    • The enclosure of the receiver device is divided into an antenna vicinity enclosure 1 and a demodulation unit enclosure 2, which are connected by a single transmission cable. By disposing the antenna vicinity enclosure 1 in the vicinity of the antenna, the high frequency feeder cable drawn from the antenna to the antenna vicinity enclosure 1 can be shortened. The effect of pulse noise and high frequency noise picked up by the conventional feeder cable can therefore be reduced. Furthermore, the length of the feeder cables in a quantity corresponding to the number of antennas is then reduced and the wiring space for the feeder cable can be reduced. The demodulation unit enclosure 2 is disposed spaced apart from the antenna, and the wiring space for the transmission cable can be greatly reduced in comparison with a case where a plurality of feeder cables are wired in the wiring space.
    • 接收装置的外壳分为天线附近的外壳1和解调单元外壳2,它们通过单个传输电缆连接。 通过将天线附近机壳1配置在天线附近,能够缩短从天线向天线附近机壳1拉出的高频馈电电缆。 因此,可以减少传统馈线电缆拾取的脉冲噪声和高频噪声的影响。 此外,对应于天线数量的馈电电缆的长度被减小,并且可以减少馈线电缆的布线空间。 解调单元外壳2与天线间隔开设置,与布线空间中多个馈电电缆布线的情况相比,传输电缆的布线空间可大大降低。
