True Diversity

A wireless microphone term. A more advanced form of a diversity receiver, a true diversity system contains a radio receiver that actually has two independent receiver sections, each with its own antenna (rather than a single receiver with one or two antennas), to pick up the transmission from a wireless microphone. The antennas are spaced apart on the unit, and by means of a comparison circuit the unit constantly polls the two receivers to select the one with the strongest signal. The result is an exceptionally stable signal, since the appearance of a dropout in both antennas at the same time is not likely under normal circumstances.
