摘　　要：广播电视行业中,发射天线技术对节目播出效果具有直接影响,为了保证节目质量,需要做好技术维护工作。以广播电视发射天线技术为切入点,应用该技术能够保证信号传输安全,并减少发射工作量。以此为基础,结合广播电视发射天线技术常见的天线故障、反射损耗、驻波比故障等提出维护对策,从而为相关工作者提供参考。In the radio and television industry, the transmitting antenna technology has a direct impact on the broadcast effect of the program. In order to ensure the quality of the program, it is necessary to do a good job in technical maintenance. Taking the radio and television transmitting antenna technology as the starting point, the application of this technology can ensure the safety of signal transmission and reduce the transmission workload. Based on this, combined with the common antenna failure, reflection loss, standing wave ratio failure, etc. of radio and television transmitting antenna technology, maintenance countermeasures are proposed, so as to provide reference for relevant workers.
