An element in a transmission line network consists of two short, open-ended stubs which are attached to a transmission line at a single station on that line and are of the same characteristic impedance as the line. The stubs act on a passing wavefront in the line to: first, reduce the forward voltage for the momentary duration of the two-way transit time within the stubs; then, to restore the forward voltage completely and without ringing. With the addition of high-input-impedance amplifiers, an improvement in communication branching is obtained and, with the addition of double-pole single-throw switches, an improvement in switching-tree performance is obtained.
