WebThe half-power points of the antenna radiation pattern (i.e. the −3 dB beamwidth) are normally specified as the limits of the antenna beamwidth for the purpose of defining angular resolution; two identical targets at the same distance are, therefore, resolved in angle if they are separated by more than the antenna −3 dB beamwidth. WebThe default value is 3 dB, which translates to half-power beamwidth. To calculate first-null beamwidth, specify the 'dBDown' value as Inf.
