Coaxial cable

Solid polyethylene insulated radio frequency cables are cables that transmit electromagnetic energy within the radio frequency range. Radio frequency cables are indispensable components in various radio communication systems and electronic equipment, and are widely used in wireless communication and broadcasting, television, radar, navigation, computers and instruments, etc. There are two commonly used types of RF coaxial cables: 50Ω and 75Ω RF coaxial cables. Rf coaxial cables with a characteristic impedance of 75Ω are often used in CATV networks, thus they are called CATV cables. Their transmission bandwidth can reach 1GHz. Currently, the transmission bandwidth of commonly used CATV cables is 750 MHZ.

Physical foamed polyethylene insulated coaxial cables for cable television systems are suitable for main lines, branch lines, user lines and other electronic devices used in cable television systems.
