Termination by Means of Coupled SectionsAuthor: Edmund A. Laport Standing waves on a feeder can be suppressed by means of an open-end quarter-wave section or a half-wave short-circuited section coupled to the feeder ( and ) provided that the position of the coupled section along the line is correct, as well as the degree of coupling to the feeder.
The open end of the quarter-wave coupled section is pointed toward the load end of the feeder, and the standing waves are eliminated on the feeder opposite the closed end of the coupled section. The schematic diagram of this arrangement is given in Fig. 4.41.
