off from a car wash.. so bought this to replace it for a 22 Chevy trailblazer RS. Install took some time and patience. No fault of the product itself, just builder design of vehicle. This has been installed for several months now and there has been no issues. Also seems to be built better than original. No water leaks that I have noticed. Paired with the new antenna I got, it has good reception.
