AntennaX The Shorty (5-inch) Antenna for Pontiac Firebird fits 1982 thru 1993 Pontiac Firebird Replace your ugly factory (31 inch) metal shaft antenna with this stylish yet functional LOW PROFILE (5 inch) black powdercoated billet aluminum antenna PLUG-N-PLAY installation, which means it screws onto your existing antenna mount (a direct bolt-on part, no wiring involved) and takes a minute to do 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 Does not affect On-Star, Bluetooth, GPS Navigation, or Sirius XM radio as those Satellite services use a separate antenna in your vehicle
