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.
