Relation between dBd and dBi. The dBd value is compared with a dipole antenna, which itself has 2.14 dB gain over isotropic radiator. With this logic, antenna having gain of 7dBd will have gain of 9.14 in units of dBi. In other words both 7dBd and 9.14dBi with respect to antenna gain are equivalent. Following formula mentions relation between dBd and dBi. 0 dBd = 2.14 dBi Hence to convert dBd to dBi, just Add 2.14 To convert from dBi to dBd, â€¦
