Radiating coaxial cable
First Claim
1. A radiating cable comprising:
- a central conductor;
a plurality of coaxial dielectric members connected to and spaced along the length of said central conductor;
a first dielectric sleeve concentrically enclosed around said plurality of dielectric members, said dielectric members and said sleeve defining a plurality of air chambers therebetween;
a radiating sheath concentrically formed on said dielectric sleeve, wherein said radiating sheath includes at least one continuous slot or gap extending along the length thereof; and
a second dielectric sleeve concentrically formed on said radiating sheath, wherein said second dielectric sleeve occupies the space formed by said slot or gap and is bonded to said first dielectric sleeve thereat.

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.
