Abstract: A circuit arrangement (1) for compensating for a damping occurring in an antenna line between a mobile radio terminal (2) and an antenna (3), comprising a plurality of partial branches (T1, T2, T3) in each case for assigned transmission services for specific frequency bands, is described.

Abstract: 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).
