Abstract
An apparatus for coupling a source of signals to a receiver having a ground return electrically coupled to the AC line and for providing immunity from interfering ambient signals. The apparatus includes a coaxial transmission line surrounded at both ends by feedthrough capacitor coupling the outer conductor of the transmission line to the ground return of the signal source. A toroidal ferrite member also surrounds the transmission line between the feedthrough capacitors thereby reducing the current flowing in the outer conductor and the resulting direct pickup of ambient signals.
