7D-FB

7D-FB

The 50-ohm RF cable is made of ultra-high foaming polyethylene with a foam degree of 80%. It has low attenuation and small temperature coefficient, and has good stability to temperature change. It is mainly used as a low loss, low VSWR signal transmission line in wireless base stations such as mobile communication, antenna feeder, microwave transmission, broadcasting communication and other systems base stations, and the connection between receiver and antenna or other high frequency fields.
