射频同轴电缆是中小型电视差转台中常用的馈电设备。但在实际工作中。常会遇到用射频同轴电缆开路或短路馈线做自制天线匹配网络问题。为了使天馈系统能长期保持良好的匹配,务必要对电缆的各端头进行密封防潮防水处理。这种固体介质同轴线,在它的内外导体之间填充
RF coaxial cable is commonly used in small and medium-sized TV turntable feed device. But in actual work. Often encounter with RF coaxial cable open or short-circuit feeder to do home-made antenna matching network problems. In order to make the antenna system to maintain a good long-term match, be sure to seal the end of the cable moisture-proof waterproof. This solid dielectric coaxial line is filled between its inner and outer conductors
