Phase Couplers

The ZPCI series of Universal Inverting Phase Couplers is unique in many ways (patent pending). Unlike conventional phase couplers, multiple ZPCI units can be used in a home (e.g. one ZPCI per breaker panel). This is not the case for 'conventional' phase couplers where only one can be used per home. Two or more 'conventional' phase couplers will reduce (attenuate) signals, as will a mix of 'conventional' and ‘inverting’ phase coupler types.
