A method of reception providing protection from signal loss due to multi-path nulls, which are localized small areas with a very low RF signal level caused by multi-path propagation.

A standard single-channel RF receiver.

The most common implementation of a true diversity receiver, in which the audio from the better of two receiver channels is continuously selected by means of an electronic switch.

A form of diversity that uses two spaced antennas and two receiver channels tuned to the same frequency. Essentially eliminates signal loss (dropouts) by instantaneously selecting the audio output from the receiver channel having the stronger RF input signal. Also referred to as space diversity or dual-receiver diversity.
