电子工业部第39研究所生产的后馈式6米卫星接收天线在全国分布较广,特别是县一级的卫星地面收转站使用得较多。一般情况下,天线内的高频头是能长期稳定地工作的,但如遇严重雷击等突发性事故时,高频头内的电源部分较容易损坏。高频头结构精密,使用的是微波器件,加之又缺乏图纸资料和仪器,所以,维修起来较为困难。现把我们在维修实践中积累起来的部分数据列 The 39th post-feed type 6-meter satellite receiving antenna produced by No. 39 Institute of the Ministry of Electronics Industry is widely distributed throughout the country, especially at the county-level satellite ground receiving stations. Under normal circumstances, the antenna within the high-frequency head is able to work long-term stability, but in case of serious accidents such as lightning strikes, the power part of the high-frequency head more easily damaged. High-frequency structure of the first sophisticated, the use of microwave devices, coupled with the lack of drawings and equipment, so it is more difficult to repair. Now we have some data accumulated in the maintenance of the data column
