Part of Rugby transatlantic telephone transmitter

The telephone service between Britain and the USA began in January 1927 using radio transmitters and receivers working in the long-wave band. This is the only surviving part of the transmitter installed at Rugby Radio Station. It was designed by Standard Telephones and Cables Ltd in Britain and made pioneering use of the single-sideband system, which required less power and made more economical use of the waveband. It remained in use until about 1956.
