The coaxial RF cable is widely used on telecommunication networks.
Represents a wire of the cylindrical form with two conductors from metal in it, the internal rod and external the screen. The distance inside densely is filled with an isolation material which safely fixes an immovability of conductors. And the electromagnetic energy passing in an interval from an internal conductor to external, is protected from noises by the screen that allows to achieve transmission of broad range of quality signals.
