The coaxial cables 104, 106, 108 may comprise any suitable type of coaxial cable, such as a cable comprising a center conductor 110, a dielectric 112 surrounding the center conductor 110, and a shield 116 covering the dielectric 112. In one embodiment, the shield 116 of the coaxial cables 104, 106, 108 remains at least partially exposed along a length of the cable assembly 100. In a second embodiment, the shield 116 of the coaxial cables 104, 106, 108 is exposed along the entire length of the cable assembly 100. The shield 116 comprises an electrically conductive surface running the length of the cable assembly 100.

The coaxial cables 104, 106, 108 may be arranged within the outer jacket 102 such that electrically conductive surface of each shield 116 of each coaxial cable 104, 106, 108 is in direct contact 302 with the electrically conductive surface of least one other coaxial cable 104, 106, 108. This direct contact 302 allows two or more of the coaxial cables 104, 106, 108 to be grounded to each other. Therefore, by positioning the drain wire 114 within the outer jacket 102 such that the drain wire 114 is in direct contact 304 with at least one coaxial cable 104, 106, 108, the drain wire 114 may act as a common ground for one or more of the coaxial cables 104, 106, 108 when connected to a ground location such as a ball, pad, or other location used as an electrical ground. The drain wire 114 may be coextensive with the coaxial cables 104, 106, 108 along the entire length of the cable assembly 100.
