摘要： A low profile, vehicle mounted, in-motion tracking, satellite antenna includes a pair of antenna assemblies mounted in parallel on a rotatable platform. Each antenna assembly includes two subreflectors with a plastic matching element. The outputs of the two antenna assemblies are coupled with a single phase shifter. The combined outputs are retransmitted to a receiver inside the vehicle. The satellite antenna also includes a receiver for receiving channel selection data and/or for providing two-way communication with equipment inside the vehicle. The antennae, transmitter and receiver are self-powered by a storage device which is charged by a wind driven generator. A retractable radome lowers to a lower profile when the antenna is not in use.

摘要翻译：一种低调的车载运动跟踪卫星天线包括一对平行安装在可旋转平台上的天线组件。每个天线组件包括具有塑料匹配元件的两个子反射器。两个天线组件的输出与单个移相器耦合。组合的输出被重新发送到车辆内的接收器。卫星天线还包括用于接收频道选择数据和/或用于与车辆内的设备进行双向通信的接收机。天线，发射器和接收器由由风力发电机充电的存储装置自动供电。当天线不使用时，可伸缩天线罩降低到较低的轮廓。
