FM Antenna Diversity
In the F01/F02, an FM antenna diversity is standard equipment.
The FM antenna diversity comprises:
• FM1, FM2 and FM3 antennas
• FM antenna amplifier with diversity module
The FM1 to FM3 antennas route their RF signal to the antenna amplifier in the antenna
diversity module.
The signal quality of the currently selected FM antenna (FM1 to FM3) is now evaluated in
the antenna diversity module.
The high-frequency signal from the active FM antenna at any particular time is fed by the
antenna amplifier and antenna diversity module via a coaxial cable to the tuner module in
the head unit.
The tuner module in the CIC is now informed of the station selected by the customer
using iDrive. As a result, the tuner module in the CIC selects the matching frequency.
This is done by setting a bandpass filter. The bandpass filter suppresses all frequencies
above and below the selected station frequencies.
