www.idc-online.comuninsulated conductors that remain entangled with one another. The insulating spacer of the cable is further surrounded by a sheath that is cylindrical in shape. The final circle is formed by an insulating jacket. The insulation surrounding the RG-58 cable carries a low impedance of around 50 or 52 ohms. It is generally used for
