Definitions for "Omni-Directional Antenna"
An antenna having an essentially non-directional pattern in azimuth, and a directional pattern in elevation.
Antenna that radiates equal power in all directions in a horizontal plane.
An antenna that can pick up signals from all directions; i.e., it doesn't have to be pointed directly at the source of the signal to pick it up. Typically this type of antenna is used when the specific direction of the signal is not known, when one antenna is receiving and transmitting in several directions (as in a repeater station in an RF network), or for mobile applications.
