To remove the antenna take off the trim panel in the area of the given antenna that may mean pulling off the rear light cover. Then remove the antenna mounting bracket and then disconnect the wiring as well. If so provided, and if not already loosened, rotate the mounting nut at the body hole and withdraw the antenna from the hole. For installation, insert the antenna back in and fasten it with the mounting nut at the body hole. Reinstall the mounting bracket and join the wires before, at last, fixing the trim panel.
