SSF-141 Semi-Flexible Coaxial Cable Ø4 mm is a high-precision semi-flexible high-frequency coaxial cable designed for applications where minimal signal loss, high phase stability, and operation at ultra-high frequencies up to 34 GHz are critical. Thanks to the combination of a silver-plated copper inner conductor, a PTFE dielectric, and an FEP outer jacket, the cable provides stable electrical characteristics even in demanding RF environments.
SSF-141 Coaxial Cable is widely used in measurement systems, laboratory setups, telecommunications nodes, mobile networks, and precision RF interconnections where parameter repeatability and minimal phase distortion are required.
