A: To remove the antenna, the antenna mast simply unscrews from the base, it can be unscrewed by hand, but if necessary, use a pair of pliers to break it loose. Remove the rear quarter trim panels and the rear garnish molding at the rear of the headliner. Pull the rear of the headliner down for access to the antenna base. Unscrew the antenna base nut, disconnect the cable, and detach the antenna base from the roof. Installation is the reverse of removal.
