Patent ID: 8457700

Claim:
Global Positioning System (GPS) mast module comprising: at least one satellite antenna (GPS-ANT; GPS-ANT 1 , GPS-ANT 2 ), at least two connections, namely a base-station-side connection and a mobile-communication-antenna-side connection, a portion of a main high frequency (HF) path for transmitting HF transmission and/or receiving signals of a mobile communication system extends between the at least two connections, the at least one satellite antenna (GPS-ANT; GPS-ANT 1 , GPS-ANT 2 ) is coupled to at least one portion of the main HF path via a satellite receiving line, a low-noise satellite reception amplifier is provided in this satellite receiving line, the low-noise satellite reception amplifier has on the output side at least one frequency selector for suppressing one or more mobile communication frequencies of an antenna (ANT) which is or can be connected to the mobile-communication-side connection, the supply circuit for the main HF path is constructed in such a way that a) a loose connection of the output of the frequency selector to the main HF path is provided by a hybrid coupler, and b) the amplified satellite signal is supplied with a coupling attenuation of at least 10 dB by the hybrid coupler, the satellite reception amplifier having an attenuation at least 6 dB greater than the coupling attenuation of the hybrid coupler.
