由机械电子工业部第三研究所承建的海军司令部大院电视共用天线系统工程已通过验收。该工程主要特点有: 1.工程位于北京市区公主坟。整个系统采用V/U全频道传输,工作频率范围45MHz～860MHz。2.系统设计传送电视节目18套,最高频道采用50频道(814MHz)传输。3.系统可接收北京地区电视广播节目、卫星广播节目、自办电视节目,并具有现场直播及其它功能。4.系统设计不仅满足了目前使用要求,而且还着重考虑了北京新电视发射塔开播后(接收距离1.7公里,接收场强约117dBμV)的使用条件,采取了有效的技术措施。
The Nanyang Command Center compound television antenna system project, constructed by the Third Institute of the Ministry of Machinery and Electronic Industry, has passed the acceptance test. The main features of the project are: 1. The project is located in Gongzhufen, Beijing. The entire system uses V / U full-channel transmission, the operating frequency range of 45MHz ~ 860MHz. System design 18 sets of transmission television programs, the highest channel using 50 channels (814MHz) transmission. 3. The system can receive television programs in Beijing, satellite radio programs, television programs run by themselves, and has live and other functions. 4. The system design not only meets the current requirements, but also considers the conditions for using the new TV tower in Beijing (receiving distance of 1.7km and reception field strength of 117dBμV) and adopting effective technical measures.
