According to the 50 ohm RF cable manufactured by American TIMES PLMR standard, ultra-high foam polyethylene with a foaming degree of about 80% has low attenuation, small temperature coefficient and good stability against temperature changes. It is mainly used for wireless mobile communication, antenna feeder, microwave transmission, broadcast communication, etc. The base station transmitter, the connection between the receiver and the antenna or other high frequency areas as a low loss, low VSWR signal transmission line.
