随着我国社会经济的不断进步,我国的科学技术取得了长足的发展,我国广播电视所用到的无线发射台的应用范围也在不断的扩大。在广播电视中保证无线发射台安全播出的关键环节就是要维护好无线发射台的天馈线系统。中波天馈线的传输路线、匹配度、结构、传输地形地质、地网优劣及传输地导系数等各方面均会对我国的全顾固态中波发射机的工作状况产生较大的影响。所以为了更好的保证我国无线发射台的安全播出就必须要加对中波天馈线系统的技术维护与技术管理,从而有效地增强无线广播电视的接收质量及扩大无线广播电视的接收范围。
With the continuous social and economic progress in our country, great progress has been made in science and technology in our country. The scope of application of radio transmitting stations used in radio and television in our country is also constantly expanding. In radio and television to ensure the safety of wireless launchers broadcast a key link is to maintain a good wireless transmitter antenna system. The transmission line, matching degree, structure, transmission topography and geology, the advantages and disadvantages of the ground network and the transmission guide coefficient of the antenna of the medium-frequency antenna feeder all have a great impact on the working conditions of China’s all-solid-state solid-state transmitter. Therefore, in order to better ensure the safety of China’s wireless transmitting station, it is necessary to increase the technical maintenance and technical management of the antenna feeder system so as to effectively enhance the receiving quality of the radio and television broadcasting and to expand the receiving range of the radio and television broadcasting.
