Abstract
A diversity receiving apparatus includes first and second antennas and circuitry for selecting one antenna or the other. Control circuitry analyzes signal strength received from the selected antenna and determines when the antennas should be switched. The antennas are switched when the received signal strength falls below a running average thereof; the received signal strength falls below a threshold value; or a predetermined time has elapsed since the antennas have been switched. The antennas are switched when the received signal strength falls below a running average thereof; the received signal strength falls below a threshold value; or a predetermined time has elapsed since the antennas have been switched.
