What Is Antenna Gain?

- Jul 24, 2018-

Antenna gain is also known as antenna directivity. It refers to the signal ratio between the directional antenna and the non-directional antenna. This ratio can be used to measure the effectiveness of a directional antenna relative to a standard non-directional antenna in dB, with the measured value along the antenna being positive and the reverse antenna being negative. This ratio has the same reference value when reflecting and receiving signals.
