How does antenna gain in dBi compare to gain stated in dBd for the same antenna?
Gain in dBi is 2.15 dB lower
Gain in dBi is 2.15 dB higher✓پاسخ درست
Gain in dBd is 1.25 dBd lower
Gain in dBd is 1.25 dBd higher
توضیح
dBd is referenced to a half-wave dipole, which itself has 2.15 dB of gain over an isotropic radiator, so the same antenna's gain figure is 2.15 dB larger when expressed in dBi.
