ABSTRACT:
A system for decreasing high frequency (HF) radiation emission in a power line comprises a first transmitter configured to transmit a utility power signal over the power line. A second transmitter transmits a high frequency communication signal over the power line so as to provide a combined utility and high frequency signal. A plurality of modulators, each of which provides a differential output signal to at least two phases of the power line such that the same high frequency data signal is transmitted via at least two phases of the power transmission line in an out-of-phase arrangement.
