EIRP Calculator

A-INFO's EIRP Calculator determines the radiated power given the transmitter power, the cable loss to the antenna, and the gain of the antenna.

Effective Isotropic
Radiated Power:

EIRP, or effective isotropically radiated power, or equivalent isotropically radiated power, is a measurement of output power in one direction from an ideal, one dimensional source. The ideal point-source radiates electromagnetic energy in a spherical pattern, so the "maximum" radiated power should be the same in all directions.

**Note: All of our calculators allow SI prefix input. For example, if you wish to input "25000000", just type "25M" instead. See the quick-reference table below for all compatible SI prefixes.
