How does antenna gain in dBi compare to gain stated in dBd for the same antenna?
Pick an answer to check it.
Answer: B. Gain in dBi is 2.15 dB higher
dBd compares to a dipole, while dBi compares to an isotropic radiator. A dipole has 2.15 dBi of gain, so gain in dBi is 2.15 dB higher than the same gain in dBd.
Tip: dBi = dBd + 2.15.
