摘要
采取调整功率放大器工作状态 ,改变管型、天馈线等措施 ,进一步提高了GSZ 5差转机的发射功率和天线辐射效率 ,使其服务半径由 1 0km扩大到 2 7km。
This paper describes a practical method of technical rebuild of 50 W TV transposer system by replacing RF power tube ,main transmitting feeder and antenna for the purpose of extending its covering area.After rebuild the service radius is increased from 10 km to 27km.
