随着当今广播电视事业的发展,广播电视发射台站所发射的节目数量不断增加,而铁塔上挂载天线的位置又有限,天线的安装位置不足严重制约着发射节目数量的增加。多工器技术的日趋成熟及广泛使用,正好解决此问题。各发射台站技术人员掌握多工器的工作原理、维护,甚至能进行测试调试,对其发射台站的安全播出有着重要的意义。我台共发射六套调频节目,采用六工器通过开关板由双主馈管上一副天线。从2008年使用至今多工器稳定可靠,值得推广应用。
With the development of the radio and television industry at present, the number of programs transmitted by radio and television transmitting stations has been increasing. However, the position of the antenna on the tower is limited. The insufficient installation position of the antenna seriously restricts the increase of the number of transmitted programs. Multiplexer technology is increasingly mature and widely used, just solve this problem. The launching station technicians mastering the working principle, maintenance and even testing and debugging of the multiplexer are of great significance to the safe broadcasting of the launching station. I Taiwan launched a total of six sets of FM programs, the use of six-way switch board by the dual main feeder on an antenna. From 2008 to date, the multiplexer is stable and reliable, which is worth popularizing and applying.
