How do I know what type of coax cable I have? 1.The price is cheap Compared with other ordinary cables, the price ofLRM200 RF Coaxial cables is cheaper, its price is cheaper than other cables, and the weight ofLMR400 RF Coaxial Cable is lighter, more convenient to transport, and its transportation cost is lower . 2. Suitable for large projects RG58 RF Coaxial Cables has good oxidation resistance and corrosion resistance. If it comes into contact with oxygen in the air, it will react quickly and form an oxide film. With this film, it can prevent internal oxidation and corrosion. Corrosion, so it is suitable for use in large projects. Therefore, in outdoor projects, this LMR240 Coaxial cables is very suitable for high-voltage projects and overhead Transmission projects because of its cold resistance, high temperature resistance, waterproof, sun protection, and anti-corrosion.
