Classification of coaxial cables
According to the different insulation medium, the inner and outer conductors are divided into:
Foam insulated cables: The insulator of the foam insulated cables is made of physical foamed polyethylene materials; foam insulated cables are generally used in the telecommunications industry.
Foam insulated radio frequency coaxial cables are divided into transmission cables and leaky coaxial cables (LCX, Leaky Coaxial cable) according to their transmission properties. Transmission cables are ordinary feeders, mainly used for RF signal transmission, while leaky cables have hundreds or thousands of small holes (or slots) on their outer conductors. These holes correspond to numerous RF emission points, so that the power can be Multi-point radiation along the cable, which integrates signal transmission and signal transmission and reception functions. It has the dual function of coaxial cable and antenna. It is specially used for some roads, railway tunnels, subways, buildings, mines, large exhibition halls or airports. Areas where wireless signal propagation is limited and difficult to cover. Currently, foam insulated radio frequency coaxial cables are mainly used as radio frequency signal transmission cables for cellular mobile communication systems such as GSM, CDMA, UMTS, LTE, etc. In addition, there are also other applications, such as the connection between antenna arrays and radio frequency. Connection or jumper between equipment and indoor coverage system...
