n. A transmission line, consisting of a conducting wire surrounded by an insulated spacer, surrounded by a cylindrical conducting sheath; used to carry high frequency signals such as TV.
RG-59 flexible coaxial cable composed of:
- Outer plastic sheath
- Woven copper shield
- Inner dielectric insulator
- Copper core
Coaxial cable, or coax (pronounced ), is a type of cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. The term coaxial comes from the inner conductor and the outer shield sharing a geometric axis. Coaxial cable was invented by English engineer and mathematician Oliver Heaviside, who patented the design in 1880. Coaxial cable differs from other shielded cable used for carrying lower-frequency signals, in that the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a transmission line.
Usage examples of "coaxial cable".
Copper-based coaxial cable systems are still in operation in many places around the world, but all of them will have reached the end of their practical lifetimes within a few years.
Kleveland and his movie camera, Tommy and Gerlock flapped off along the beach to the point where the RUM's coaxial cable entered the surf.
A coaxial cable extending from the back of the antenna was plugged into Higgins's HST-4 unit.
He saw no sign of coaxial cable threading down the rocky slope below.
The phalanx of machinery at the end of the coaxial cable had reached the South Pole of the binary.
He saw the radio ham remove the dummy antenna--a 500-watt light bulb--and attach the coaxial cable which led to the vertical antenna outside the trailer.
And when he approves the tape then it's put over the coaxial cable and transmitted to all the ant tanks in Wes-Dem.
He screwed the antenna's black, coaxial cable into the radio, slipped on his headset, and listened as the system went through a self-calibration check.
I sat there, feeling like a spider at the center of an endless web reaching out over a worldby coaxial cable or relay towers or some version of miracle we don't use ourselvesand spying on every dweller here.

The probe looked like an aluminum pipe but was really a special tube built like a segment of coaxial cable.
