How close is "close to an Air Force base"? I've always been kinda curious as to just how big the scope of the DFS stuff is. I'm about fifty miles from one, and while I'm not presently using any gear that would require DFS, I can't help but wonder how much (if any) impact there would be if ever I did move into those middle bands. Anyway, if you're in the 5.8GHz range, you should be okay. DFS is required for the "lower" stuff: 5150-5350 and 5470-5725. The unlicensed 5.8GHz band should be exempt from this.
