Simply Automated Universal Inverting Coupler

Phase couplers boost powerline signals by providing a bridge between the two, 120 VAC electrical phases (A and B) in a split- phase, 240 VAC home. Without a phase coupler signals travel out to the street-side transformer on one phase and comeback in the home 'inverted' on the other phase; usually at a lower (attenuated) level. In homes up to 2000 Sq. Ft. and within 100 feet of the transformer, phase coupling may not be needed for UPB. However, as the size of the home and distance from the transformer increase, phase coupling becomes more important.
