Review on 📻 7 Inch Short Antenna for Chevy Silverado GMC Sierra (2007-2021) - Designed to Fit OEM 22876545 22936386 15074562 - Featuring Copper Core - Ensures Enhanced AM/FM Reception with Premium Quality - M7 Thread by Bill Lacy

Easy installation. You may need a 10mm wrench to remove the existing antenna. Just hand-tighten the new one. So far it seems to be a good reception. It seems to take a little longer to fill up the HD Radio info, but not that long. Basically satisfied. *Update* This took about a year. I go to the car wash about once a week, so that's a beating. I really liked this antenna. Added a photo of the breaking point. It appears to be the same location as the other user. It looks like both were bought around the same time in January 2020.
