With the advent of metropolitan CATV systems utilizing expanded bandwidth, the area covered by a single headend is reduced. Consequently, to cover the required area sub-headends or hubs are established. 'Microwave radio (particularly AML) is one of the more cost effective ways to transport signals to hubs. However, in most metropolitan areas, several paths must be considered before a final selection can be made. The path profile is perhaps the most tedious task of the preliminary engineering, taking one to two hours of an engineer's time per path. The BASIC computer program described uses a microcomputer with 16K bytes of memory and a DOT MATRIX printer to generate path profiles in minutes rather than hours.
