ABSTRACT:
A thin flat twisted-pair gap cable and gap navigator unit reduces the diameter of twisted-pair wire, aligns them side by side, and fuses and fixes them in place with two plies of tape so as to flatten the conventional round twisted-pair cable in order to pass the conventional round twisted-pair cable used for high-speed transmission through a gap in a window sash or the like. Two core wires each consisting of a small-diameter conductor covered with an insulating covering of PE or the like are twisted together evenly to make the twisted-pair wires, with the necessary number of twisted-pair wires aligned side by side. The insides of two plies of plastic tape are coated with a thermoplastic adhesive and the aforementioned cable is inserted into and sandwiched between the two plies of plastic tape and the tape fused together so that the twisted-pair wires aligned side by side come in the middle of the width of the tape to form a flattened gap cable. Adhesive tape, with the adhesive surface facing out is provided on one side of this flat cable to enable the cable to be stuck to the surface of the gap in the sash of the window.
