Dual leaky cables
First Claim
1. A dual leaky coaxial cable comprising:
- (a) a pair of parallel elongated conductors,(b) separate dielectrics surrounding each of the conductors,(c) separate first external conductive shield means surrounding each of the dielectrics, each shield means containing a gap through which an electric field can leak,(d) separate second external shield means surrounding each of said first external shield means, having substantially circular cross-sections, and defining second external shield means diameters of similar size,(e) means associated with the first and second shield means for selectively coupling magnetic fields surrounding each of said elongated conductors in the presence of a propagating signal through the first and second external shield means, and(f) means adjacent both said second shield means for maintaining the individual respective second external shield means separated from each other by a distance which is a fraction of the diameter of one of the second external shield means.

Abstract
A dual leaky coaxial cable comprising a pair of parallel elongated conductors, a dielectric surrounding each of the conductors, separate first external conductive shield apparatus surrounding at least the major portion of each of the dielectrics, separate second external shield apparatus surrounding each of the first external shield apparatus, apparatus associated with the shield apparatus for selectively coupling magnetic fields which may surround each of the elongated conductors through the first and second surrounding external shield apparatus, and apparatus for maintaining the individual respective second external shield apparatus separated by a distance which is a fraction of the diameter of either of the second external shield apparatus.
