盘锦315台并馈式中波自立塔发射天线(SFA)为省内首座并馈式自立铁塔中波天线,属于中波广播发射先进前沿技术。在这担心和自豪并存的期待下,已安全运行了一年半时间,我们得到了满意答案:无论天馈线系统的稳定性,还是防雷保护系统的保障作用,都经受住了时间和空间的考验。结果表明,与原有的拉线塔相比,辐射场的强度加大了,覆盖范围也达到了设计目的。它的结构形式、优势特点和应用前景,为今后中波转播台站的改造或迁建提供了参考,相信(SFA)会因其优势而得到更为广泛地应用。 Panjin 315 feeder and medium-wave self-supporting tower transmitting antenna (SFA) is the province’s first self-feeding tower self-supporting tower antenna, which belongs to the advanced technology of medium wave broadcasting. With this fearful and proud coexistence of expectations, we have been operating safely for a year and a half. We have been satisfied with the answer: no matter the stability of the antenna feeder system or the protection function of the lightning protection system, we have endured the time and space test. The results show that compared with the original cable tower, the intensity of the radiation field has been increased, and the coverage has also reached the design goal. Its structure, advantages and application prospects provide reference for the transformation or relocation of the China Central Television broadcasting station in the future, and it is believed (SFA) will be more widely used due to its advantages.
