Patent ID: 7595647

Claim:
A cable assembly, comprising: a cable comprising: a first coaxial cable; a second coaxial cable; an internal cable; and an outer sheath surrounding the first coaxial cable, the second coaxial cable and the internal cable; and a loop assembly comprising: an energizing loop connected to the first coaxial cable for transmitting an energizing signal via the first coaxial cable and the energizing loop; and a sensor coupling loop connected to the second coaxial cable for receiving a sensor signal via the second coaxial cable and the sensor coupling loop; wherein to maximize isolation between the energizing signal and the sensor signal, the first coaxial cable and the second coaxial cable are positioned on opposite sides of the internal cable such that the first coaxial cable is in contact with one side of the internal cable and the second coaxial cable is in contact with an opposite side of the internal cable, and a position of the first coaxial cable relative to the second coaxial cable is maintained along a length of the cable.
