Upgrade your factory antenna with this stylish yet functional (1.5 - inch) black powder coated Super Shorty billet aluminum antenna. Installation is very simple. This is a PLUG-N-PLAY antenna, which means it screws onto your existing antenna mount (a direct bolt-on part, no wiring involved) and takes a minute to do. This antenna replaces your stock AM/FM radio antenna and does not affect On-Star, Bluetooth, GPS Navigation, or Sirius XM radio as those Satellite services use a separate antenna in your vehicle. 4 out of 5 reception with most people noticing no difference at all. As a general rule, strong stations will be fine and weak stations will be reduced. One of the most inexpensive modifications you can do to your vehicle yourself and looks much better than the long stock antenna.
