Radio receiver system for motor vehicle, has HIFI amplifier supplied with direct current voltage, where voltage is applied from radio receiver to inner conductor of coaxial line

摘要

The system has a diversity module which is connected to multiple antennas so that a high frequency signal is supplied to the module. The module is connected with a radio receiver over a coaxial line. The module has a switching device for switching between different high frequency signals. A High fidelity (HIFI) amplifier (H) is supplied with a direct current voltage, where the voltage is applied from the radio receiver to the inner conductor of a coaxial line.
