Antenna system

An antenna system comprising:

• a transceiver and control unit operable to control the antenna system and to generate a RF transceiver signal;
• a compensator connected to the transceiver and control unit through a connecting line, the compensator being operable to compensate for signal losses occurring for the RF transceiver signal in the connecting line between the transceiver and control unit and the compensator;
• an antenna interface provided at the compensator operable to transmit an antenna output signal with a variable output power;
• and
• a bidirectional communication line operable to provide a bidirectional communication between the compensator and the transceiver and control unit,
• wherein the transceiver and control unit is operable to indicate to the compensator through the bidirectional communication line a desired value of the variable output power to be present at the antenna interface when the antenna output signal is output by the antenna interface, and
• wherein the compensator is operable to transmit a heartbeat message through the bidirectional communication line to the transceiver and control unit indicating whether the compensator is operating normally, the transceiver and control unit being operable to determine an operating status of the compensator based on the heartbeat message.
