The first null may appear at an angle off the boresight similar to the 3 db full beamwidth.
The parabolic reflector antenna gain is calculated as the gain over an isotropic source i e.
Beasley and gary m.
This is a theoretical source that is used as the benchmark against which most antennas are compared.
Eirp or effective isotropically radiated power or equivalent isotropically radiated power is a measurement of output power in one direction from an ideal one dimensional source the ideal point source radiates electromagnetic energy in a spherical pattern so the maximum radiated power should be the same in all directions.
The advanced beam forming enables efficient interference reduction toward the terrestrial fs systems by setting nulls at those directions 59.
