Circuit/System Description

WARNING: This page is about a different car, the 2018 Buick Regal TourX and 2018 Buick Regal. However, it is still accessible from the selected car via links, so may be relevant.

Quarter Window Antenna

The active antenna system uses an integral antenna applied as an applique to the rear quarter window. The antenna module receives FM2 signals from the rear quarter window. The radio antenna module is enabled when the radio is turned on. The radio provides battery voltage to the antenna module using the center conductor of the antenna coaxial cable. When a 12 V signal is seen by the module on the center conductor of the antenna coax, FM2 signals are amplified.

Rear Window Antenna

The active antenna system uses an integral antenna applied as an applique to the rear glass. The antenna module receives FM2 signals from the rear glass antenna. The radio antenna module is enabled when the radio is turned on. The radio provides battery voltage to the antenna module using the center conductor of the antenna coaxial cable. When a 12 V signal is seen by the module on the center conductor of the antenna coax, FM2 signals are amplified.
