That is a good idea, however it is not really characteristic of diversity.
In an environment where your already limited in Tx power it seems silly to
induce even a few  dB of loss on the receive by having another diversity
switch in the receive path. I may be wrong, it may make little difference, I
suppose intersil should know what they are doing :)

On a further side note, are the Prism range of chipsets limited to 15dBm? or
are there 200mW versions? In Australia, the max EIRP for the 2.4GHz band is
4W, however no one seems to sell any 200mW models. It would be nice to take
advantage of a higher output card with out the need for overly high gain
antennas.
