Patent Images
1. A method for electrically coupling high frequency communication signals between a first power line and a second power line comprising the steps of:
- a) providing an outlet, said outlet having a first receiving slot electrically connected to said first power line and a second receiving slot electrically connected to said second power line;
b) making electrical connection to said first power line by inserting a first power prong into said first power prong receiving slot;
c) making electrical connection to said second power line by inserting a second power prong into said second power prong receiving slot; and
,d) electrically coupling said first and said second power prong such that said communications signals comprising high frequency alternating current pass at low impedance and low frequency alternating current passes at high impedance between said first and said second power lines.

Abstract
A coupler providing coupling for power line communications between the power lines carrying different phases of the power. The coupler engages an ordinary wall outlet such as a 220 volt outlet and includes a receptacle for a 220 volt plug. Internally, the adaptor has high frequency coupling between the power lines. The coupling presents a high impedence to the power signal.
