Abstract
Abstract A segment of a main transmission line is located equidistant between and parallel to a first and second coupling segment. The first coupling segment has an input terminal at one end thereof for connection to a stub line. The second coupling element has a terminating impedance located at the end thereof opposite said input terminal end of said first coupling segment. A conductor connects the other opposite ends of said first and second coupling segments so that a pulse travelling thru said main line segment or said first coupling segment in a direction away from said input terminal end of said first coupling segment will couple to the other travelling in the reverse direction.
