摘要
为了保障发射信号不间断、高质量、既经济又安全的有效播出,高山发射台通常需要备用的供电、信号源以及发射机。而天线的故障概率比较低,并且受到天线铁塔位置的制约,使用备用天线的高山台不多。但是为了确保安全播出,备用天线仍是非常有必要的。为此,本文着重介绍高山发射台广播电视发射机的备用天线改造方案设计与实施细节,为其他台站进行天线改造提供参考。
In order to ensure the uninterrupted,high-quality,economical and safe effective broadcasting of transmitted signals,alpine transmitting stations usually need backup power supply,signal source and transmitter.However,the failure probability of the antenna is relatively low,and restricted by the location of the antenna tower,there are not many high mountain stations using spare antennas.However,in order to ensure safe broadcasting,it is still very necessary to have a spare antenna.Therefore,this paper focuses on the design and implementation details of the backup antenna transformation scheme of the radio and television transmitter of Gaoshan transmitting station,so as to provide a reference for other stations to carry out antenna transformation.
