给卫星接收机通上电源,接收机面板上的指示灯或显示屏应有指示,在接收机与电视机之间连接好AV线或射频线,打开电视机,画面上应有雪花状噪波点。然后一人调天线,一人调卫星接收机。调整天线分三步:第一步调整天线(馈源)的极化方式。地面接收天线(馈源)的极化方式是以地平面为基准,馈源矩形波导口窄边垂直于地平面的 Turn on the power to the satellite receiver, indicator light or display on the receiver panel should be instructed, AV cable or radio frequency cable connected between the receiver and the TV, turn on the TV, the screen should have snowflake-like noise point. Then one person tune the antenna, one satellite receiver. Adjust the antenna in three steps: The first step is to adjust the polarization of the antenna (feed). Ground receiving antenna (feed) polarization is based on the ground plane, the feed rectangular waveguide narrow side perpendicular to the ground plane
