Abstract
A directional coupler for coaxial cable, or the like, wherein the portions of the lines to be coupled are positioned to run next to each other, thereby defining a gap between them that is in a plane that extends generally parallel to the planes of the lines connected. For adjusting coupling attenuation, the gap width is changed by moving the overlying sections of the lines in a direction perpendicular to the axes of the connection lines.
