- Sony FM-AM Stereo Receiver, 1976 - This device is one part of a component stereo sound system. Component stereos were built up over time through the purchase of individual components that best suited the needs of a user: receiver-amplifiers, tape decks, speakers, turntables, and CD players. This model reflected changing trends in sound reproduction, allowing audiophiles to upgrade outdated or broken components as needed.

- E.F. Johnson Company Antenna Insulator, 1936-1950 - Insulators--made of poor electrical conductors such as glass, ceramic, plastic, or composite materials--help make electric power and communication transmission lines safe. They isolate wires from utility poles, transmission towers, and buildings--structures that are made of conductive materials that could cause signal degradation, power loss, fire, or pose a shock hazard if the lines touched them.

- TWA Experimental Anti-Snow Static Loop Antenna, 1937 - Airport radio navigation beacons required pilots to listen for Morse code patterns to hold the correct course--notoriously difficult during storms. In 1936, Transcontinental & Western Air introduced an anti-snow directional antenna which could be used, in high-static situations, to "home in" on airport radio signals. This loop was housed in a sleek metal enclosure, protecting it from the elements.
