Circuit/System Description

The multi-band antenna is located on the roof of the vehicle. The radio provides battery voltage to the antenna amplifier in the antenna base enabled when the radio is turned on. When the antenna amplifier is enabled, both AM and FM signals are amplified. The amplified signals are sent to the radio via a separate signal circuit.
