Abstract
The coupler of the present invention includes a plurality of core members that are disposed between the semi-conductive ground jacket and neutral conductor of a standard URD MV cable. The core members are series wound by a transformer conductor, which forms a secondary winding that is coupled to the primary of a transformer, which provides impedance translation and/or isolation. The secondary of the transformer is coupled to a connector for communicating data signals through the coupler.
