Fig.7 Antenna Module
ANTENNA MODULE - EXPORT
The antenna module is an electromagnetic 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 rear roof rail under the headliner. The modules mounting brackets also double as the
ground circuit. The module has a two wire electrical connector that connects to the electric backlite integral radio antenna, located on the right rear
quarter glass, a connector for the radio coax cable and a connector for battery voltage.
The antenna module receives both AM and FM radio signals supplied by the side window integral radio antenna system and selectively amplifies them
while at the same time avoiding unusable or unwanted signals. The amplified signal is then sent through the body length coax cable to the radio input.
