This vehicle-mounted radio system is provided with a plurality of antennas and a plurality of antenna cases (110, 130) that are for receiving the antennas and fewer than the number of the antennas. The vehicle-mounted radio system is provided with, as antenna cases: a roof top antenna case (110) disposed on the roof top of a vehicle; and an in-cabin antenna case (130) disposed in the interior of the vehicle. The roof top antenna case receives two or more kinds of antennas corresponding to one among an antenna (111) used for communication in which isotropic directivity is required in the horizontal surface and an antenna (112) required to receive a radio wave from above the vehicle. The in-cabin antenna case receives an antenna (133) for accessing a mobile communication line, which is a public communication line that a mobile wireless machine can access, to perform communication.

    本发明涉及车载无线系统。车载无线系统具备多个天线以及用于收容天线的多个天线壳体(110、130),该天线壳体的数量少于天线的数量。作为天线壳体,车载无线系统具备配置在车辆的车顶上的车顶上天线壳体(110)和配置在车辆的车室内的车室内天线壳体(130),在车顶上天线壳体中收容有两种以上的天线,上述两种以上的天线符合天线(111)以及天线(112)中的任意一种天线,该天线(111)用于水平面内的指向性要求各向同性的指向性的通信,该天线(112)需要接收来自车辆上方的电波,在车室内天线壳体中收容有天线(133),该天线(133)用于连接到移动通信线路来进行通信,该移动通信线路是便携无线设备能够连接的公共通信线路。
