The band-pass filter portion of a coaxial cable includes filter elements in the form of a laminate of dielectric material having a conductive layer on opposite faces. Attached to each conductive layer is a mass which is the electrical equivalent of a shunt capacitor. Each such mass is joined to a center conductor. A sleeve of dielectric material surrounds each center conductor except in the area of the filter. A seamless tube of dielectric material surrounds the filter elements and the dielectric sleeves. A monolithic jacket of electrically conductive metal surrounds said seamless tube. |
