Deep Dive into ERP/EIRP Calculations
Introduction
This guide explains how to calculate Effective Radiated Power (ERP) and Effective Isotropic Radiated Power (EIRP).
What are ERP and EIRP?
ERP (Effective Radiated Power):
The amount of power that an antenna radiates, taking into account the antenna gain and cable loss.EIRP (Effective Isotropic Radiated Power):
The amount of power that an antenna would radiate if it were an isotropic antenna (an antenna that radiates power equally in all directions).
