EIRP (Effective Isotropic Radiated Power)

Effective Isotropic Radiated Power (EIRP) is a measure of the power a broadcast antenna emits, accounting for both the output power and how effectively the antenna directs that power in a specific direction. It combines the actual power fed into the antenna with its gain, which describes how much it concentrates the signal compared to an ideal, uniform antenna. EIRP is expressed in watts or decibels and helps determine how far signals can travel, making it essential for telecommunications, broadcasting, and satellite communication to ensure reliable connections and coverage.
