EIRP definition: (Equivalent [or] Effective Isotropically Radiated Power) A measurement of the amount of power emitted by an antenna. In a locality, the EIRP of antennas are taken into account in order to avoid interference on the same frequenc...
ERP,EIRP,dB and dBm definition in RF Planning. 1  Has a power gain of unity i.e. 0dBi. 2  The radiated power from a half-wave dipole. 3  A lossless half-wave dipole antenna has a power gain of 0dBd or 2.15dBi.
