A distributed-parameter delay line comprises a rod or tubular core of insulating material, e.g. ceramic or paper, a conductor wound helically around the core, a narrow lamellar conductor extending along the core either inside or outside the winding and a strip of dielectric foil between the winding and the conductor, the width of the strip being less than the outer circumference of the core. The ratio of the width of the lamellar conductor to the circumference of the core preferably exceeds 1: 8. A tubular screen may surround the winding and may be connected to the lamellar conductor which forms an earth. The helical winding may be subdivided, the length of each section being small compared to the wavelength at the upper cut-off frequency. The thickness of the dielectric foil (#0À1 mm.) must be accurately controlled and this may be done by passing the foil through a slot formed between a rotatable cylindrical milling tool and an adjustable, fixed support.
