A typical diversity receiver consists of two receiver modules and a RSSI switch which monitors signal strenght from the receivers and selects to stronger one for the a/v output. In my case, for example, both a/v receivers are tuned to the same chanel (5645 GHz) but their antennas are different. There is an omni-directional antenna attached to the other reveiver and a directional antenna to the other. That means, I can fly relatively far away (~300m) to one direction and still fly around my base station (~150m).
