ABSTRACT:
The invention describes a method and a device for communicating a signal over a power line. One embodiment may comprise a length of MV power cable that comprises a center conductor substantially surrounded by an insulator. A first concentric conductor is disposed external to the insulator over a first portion of the cable. A second concentric conductor that may have a length related to the wavelength of one or more carry frequencies of the data signals is disposed external to the insulator over a second portion of the cable and external to the insulator. A first gap is formed where the cable is exposed between the first concentric conductor and a first end of the second concentric conductor. A transceiver for communicating data signals over the MV power cable may be coupled to the first end of the second concentric conductor.
