Coaxial cable

In 1931, the invention of coaxial cable was issued a U.S. patent for the first time in the U.S., described as a "concentric conducting system". The inventors were Lloyd Espenschied of Kew Gardens, N.Y. and Herman A. Affel of Ridgewood, N.J. The patent was assigned to the American Telegraph and Telephone Co. of New York City. (No. 1,835,031). The application was television, for which a wide range of transmision frequencies is required. Whereas individual channel requirements for telegraphy are of the order of a few hundred cycles at most, and telephony perhaps a few thousand cycles, television requires bands of hundreds of thousands of cycles in width to ensure a reasonable degree of picture detail. A single pair concentric conductor arrangement is used.
