ABSTRACT:
This invention is a coaxial cable with watertight compartments between the discs that hold a center conductor coaxial with a tubular outer conductor. The object of the invention is to obtain greater mechanical strength for the cable without undue increase in attenuation. Discs are connected with the center conductor by a chromate conversion coating on the copper of the center conductor; by a polyethylene tube hugging the center conductor; and by necked down regions of the center conductor. This latter construction makes the cable suitable for microwave transmission as well as TV signals. Disc bonding to the outer conductor utilizes coatings on the inside surface of the outer conductor.
