A circuit arrangement (1) is described for compensating an attenuation (Ko, Ka, Ka1, Ka2) occurring in an antenna signal connection (2) between a mobile terminal (3) and an antenna (4) with at least one antenna signal amplifier (5a, 5b) in the antenna signal connection (2) and with a control unit (8) for setting an amplification factor (V) by which the antenna signal routed through an allocated antenna signal amplifier (5a, 5b) is amplified or attenuated. The circuit arrangement (1) has a detection unit (7) for detecting an antenna signal power (P) of the antenna signal in the signal path of the antenna signal connection (2). The control unit (8) is configured to adapt the amplification factor (V) at a rate of change slower than the control rate of an antenna signal power control loop between a coupled mobile terminal (3) and a base station (4) of a mobile network with which the mobile terminal (3) has a communication connection, to regulate the transmit power of the mobile terminal (3) at which an antenna signal is emitted by the mobile terminal (3) if the detected antenna signal power (P) lies in a range of a predefined lower limit value (PG1) for the detected antenna signal power and a predefined upper limit value (PG2) for the detected antenna signal power (P).
