Co-Axial Cables

Co-Axial Cables

Coaxial cables are superior to most other radio/signal transmission lines is that it protects against external interference and electromagnetic fields. An ideal coaxial cable contains its own signal carrying electromagnetic field within the space between the two conductors, thus allowing for installation near metal objects (like ducts and gutters) without the power losses that occur in other kinds of transmission lines.

Furthermore, coaxial cables are used to carry low frequency signals, such as audio signals, where the dimensions of the cable are controlled to give a precise, consistent conductor spacing, which is required for the cable to function efficiently as a radio transmission line or for medical purposes like patient monitoring, ECG etc.
