What is dB Gain?

In layman's terms, a gain value represents the relative level of signal enhancement a booster and/or antenna is capable of providing. A booster with a higher gain value will provide a stronger signal and/or a coverage area than one with a lower gain value.

Technically, gain is the ratio of a booster's or antenna's output power relative to the input power. Gain is usually expresed in decibels, abbreviated as dBs.
