A plug-in device is provided for adapting a building's electrical wiring system as an antenna for receiving radio or over-the air television signals. The device has a plug for insertion into an electrical receptacle in the building, a coaxial connector for providing the communication signal captured by the antenna to a signal receiver, and a plurality of conducting wires extending from the plug to the coaxial connector. The conducting wires comprise first and second wires, and a third wire in electrical contact with the coaxial connector. The first and second wires are electrically insulated from each other and from the third wire to prevent passage of alternating current (AC) power to the signal receiver. The wires are wound to inductively transfer the communication signal captured by the antenna to the third wire for output to the signal receiver via the coaxial connector.

A swivel arrangement including high voltage electrical swivels concentrically arranged around a common axis, each swivel including: a first annular housing part and a second annular housing part together defining an internal annular volume; a first solid electrical conductor stationary with respect to the first annular housing part, and a second solid electrical conductor stationary with respect to the second annular housing part, wherein the first and second electrical conductors are arranged within the internal annular volume for making conductive sliding contact with each other, wherein the first annular housing part and second annular housing part are rotatable relative to each other around the common axis while the first and second electrical conductors are in sliding contact with each other; wherein the swivels are arranged concentrically around the common axis so that a plane normal to the axis intersects at least two, preferably three, of the electrical swivels.

A short-circuit probe for short-circuiting an inner conductor with an outer conductor in a multiway coaxial plug includes an electrically-conductive contact spring comprising a holding and stabilizing section and a contacting section. The contacting section is bent and comprises an inner-conductor contact section and an outer-conductor contact section. A housing comprises: a receiving space; an inner-conductor insertion opening in a first end face, via which the short-circuiting inner conductor of the multiway coaxial plug can be inserted into the receiving space and can be brought into contact with the inner-conductor contact section; and a laterally and/or radially aligned outer-conductor contacting opening, wherein the outer-conductor contact section of the contact spring passes through the outer-conductor contacting opening and can be brought into contact with the outer conductor. The contact spring is arranged inside the receiving space and extends over a predominant length of the housing.
