本产品的特点是功率大、驻波比小。尤其是驻波比,出厂指标1.17,实际可达1.13。同时具有体积小、重量轻、结构简单、使用方便之优点。这种装置适用于陆地、坑道、船舶、航空、广播电台等发射系统,在天线与馈线、馈线与发射机之间进行阻抗转换,起到系统各接口环节之间的阻抗匹配作用,实现最佳功率传输,从而可提高短波通信的质量和效果。主要技术指标是:工作频率:3～30MHz;峰包功率:30kw;驻波比:≤1.17;效率:≥95％。 This product is characterized by large power, small standing wave. In particular, standing wave ratio, the factory index 1.17, the actual up to 1.13. At the same time has the advantages of small size, light weight, simple structure, easy to use. This device is suitable for transmitting systems such as terrestrial, tunnel, ship, aviation, radio station and so on. The impedance conversion between the antenna and the feeder, feeder and transmitter serves as the impedance matching between each interface of the system to achieve the best Power transmission, which can improve the quality and effectiveness of shortwave communications. The main technical indicators are: Operating frequency: 3 ~ 30MHz; peak package power: 30kw; VSWR: ≤ 1.17; Efficiency: ≥ 95%.
