非标准场地条件下中波小天线系统改造与应用

Transformation and Application of Small MW Antenna System in Non-standard Site Conditions

某甲中波台在新建自立式双锥中波小天线时,因场地区域限制,传统地网无法正常铺设,地网半径仅为15m,无法满足覆盖要求。为此,我们采用架空平衡网代替传统地网,以提高覆盖;同时,为进一步改善天调网络工作条件,加强天调室通风散热,合理利用土地,尝试在塔下建设新型天调室,取得了良好的效果。

When a new self-supporting double-cone MW small antenna is built in a WM station, traditional ground network can not be laid normally due to the limitation of site area, and the radius of ground network is only 15 meters, which can not meet coverage requirements. Therefore, an overhead balance network is used instead of traditional ground network to improve coverage. At the same time, in order to further improve working conditions of blend network, strengthen ventilation and heat dissipation of blend room, and make rational use of land, a new type of blend room is attempted to be built under the tower, which has achieved good results.
