A coaxial transmission line for u.h.f. waves, and particularly for use with slotted line equipment, in which the center conductor is supported coaxially within the outer conductor by spaced dielectric pins extending radially between said conductors, wherein wave reflections are minimized by means of counter-bored areas in the form of shallow depressions in the surface of the inner conductor where it is engaged by said pins, said depressions completely surrounding the point of engagement of each pin with said inner conductor and being dimensioned to produce an inductive effect to compensate for the capacitive effect of the dielectric pins.

A. A coaxial transmission line comprising b. a rigid hollow outer conductor, c. a rigid inner conductor centrally located within the hollow outer conductor, said inner conductor having an outer surface, d. support means for rigidly supporting the inner conductor within the outer conductor comprising spaced dielectric pins extending radially between said conductors and which separately engage said inner conductor, and e. means for reducing wave reflections of at least one of said pins comprising a depressed area, in said outer surface, of said inner conductor, said depressed area being located in the same lateral plane of the inner conductor as said one pin and constituting a shallow depression in the outer surface of the inner conductor and extending longitudinally along said inner conductor, said depressed area extending laterally away from the pin for a distance which is small as compared to the periphery of the inner conductor and being dimensioned to produce an inductive effect tending to compensate for the capacitive effect of the dielectric pin.
