确定角度前检查设备为了使安装调试工作少走弯路,调整天线前最好能将制作好的卫星电视接收机,先用别人已安装调试好的天线检查是否工作正常。如接收机有故障应先将其排除。这样会省去许多调节时遇到的麻烦。专门为用户进行安装服务的专业安装人员,也可以带一个便携式卫星电视彩条信号发生器到现场去。这种仪器带有一个小天线,当它指向反射面时可以在电视上看到彩条。如果看不到这些彩条,就应该采取一些基本的技术手段,用这个信号发生器来判断故障所在。如果
Determine the angle before the inspection equipment In order to make the installation and commissioning work less detours, the best antenna before making a good satellite TV receiver, with someone else has installed a good antenna to check whether it is working properly. If the receiver is faulty, it should be excluded first. This will save the trouble of many adjustments. Professional installers who specialize in installing services for users can also bring a portable satellite TV color strip signal generator to the site. The instrument has a small antenna that sees the color bar on the TV when it points to the reflective surface. If you can not see these color bars, you should take some basic technical means to use this signal generator to determine the fault. in case
