CTEL and GPS roof antenna (A2/49)

The CTEL and GPS roof antenna (A2/49) is a combination antenna for the telephone and GPS.

The integrated GPS antenna (A2/49a2) receives the GPS satellite signals. This antenna does not transmit
signals.

The integrated CTEL antenna (A2/49a1) receives and transmits GSM radio signals.

The CTEL and GPS radio signals are transmitted to an antenna socket used by both. For this reason only one
antenna cable is required.

The CTEL and GPS roof antenna (A2/49) is an active antenna. It is supplied with DC power via the antenna
cable (phantom feed). The electronic circuitry in the antenna must ensure that



the telephone transmitter signals are only transmitted to the CTEL antenna (A2/49a1) .



the signals received by both antennas are available at an antenna output.

The antenna is connected to the CTEL and GPS antenna splitter (A2/57) by a coaxial cable.
