Terms starting with ‘C’
C
- Cable Loss
- A numeric value describing the amount of signal loss from one point on a length of cable to another. This is measured in decibels (dB).
- Cassegrain Antenna
- A parabolic antenna in which the feed radiator is mounted at or behind the surface of the concave main parabolic reflector dish and is aimed at a smaller convex secondary reflector suspended in front of the primary reflector. The beam of radio waves…
- Co-Polarization
- That polarization which the antenna is intended to radiate.
- Coaxial Cable
- A type of cable which contains two conductors, one inside and the other outside around it, separated by an insulating layer. They share the same axis and are concentric. Coaxial cable "co-ax" is commonly used in cable-TV and Ham radio…
- Coaxial Dipole Antenna
- An antenna comprised of a extension to the inner conductor of a coaxial line and a radiating sleeve which in effect is formed by folding back the outer conductor of the coaxial line.
- Collinear Antenna Array
- An array of dipole antennas mounted in such a manner that the corresponding elements of each antenna are parallel and collinear, that is they are located along a common line or axis. A collinear array is usually mounted vertically, in order to…
- Collinear Array Antenna
- A linear array of radiating elements, usually dipoles, with their axes lying in a straight line. Collinear arrays are usually found in omnidirectional antennas.
- Corner Reflector
- A retroreflector consisting of three mutually perpendicular, intersecting flat surfaces, which reflects waves back directly towards the source, but shifted (translated). The three intersecting surfaces often have square shapes. Radar corner…
- Counterpoise
- A type of electrical ground that is not connected to earth. It is used in radio antenna systems when a normal earth ground cannot be used because of high soil resistance. It consists of a network of wires or cables (or a metal screen) running…
- CPE Antenna
- Customer premises antenna, usually a small directional antenna which points to an access point.
- Cross-Polarization
- In a specified plane containing the reference polarization ellipse, the polarization orthogonal to a specified reference polarization. The reference polarization is usually the co-polarization.
