Low loss buoyant coaxial cable

A low loss buoyant coaxial cable has its buoyant material placed between conductors to allow for maximum cable cross section for electrical transmission. In addition the strength members are placed radially inward of the center conductor to reduce wearing of the strength members and keeping the electrical performance independent of the electrical properties of the strength members. An alternate embodiment has buoyant material centrally located and the strength members placed with buoyant material between the coaxial conductors.

DETAILED DESCRIPTION The low loss buoyant coaxial cable provides a great improvement in attenuation over previously employed buoyant coaxial cables thereby permitting the transfer of higher frequency radio signals and/or utilization of greater lengths of cable.
The improvement in attenuation is achieved through better design and arrangement of the functional components of the cable.
Maximum utilization is made of the cable cross section for electrical transmission.
This is achieved by placing the buoyant material between the coaxial conductors.
In one embodiment, the strength members are placed within the center conductor thereby reducing wearing of the strength members and keeping the electrical performance independent of the electrical properties of the strength members.
