What are Coaxial Cable types? LRM200 RF Coaxial cables is a cable composed of two concentric conductors. LMR240 Coaxial cables, RG174 Cables are mainly used in communications and cable TV. Between the conductor and the shielding layer, the axis used is the same.LMR400 RF Coaxial Cable is made of four layers of materials, mainly: conductive copper wire, a layer of plastic, a layer of thinner mesh conductors, and outer skin. At present, the process ofRG58 RF Coaxial Cablesis gradually With progress, some such wires with relatively large bending amplitudes have also appeared. It is recommended to use such wires with traditional copper tube outer conductors as much as possible in places where flexibility is not high to ensure stability.
