Front to back ratio is the measure of directivity of a directional antenna: A ratio of the energy directed in a single direction, which is dependent on the radiation pattern to the energy wasted in or by the antenna. Increase the gain of a directional antenna, is the same as increasing the front to back ratio. The best front to back ratio of a directional antenna is a large dish antenna: 34dB.
