Effective radiated power
…significant losses L , the power applied to the antenna is usually less than the output power of the transmitter P T X . The relation of ERP and EIRP to transmitter output power is E I R P ( d B W ) = P T X ( d B W ) − L ( d B ) + G ( d B i ) , E R P ( d B W ) = P T X ( d B W ) − L ( d B ) + G ( d B i ) − 2.15 d B .
