Abstract
A tapered wiring harness is disclosed for an array of hydrophones with spaced take-out points on the harness at which a signal wire and a ground wire are connected with a hydrophone. The harness comprises a bundle of signal wires, which diminish in number from one end to the other, and it also comprises a ground wire and a strain cord, which extend throughout the length of the harness. The bundle of wires and the strain cord are held in a bundle of substantially circular cross-section by a lacing of thread formed as a sewing machine stitch of the zig zag type. Hairing members of uniform length are secured to the bundle under the lacing at predetermined intervals with the hairing more closely spaced on the larger diameter of the bundle. In another embodiment, the hairing members are spaced uniformly but are of variable length with longer members on the larger diameter of the bundle.
