Is this the one you're referring to?  http://www.atmel.com/Images/zigbit_2.jpg

Does this particular design utilize the antenna diversity feature described 
starting on page 89 of the rfa1 datasheet?

If so, it's curious to me that the Zigbit design would have two antennas so 
close together, and use what I assume are identical chip antennas.  Would 
having identical antennas that close together--even in an antenna diversity 
setup--give that much better overall performance?
