Preliminary remark  

This description concerns mainly the audio, CTEL and navigation antenna system for vehicles fitted with 
COMAND or radio and navigation unit (MCS). 

General  

The different antennas are matched in terms of design to their specific reception and transmitting ranges. 

A distinction must be made between passive and active antennas: 

Passive antennas do not require a voltage supply, they can therefore not directly amplify the radio signal 
received. 

Active antennas are supplied with voltage. They feature an integrated amplifier. 

The voltage can be supplied over separate cables or over the coaxial cables over which the actual signals are 
transmitted simultaneously ( phantom feed ) . In this case, no separate leads are required for the power 
supply
 .

A further distinction in terms of the antennas is that certain antennas are used only for reception while others 
are used both for reception as well as for transmission . 

Function up to 31.08.01  

The CTEL and GPS roof antenna (A2/49 ) is supplied with direct voltage via the antenna cable ( phantom 
feed
 ). 

It is connected by a coaxial cable to the CTEL and GPS antenna splitter (A2/57) . These two components 
ensure reception and transmission of the GSM signals and reception of the GSP signals . 

Function as of 01.09.01  

The CTEL and GPS roof antenna (A2/49) has the antenna splitter and an antenna amplifier integrated, which 
eliminates the need for the CTEL and GPS antenna splitter (A2/57) . 

 The detailed descriptions of the individual systems and components are given in the reference documents 

listed below.
