EIRP Calculator
EIRP (Effective Isotropic Radiated Power) is the measured radiated power of an antenna in a specific direction. It is also called Equivalent Isotropic Radiated Power. It is the output power when a signal is concentrated into a smaller area by the Antenna. The EIRP can take into account the losses in transmission line, connectors and includes the gain of the antenna. It is represented in dB.
Enter the transmitted power, cable loss and antenna gain to calculate the EIRP (Effective Isotropic Radiated Power).

An ideal isotropic radiator/antenna is used as the reference point. It emits power equally in all directions. If the antenna has a gain, this power gets concentrated in a particular direction. This is known as EIRP. The EIRP allows comparisons between different emitters regardless of type, size or form. If you know the EIRP and the gain of the real atenna, it is possible to calculate the real power and field strength. The calculator above calculates EIRP based on the Power, Gain and Losses that you enter.
