Antenna System
The antenna system for the AM/FM tuner module (AFM) consists partly of an AM antenna and partly of a dual antenna system (Diversity reception) for FM (FMmain and FMsub).
The dual antenna system is used to reduce Multipath interference.
On 4-door vehicles a combined AM/FM (main and sub) and TMC-antenna is used. The antenna is integrated in the rear windshield.
On 5-door vehicles there are two antennae. A combined AM/FMmain antenna, which is integrated in the right-hand side rear window. An FMsub antenna, which is a combined FMsub/TMC antenna and is integrated in the rear windshield.
The signals from the antennae are amplified or adjusted by an antenna amplifier.
The signals from the FMsub/TMC antenna are transmitted via the antenna amplifier to the traffic message channel module (TMC). The traffic message channel module (TMC) in turn transmits the FMsub signals to the AM/FM tuner module (AFM).
