Optimized symmetrical coaxial cable
First Claim
1. A symmetrical coaxial cable, comprising:
- a core having an axis;
a braided inner conductor constructed of a first quantity of wire strands, the first quantity of wire strands disposed along said core at an angle of approximately eighteen degrees with respect to the axis of the core, said core supporting said inner conductor;
means for insulating said inner conductor, said means for insulating disposed along said inner conductor;
a braided outer conductor constructed of a second quantity of wire strands, the second quantity of wire strands disposed along said means for insulating at an angle of approximately thirty eight degrees with respect to the axis of the core; and
means for protecting said inner and outer conductors from atmospheric elements disposed along said outer conductor;
wherein said cable having a 5;
6 overall ratio between the quantity of strands in said inner conductor and the quantity of strands in said outer conductor;
wherein said quantities of strands in said inner conductor and in said outer conductor and the angles that said inner conductor and said outer conductor are disposed at are chosen in order for said inner conductor and said outer conductor to have matching series impedances.

Abstract
A coaxial audio cable is provided having a core, braided inner and outer conductors, dielectric layer between the inner and outer conductor and a jacket surrounding the outer conductor. The inner conductor is disposed around the core at a braid angle of approximately eighteen degrees. The dielectric layer is wrapped around the braided inner conductor. The outer conductor is disposed around the dielectric layer at a braid angle of approximately thirty-eight degrees. The cable is designed to provide a 5:6 overall ratio between the number of strands in the inner conductor and the number of strands in the outer conductor. The inner and outer conductors of the coaxial audio cable are designed to have matching series impedances.
