Coaxial Communication Transmission Lines

A nonmathematical discussion of the mechanism whereby energy may be transmitted over long distances at high frequencies by the use of ``coaxial conductors´´ is presented in this paper. A coaxial system consists of a cylindrical conducting tube within which a smaller conductor is coaxially placed. Such conductors, which reduce interference and cross-talk are applicable for the transmission of telephone, telegraph, and television signals over a very wide range of frequencies.
