ABSTRACT:
A radiating cable comprises a core having a center conductor bonded to, centered in, and supported by discs of dielectric material. A sleeve of dielectric material is extruded over the discs and thereby bonded thereto to form a plurality of sealed, coaxial, dielectric chambers. A tubular outer conductor is bonded in concentric relation to the sleeve. In a continuous process, at least one slot is formed in the outer conductor by a cutting operation and an outer jacket is extruded over the outer conductor. In a preferred embodiment, the outer conductor is made of an aluminum tube and two circumferentially equally spaced slots are formed therein by removing between 10 and 35% of the aluminum material. The width of the resulting slots may be configured so that a joint is formed in the slot between the insulating sleeve and the outer jacket, thus obviating the use of adhesive in bonding the outer jacket to the cable.
