20m X-Band ANTENNA (OEM)

概观

 

20M天线系统采用CAD设计和制造,可应用于最新更新的INTELSAT(IESS)标准A地球站。

20M天线系统包括双形状卡塞格林反射器,带波纹喇叭的频率重用馈电网络,用于极限运动的仰角方位限制运动主柱基座或用于全运动的转盘安装座。反射器的备用结构,连接主反射器和底座的基座以及基座提供了正常操作所需的保证指向精度。

主反射器直径包括精密拉伸成型铝板,铆接环和三个环中的径向。

天线系统具有高增益,低旁瓣,低交叉极化的特点,能够在发射和接收频带中进行频率重用,具有高分辨率角度位置显示的高驱动/控制精度。

辐射方向图符合INTELSAT(IESS),FCC和CCIR对地静止卫星2度间隔位置的相关要求。
