Coaxial cables are prized for their ability to carry high-frequency signals with minimal loss and interference, they are commonly used in television and internet services. Additionally, coaxial cables are used in connecting radio equipment, such as antennas and transmitters, due to their ability to handle the frequencies used in these communications.

RF cable, also called coaxial cable, is a wire and signal transmission line. RF cable is an indispensable component of various radio communication systems and electronic equipment. Widely used in wireless communications and broadcasting, television, radar, navigation, computers, and instruments.

Coaxial cable can transmit digital signals, can also transmit analog signals. What is the specific signal depends on the way the cable station uses what transmission, impedance is generally 75 ohms, only suitable for close distance transmission of image signals, when the transmission distance reaches about 200 meters, the image quality will be significantly reduced, especially the color.
