Outer plastic sheath. B. Woven copper shield. C. Inner dielectric insulator. D. Copper core. Coax. Cable. Coaxial cable, or coax is a type of cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Coaxial cable differs from other shielded cable used for carrying lower-frequency signals, such as audio 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 radio frequency transmission line..

That portion, usually wires or rods, of a radio transmitter or receiver station used for radiating waves into or receiving them from space. It changes electrical currents into electromagnetic waves, and vice versa.. Joe Horanzy . AA3JH. April 4. th. , 2013 K3DN Presentation . Agenda. Awards. Impedance. Measuring Equipment.
