Coaxial cable refers to a cable with two concentric conductors, and the conductor and shielding layer share the same axis. It can be applied to the fields of cable television broadcasting, long-distance telephone transmission, short-distance connections between computer systems, and local area networks. After a series of development changes, coaxial cables have appeared many specifications and models to cope with different application conditions.

As a purchaser, how to choose a coaxial cable model? Pay attention to these aspects.
1. Choose according to working frequency
Generally, the connector of a coaxial cable will limit its maximum operating frequency, and the selection should be based on specific needs.
2. Choose according to transmission loss
Generally, the larger the diameter of the coaxial cable, the lower the density, and the lower the frequency, the lower the transmission loss, but the purchase cost will increase. Therefore, when choosing a coaxial cable, it must be considered based on actual conditions.
3. Choose according to power capacity
The power capacity of a coaxial cable is closely related to its heat dissipation capacity, and is generally inversely proportional. It should be selected according to the actual power capacity required, after all, the higher the power, the greater the cost.
4. Choose according to shielding performance
The shielding performance of a coaxial cable mainly depends on the structure of the outer conductor, and the shielding performance is different for different conductor structures. Generally, solid shielding is the best.
5. Choose according to resistance
Relatively speaking, it is relatively simple to choose the resistance of the coaxial cable, because in the application of the cable TV network, the resistance requirement of the coaxial cable is almost all 75 ohms, and the regular products can almost reach the standard.
