Abstract
Abstract The bending life of coaxial cable with a helically corrugated copper outer conductor is greatly increased, without impairment of other important mechanical or electrical characteristics, by employing specific relations of corrugation pitch and depth to each other and to overall cable diameter.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
91 words
In a coaxial cable comprising an inner conductor, a foam dielectric surrounding the inner conductor, and a helically corrugated copper outer conductor surrounding the dielectric, the improved construction having the ratio of the corrugation depth to the corrugation pitch of the copper outer conductor substantially in the range of 0.55 to 0.70 with the copper outer conductor having a ratio of thickness to corrugation pitch between 0.05 and 0.20 and having a ratio of outer diameter to pitch at least equal to 3.5, and having an inner conductor of stranded wire.
Claim 2
Dependent Claim
91 words
