Abstract
The invention provides a method and a device for communicating a signal over a power line. One embodiment may comprise a length of power cable that comprises a center conductor substantially surrounded by an insulator. A concentric conductor is disposed external to the insulator over a first portion of the cable. A coupling conductor may be disposed concentrically around a second portion of the cable external to said insulator and having a first end and a second end. The concentric conductor is absent in a manner to form a gap between the concentric conductor and the first end of said coupling conductor. A transceiver cable is coupled to the first end of said coupling conductor and a common mode choke may be disposed substantially around the entire circumference of a portion of said coupling conductor. Finally, the second end of the coupling conductor may be coupled to ground through a convenient neutral conductor.
