Best Frequency Assignments For Mid And Super Band Channels (1970)

By Michael F. Jeffers, Jerrold Electronics Corporation

During the past two decades CATV systems have carried, first, three channels of television; then five channels, then twelve channels.

For the past three years we have been advocating twenty to thirty television channels with thoughts of an almost limitless capacity for the future use of cable spectrum. As systems expanded from three to twelve channels the frequency allocation was obvious - we simply duplicated standard VHF television assignments. With the increase in the number of channels beyond twelve, serious consideration must be given to their precise frequency assignment. The purpose of this paper is to discuss some of the problems that might be encountered and to suggest ways of minimizing their effect.
