Abstract
Abstract An arrangement for wide band inductive coupling of a coaxial line to a hollow conductor, by means of a coupling loop having a first leg extending in axial direction from the inner conductor of the coaxial line into the hollow conductor, and a second leg extending transversely from the first leg to the wall of the hollow conductor, with the free end portion of such first leg projecting beyond the second leg into the hollow conductor, at least two adjustable pins being provided for determining the coupling characteristics which pins extend inwardly from the hollow conductor sidewall, one of such pins being disposed opposite the first leg and extending inwardly toward the latter, while a second of such pins is disposed adjacent to but axially spaced from the projecting portion of the first leg.
