Mobile radio device for a vehicle, in particular rail vehicle, having at least one first and one second transceiver (100, 200), which each have a transmit module and a receive module, having one or more transmit antennas (120, 220, 320) for transmitting and having one or more receive antennas for receiving, wherein at least one receive antenna used jointly, which is referred to below as joint receive antenna (500, 501) and with which a receive signal is received, is connected both to the receive module of the first transceiver and also to the receive module of the second transceiver and wherein a first transmit antenna is connected exclusively to the transmit module of the first transceiver and a second transmit antenna, which is arranged at a distance from the first transmit antenna, is connected exclusively to the transmit module of the second transceiver, - in which the receive antenna or receive antennas, which are connected to the receive modules of the first and second transceiver (100, 200), are separated from the transmit modules of the first and second transceiver (100, 200), - in which the transmit antenna or transmit antennas (120, 220), which are connected to the transmit modules of the first and second transceiver (100, 200), are separated from the receive modules of the first and second transceiver (100, 200), - in which the joint receive antenna (500, 501) is joined via an antenna connecting line to a signal input of a signal preparation unit preparing the receive signal for a filtered and reinforced receive signal (Efv), said signal preparation unit being connected on the output side to the receive modules of the first and second transceiver (100, 200), - in which a signal output of the signal preparation unit is joined via an intermediate line to a signal input of a distributor unit distributing the filtered and reinforced receive signal (Efv) to the receive modules, said distributor unit being connected on the output side via a first assigned receive line which is separate or individual to the transceiver to the receive module of the first transceiver and via a second assigned receive line which is separate or individual to the transceiver to the receive module of the second transceiver and - in which the receive modules are embodied to evaluate the filtered and reinforced receive signal (Efv) in each case. - in which the receive antenna or receive antennas, which are connected to the receive modules of the first and second transceiver (100, 200), are separated from the transmit modules of the first and second transceiver (100, 200), - in which the transmit antenna or transmit antennas (120, 220), which are connected to the transmit modules of the first and second transceiver (100, 200), are separated from the receive modules of the first and second transceiver (100, 200), - in which the joint receive antenna (500, 501) is joined via an antenna connecting line to a signal input of a signal preparation unit preparing the receive signal for a filtered and reinforced receive signal (Efv), said signal preparation unit being connected on the output side to the receive modules of the first and second transceiver (100, 200), - in which a signal output of the signal preparation unit is joined via an intermediate line to a signal input of a distributor unit distributing the filtered and reinforced receive signal (Efv) to the receive modules, said distributor unit being connected on the output side via a first assigned receive line which is separate or individual to the transceiver to the receive module of the first transceiver and via a second assigned receive line which is separate or individual to the transceiver to the receive module of the second transceiver and - in which the receive modules are embodied to evaluate the filtered and reinforced receive signal (Efv) in each case.
