CANtenna

Go to www.fab-corp.com,

choose "802.11 Pigtails" from the bar on the left, and then search for

"Cantenna Kit, 19 inch ORiNOCO". There you've got all the connectivity

taken care of, and follow the link to Turn Point Wireless

(http://www.turnpoint.net/wireless/cantennahowto.html) to learn how to

make your antenna. It's even got a built-in calculator to calculate the

cutoff frequencies you'll get for a particular can size.

If you happen to have an old Primestar dish lying around,

http://www.wwc.edu/~frohro/Airport/Primestar/Primestar.html is a good

how-to for attaching the cantenna as the feed horn on these surplus dishes

and getting even better signal gain.
