如图1所示，主机模块与从机模块之间通过OOK消息链路进行通信，从机模块可通过OOK消息链路与主机模块进行通信并实现自身固件升级。具体地，OOK消息链路包括第一SMA接口、第二SMA接口，及连接第 一SMA接口和第二SMA接口的同轴线缆，同轴线缆可用于传递OOK信号和DC信号，其中，第一SMA接口设于主机模块中，且第一SMA接口与主控制器相连，第二SMA接口设于从机模块中，且第二SMA接口通过第二OOK调制解调器与从控制器相连。

本实施例中，主机模块和从机模块均包括用于提供电源的电源模块、用于EMC抑制的EMC抑制模块和用于防雷击的雷击防护模块。
进一步地，主机模块还包括电机驱动模块、浪涌电流抑制模块，其中，电机驱动模块用于控制天线内部的电机，进行天线相位调整；浪涌电流抑制模块用于对上电瞬间产生的浪涌电流进行抑制。从机模块还包括阻抗匹配模块，其可实现天线和基站之间的高可靠性通信。
