ABSTRACT:
There is provided a cable which retards lightning. The cable includes at least one internal conductor which may be a power conductor or a signal conductor. A choke conductor is wound about the internal conductor in the shape of a spiral. If lightning strikes near the cable or a device which is attached to the cable, such as an antenna, the choke conductor presents a high impedance to the current caused by lightning and will prevent the lightning current from flowing down the choke conductor, thus entering the internal conductor, thereby preventing damage to the internal conductor and any associated electronic equipment. Preferably, a shield is also spiraled wound about the internal conductor adjacent to the choke conductor in a direction opposite to the choke conductor, whereby the angle formed by the crossing of the choke conductor and the shield is approximately 90.degree. to block the magnetic field component of the lightning discharge.
