All practical antennas have some directivity -- putting out more power in some directions than others. Ideally, you would like to put power out (and receive from) only in the direction toward the station you're talking to. A "beam" antenna, designed for directivity, can increase your signal by 1 S-unit (6 dB) or more, receiving and transmitting.
