Editing Effective height

In [[telecommunications]], the '''effective height''' of an [[antenna (electronics)|antenna]] is the height of the antenna's center of [[radiation]] above the ground.

In low-[[frequency]] applications involving loaded or nonloaded vertical antennas, the effective height is the moment of the current distribution in the vertical section, divided by the input current. For an antenna with a symmetrical current distribution, the center of radiation is the center of the distribution. For an antenna with asymmetrical current distribution, the center of radiation is the center of current moments when viewed from points near the direction of maximum radiation.

In antenna theory, it is often used interchangeably with [[antenna effective length]], where it is defined as the ratio of the open circuit voltage across the antenna's terminals to the incident electric field of a radio signal.
