[HamWAN PSDR] 5.8 GHz patch antenna info?

I'm in need of some gain antennas for my (HamWAN inspired) High speed 5.8 GHz backbone experiment. While I'm sure there's one in my future; the 30 db, $100 BBQ dish recommended is too big, too much gain and too many dollars. So - that brought me to the 20 dBi, $50 panels at Fab-Corp: http://www.fab-corp.com/home.php?cat=270 Potential candidates are the Echo Series 5.8 http://www.fab-corp.com/product.php?productid=2868&cat=270&page=1 And the tri-band patch: http://www.fab-corp.com/product.php?productid=3164&cat=270&page=1 Any known strong pro's or con's on either of these. Maybe one of each for experimenting? These will be driven with the 5SHPn or Grooves so the matching N connector is a requirement Thanks, Bill, WA7NWP
