Antenna
Antenna and diversity
The antenna used for the radio,
telephone and FZV remote entry
system is integrated with the rear
window defogger in the Sedan and
Coupe models.
Convertible and Sport Wagon models
feature a diversity antenna system to
provide the strongest possible radio
station signal to the sound system.
In this system there are two (or more)
antennas. Both the main and the
auxiliary antenna(s) receive radio
signals and both signals are amplified
in separate amplifiers. The signals are
then transmitted to the diversity
switching module, which locks onto the
strongest signal and sends it to the
radio receiver.
Sport Wagon antenna system
The diversity antenna system on the
E46 Sport Wagon consists of the
following;
FM1 antenna in rear window (right
half)
FM2 antenna in rear window
(center)
FM3 antenna in left rear side
window
AM antenna in rear spoiler
FZV (keyless entry) antenna
combined with FM2 antenna
The FM1/FM2 antenna amplifier is
located beneath the rear spoiler. The
signal from this amplifier is transmitted
to the diversity module in the cargo
compartment behind the left trim panel.
1 - Suppression filter
2 - Antenna amplifier
3 - AM antenna
4 - Diversity module
The FM3 antenna has a separate
amplifier integrated into the diversity
module. The module will select the
clearest signal from the three antennas
and transmit that to the sound system.
The AM antenna is glued to the bottom
of the rear spoiler.
Convertible antenna system
The diversity antenna system on the
E46 Convertible consists of the
following:
Main antenna mast on left rear
fender
Auxiliary antenna in convertible

Main antenna amplifier, mounted
directly below the antenna mast
Auxiliary antenna amplifier,
