2003 Chevrolet TrailBlazer 4.2 S, 4WDSECTION Notes
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The antenna system receives broadcast AM or FM stereo signals from free space and sends the signals to the radio receiver for processing via a coaxial antenna cable. Good antenna grounding is important for good radio reception.

The antenna base and mast should be installed to the torque specifications provided in the Cellular Communications/Digital Radio Antenna ReplacementΒ  procedures.

The antenna mast is a single 1/4 wave design located at the right front fender.
