 A GSM cellular telephone can be connected by means of a coaxial cable to the non-designated 

connection.  

The CTEL and GPS antenna splitter (A2/57) consists of the following components: 

Active frequency splitter with GPS antenna amplifier  

Coaxial socket for the CTEL and GPS roof antenna (A2/49)  

Coaxial socket for a GSM CTEL  

Coaxial socket for a GPS receiver  

 The voltage for the CTEL and GPS antenna splitter (A2/57) is supplied via the coaxial cable from the 

GPS receiver ( phantom feed ). 

ANTENNA SPLITTER, FUNCTION - GF82.85-P-3107-04B 

Model 163 with code 353  

The CTEL and GPS antenna splitter (A2/57) has the following functions: 

Separating the signals received from the CTEL and GPS roof antenna (A2/49) : 

The GSM and GPS signals are received by the antenna splitter via an antenna lead and leave the CTEL 
and GPS antenna splitter (A2/57)
 via two separate coaxial cables. In addition the GPS signals are 
amplified. 

Decoupling the GPS receiver from the GSM telephone transmitter: 

It must be ensured that the telephone transmitter signals do not reach the GPS receiver. The CTEL and 
GPS antenna splitter (A2/57)
 allows them to pass only in the direction of the roof antenna.

The CTEL and GPS antenna splitter (A2/57) has the following functions:

Separating the receiving signals from the CTEL and GPS roof antenna (A2/49) : 

The GSM and the GPS signals are received along an antenna cable at the antenna splitter and leave the 
CTEL and GPS antenna splitter (A2/57) in two separate coaxial cables. The GPS signals are 
additionally amplified. 

Decoupling the GPS receiver from the transmitter of the GSM cellular telephone: 

The transmission signals of the cellular telephone must not reach the GPS receiver. They are passed 
through by the CTEL and GPS antenna splitter (A2/57) only in the direction of the roof antenna.
