Abstract:
1. A power line communications coupling device for communicating data signals over an underground power line cable comprising a center conductor, a concentric insulator disposed external the center conductor, and a concentric conductor disposed around the circumference of the power line cable external to the insulator over a first portion of the power line, and wherein the power line cable is configured to carry a power signal having a voltage greater than one thousand volts, the device comprising: a coupling conductor having a first end and a second end and disposed substantially around the circumference of the cable at a second portion of the cable where the concentric conductor is not present; a gap formed between the concentric conductor and said first end of said coupling conductor; wherein a third portion of the cable extends from said second end of said coupling conductor where the concentric conductor is not present; and a communication device communicatively coupled to the coupling conductor.
