Antenna system 1, black
- Separate AM antenna loop at top of rear window.
- FM1 antenna on same connection as the heating element.
A filter in the antenna amplifier prevents the antenna signal from going to the heating element's power supply. An antenna filter on the ground side of the heating element prevents the antenna signal from going to ground.
- The heated rear window is connected to the antenna amplifier and antenna filter. A capacitor prevents the voltage from reaching the antenna amplifier. The rear window heating is grounded via the antenna filter.
The amplified signal is fed via a coaxial cable to the radio.
