Abstract
A coaxial cable includes: a metallic inner conductor formed of a first material and having a first thickness; a dielectric layer circumferentially surrounding the inner conductor formed of a second material and having a second thickness; a metallic outer conductor circumferentially surrounding the dielectric layer formed of a third material and having a third thickness; and a polymeric jacket circumferentially surrounding the outer conductor formed of a fourth material and having a fourth thickness.

A coaxial cable, comprising:
- a metallic inner conductor formed of a first material and having a first thickness;
- a dielectric layer circumferentially surrounding the inner conductor formed of a second material and having a second thickness;
- a metallic outer conductor circumferentially surrounding the dielectric layer formed of a third material and having a third thickness;
- and
- a polymeric jacket circumferentially surrounding the outer conductor formed of a fourth material and having a fourth thickness;
- wherein the first material, first thickness, second material, second thickness, third material, third thickness, fourth material and fourth thickness are selected so that the cable has:
- (a) a usable bandwidth between about 5 MHz and the cut-off frequency of the cable;
- (b) a minimum bend radius of less than about 5 times the jacket outer diameter;
- and
- (c) a velocity of propagation of greater than about 88;
- (d) a return loss of at least about −25 dB;
- and
- (e) a nominal impedance of 75 ohms.
