Antenna Control Module: Description and Operation

The antenna module is an electronic circuit component designed to capture and enhance RF (Radio Frequency) signals in both the AM and FM broadcast bands. The antenna module is mounted to the right C-pillar (sedan) or rear liftgate (wagon). The module is grounded through the mounting bracket and fastener. The module has a two wire electrical connector that connects to the integral radio antenna and EBL grid, located on the rear window. There is also an electrical connector for battery voltage and a coax cable connector.

The antenna module receives both AM and FM radio signals supplied by the rear window integral radio antenna and selectively amplifies them. The amplified signal is then sent through the body length coax cable to the radio input.
