I have a theoretical question about EIRP.
EIRP is calculated by summing the power of the radio (the intentional radiator, IR) plus the gain of the antenna (dBd/dBi) minus the sum of the losses. The calculated value is equivalent to the power which a isotropic radiator would need to provide the same power density as the original antenna in the direction of maximum gain.
Is this statement true:
"Since antennas are passive elements it would not be possible to measure more power on any given theoretical client than the power (Watts (Energy/Time)) provided by the I.R. The gain of the antenna increases the power intensity, applying the same amount of power to a smaller area but does not change the total radiated power."
