A cable coupling transformer comprises a metal or ferrite former defining separate high permeability portions of a pair of flux paths, a winding electromagnetically associated with each high permeability portion, and a common low permeability por- tion of each flux path which passes between a pair of conductors carrying equal currents in antiphase. A portion of the current induced in either the conductors or the windings are impressed on the other to create a simple communications device.
