Abstract: A method and system for selecting and reselecting an antenna direction for an antenna capable of transmitting signals in one of at least two selectable directions. The average received signal-to-interference ratio is used to initially select the antenna direction. Thereafter the average received signal-to-interference ratio is monitored and the antenna direction reselected when the average received signal-to-interference ratio rises too far below the average received signal-to-interference ratio used to initially select the antenna direction for too long too often and if the antenna is not then required for a transmission that cannot be interrupted. If the average received signal-to-interference ratio drops significantly below the level used to initially select the antenna direction, then that level is reset downward. Reselection, if commenced, is repeated periodically until the antenna is required for transmission of a signal.
