Abstract

An adapter to reduce the effects of cross phase communication between a PLC transmitter plugged into one of the L1 or L2 power lines of a home and a PLC receiver plugged into the opposite L2 or L1 power line includes a housing with one side configured as a 240 volt plug and an opposite side configured as a 240 volt, so that the adapter can be plugged into a 240 volt wall socket and a 240 volt appliance plugged into the adapter. A coupler or a repeater is in the adapter and extends between the L1 and L2 lines to reduce attenuation of a communication signal from the transmitter or alternatively to amplify the signal and send it on to the receiver. A high frequency filter can be interposed between the coupler and the 240 volt appliance to prevent noise from the appliance from entering the communication signal and for preventing communication signals from entering the appliance.
