US Patent 7046124 Power line coupling device and method of using the same

The coupler of the present invention couples broadband RF signals to and from a power line conductor. The coupler of one embodiment that is for use with overhead power lines includes a length of URD MV cable with the neutral conductor removed and that is communicatively coupled to a MV power line at each end on opposite sides of a low pass filter. A radio frequency choke is communicatively coupled to URD MV cable between first and second coupling capacitors. The semi-conductive jacket of the URD cable may be coupled to ground via a low frequency conductive path.
