Diversity Antenna (If equipped)
The diversity antenna system may use both the back window antenna and an antenna internal to the antenna module. Any damage to the rear antenna requires replacing the glass. This system is designed to deliver the best radio signal reception possible. Two antennas are used to form a diversity system. The primary antenna is part of the rear window and looks similar to the defogger grid. This antenna receives both AM and FM signals. The secondary antenna is part of the antenna module.
The antenna reception signals are sorted out by the radio antenna module. The radio antenna module is enabled when the radio is turned on. Superimposed on the powered antenna coax is the strength of the signal being received by the antenna module. The antenna module switches between the antennas, monitoring the radio signal strength and combines the signals and phase aligns them to create one strong signal.
