Cable components are composed of coaxial cables and coaxial connectors. RF cable components can be divided into semi steel, semi flexible, flexible/ultra flexible types, and can be selected according to their characteristics as needed: 1. Half steel type: excellent concealment effect, but with a small bending radius and high hardness, it cannot be manually formed; 2. Semi flexible: with good concealment effect but small bending radius, it can be manually formed but does not rebound; 3. Flexible/ultra flexible: able to adapt to relative displacement scenarios, with relatively large bending radii.

Coaxial cable, also known as coaxial, is used to transmit radio frequency (RF) signals. It has low emission losses and provides protection against electromagnetic interference, allowing the low power consumption of the signal to be transmitted over longer distances. A coaxial cable consists of a core, insulation, shielding, and casing. This is what is called coaxial cable, because these chapters all have the same axis. There are many different types of coaxial cables, each designed with different physical and electronic characteristics for specific tasks. This is commonly used to execute cable TV signals along suburban streets and homes. Coaxial cables are used to transmit television signals and connect video devices together. It can also be used for radio signals and connecting receivers, transmitters, and antennas together. Short length coaxial cables are also used to connect equipment and testing equipment, such as signal generators. Coaxial cables were once widely used to connect computer local area networks (LANs), but have replaced twisted pair cables. However, wired broadband is still popular and uses the same coaxial cable for the purpose of cable television networks. Most coaxial cable networks will eventually replace fiber optic networks.

The difference between SYWV coaxial cable and SYV RF coaxial cable: 1. The execution standards of the two are different, that is, the electrical parameters are different, and the attenuation of SYWV cables with the same specifications is relatively small. 2. The cable structure dimensions are different. Due to the foaming structure of the insulation medium of SYWV cables, which has a relatively small dielectric constant, the inner conductor sizes of the two types of cables are different. 3. The production process is different. Generally, SYWV cables use physical foaming (low-end products use chemical foaming). 4. As for the form of the outer conductor, copper, aluminum magnesium alloy, copper clad aluminum, and so on are all made according to needs and can be made the same. 5. There are differences in application scenarios and performance. SYV cables are generally used for welding inner conductor joints (with better welding performance) and short distance transmission. This cable is simple and can be made with extrusion equipment. 6. The characteristic impedance of the cable (50 ohms/75 ohms) can be achieved according to user requirements.
