Q: How do you remove the antenna mast on Chevrolet Blazer,S10,GMC Jimmy and Sonoma?
A: Use a small open-end wrench to unscrew the antenna mast. Then, you can unplug the antenna cable, and remove the cap nut as well as the adapter and the gasket. Loosen the screws that connect the antenna to the fender. Installation is the reverse of removal.
