dBi
Decibels relative to an isotropic antenna gain
dBi (Decibel)
A unit which expresses the ratio of two voltages, currents, or powers. It is used to specify
transmission loss, gain, or relative level. It is equal to 20 times the common logarithm of the ratio
of two voltages or two currents, or 10 times the common logarithm of the ratio of two powers.
