Television Terminals for Coaxial Systems

THE broad features of the operation of the L-1 coaxial system for the transmission of television have been public for more than a year,1 but thus far the factors influencing the design of the coaxial television terminals and a detailed discussion of the equipment now in service in the Bell Systems' television network have not been published. The television terminals here described were placed into network service in 1947, but in basic form are similar to experimental models developed prior to the war and used in early television transmission studies over the coaxial cable.2,3
