Antenna: Description and Operation

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. The antenna cable is a coax cable, which connects the radio to the antenna. The antenna ground should not exceed 50 m ohms when measuring between the antenna connector shield and negative battery terminal. The antenna mast should be installed to the torque specification specified in the Removal and Installation so that it will not become loose and fall off In the United States, the AM broadcast is 530-1710 KHz in 10 KHz steps while the FM broadcast is 87.9-107.9 MHz in 200 KHz steps.

The sedan and wagon have different antennas. The sedan uses a mast antenna mounted on the left rear side of the vehicle. The wagon has a rear roof mounted antenna.

The sedan fixed mast antenna has a single 1/4 wave monopole receiving element which protrudes from the vehicle. The antenna is mounted on the left rear quarter panel area sheet metal via a bracket attached to the wheelhouse inner. The fixed mast antenna directly receives RF signals and feeds the signal directly to the radio head for processing.

The wagon active roof antenna system uses a single short monopole receiving element which is mounted to the rear roof sheet metal of the vehicle. The passive roof antenna directly receives RF signals, processes these signals, and sends them to the radio receiver.
