The difference between erp and eirp is that antenna gain has traditionally been. The effective radiated power erp or eirp is the gain of an antenna with respect to an isotropic radiator multiplied by its input power. Total radiated power trp is a measure of how much power is radiated by an antenna when the antenna is connected to an actual radio or transmitter. The total received power is calculated and summed up over all possible angles hence, it is a spherical or 3d measurement and the result is the.
