A diversity antenna system can be compared to a switch that selects
one
>antenna or another, never both at the same time. The radio in receive
mode
>will continually switch between antennas listening for a valid radio
>packet. After the beginning sync of a valid packet is heard, the radio
will
>evaluate the sync signal of the packet, on one antenna, then switch to
the
>other antenna and evaluate. Then the radio will select the best
antenna,
>and use only that antenna for the remaining portion of that packet.
>
>On transmit, the radio will select the same antenna it used the last
time
>it communicated to that given radio. If a packet fails, it will switch
to
>the other antenna and retry the packet.
