Antenna Systems
Since the standard locations for antennas on the roof or in the fixed
rear window are not available on the E93 Convertible, the various
antenna systems are distributed and integrated in the vehicle.
Antennas are required for the following systems:
• Radio
• Digital receivers
• Navigation
• Telephone and telematics
• Remote control
With the exception of the SDARS antenna, the E93 Convertible has
no visible antennas. The Convertible does not even have the
standard rod antenna, a feature contributing to the harmonious
appearance of the exterior.
AM/FM Antennas
Four FM antennas (FM1-FM4) and one AM antenna that are
switched via an FM antenna diversity function are used for radio
reception in the E93 Convertible.
Different antennas are used when the hardtop is closed or lowered.
When closed, the AM, FM1and FM3 antennas in the rear window
are used as in a Coupe. The antenna amplifier and the rejector
circuit for the rear window defogger are located on the left C-pillar.
There is only a rejector circuit on the right-hand C-pillar.
The E93 Convertible has many information and communication
antennas all of which, except for one, are concealed. Only the
SDARS antenna is located on the rear lid as this requires a direct
reception path to the satellites.
The antenna systems are divided into radio, digital receiver, tele-
phone, navigation and r
emot
e control.
