ERP/EIRP online calculator

App Description

Input data: actual transmit power of the transmitter; antenna gain

Output data: Effective Radiated Power (ERP); retains three significant digits; equivalent isotropic radiated power
(EIRP); retains three significant digits

Formula: \(EIRP=Pt \times Gt\)

Usage example

Transmitter actual transmit power = 5; antenna gain = 5

ERP=11.990; EIRP=14.138

Note

ERP refers to the effective radiated power; EIRP refers to the equivalent isotropic radiated power
