The Coaxial cable assembly or commonly called “coax” is a type of wire which conducts an electrical signal using an inner conductor commonly referred to as the Coaxial cable assembly center core. This is surrounded by a dielectric insulator covered with a metallic shield and all enclosed with an outer insulating jacket. The metallic shield is usually kept at a ground potential and a signal carrying voltage is applied to the center conductor. The wire is pretty flexible, strong and brings us satisfying results in audio, video or data applications.

The Coaxial cable assembly is applied as a transmission line for radio frequency signals and can be most commonly found attached to the TV’s antenna in port. The device which uses this type of wire as a transmission line usually has a certain characteristic impedance specified in ohms. Depending on the Coaxial cable assembly used, the wire’s impedance usually ranges from 50 up to 95 ohms.

One of the advantages that the Coaxial cable assembly has over other types of radio transmission line wires is that in an ideal Coaxial cable assembly the electromagnetic field carrying the signal exists only in the space between the inner and outer conductors allowing Coaxial cable assembly runs to be installed next to metal objects such as gutters without the power loss that occurs in other types of transmission line wires.
While all of this may sound very intriguing the coax wire design choices affect physical size, frequency performance, attenuation, power handling capabilities, flexibility, strength, and cost. Which leads us to have a variety of types of this wire to choose from which are built accordingly to the application and environment that the wire would be installed in.
