Over the weekend I tried some range testing with the xbees with a pair of 2dBi duck antennas. I only got about a half mile away from my car, in the open, before they started having trouble communicating with each other. Unfortunately this range will not do. I'd like to be able to get at least a mile or two out of them. Now to figure out how to optimize this. There aren't any cement buildings at burning man, but lots of camps, RVs and wooden structures. If you have any ideas, let me know.
