I am sorry for the delayed, ever so delayed, reply to this matter.
http://www.innovativedevice.com/asp/InformationYagi.asp is an outfit which sells directly and also uses Ebay as a method for sales. This antenna addresses the very issue you're noting: It uses a USB connection; not "N". (It bypasses your laptops built in WiFi and utilizes it's own card which is built into the antenna permitting the use of the USB connection). Too, it is available as one piece or can be broken down into three pieces for ease of transport. This is an entry level antenna, but performs remarkably well. I have set up several of these throughout Costa Rica such that the "mother ship" is one guy's house who is getting a microwave feed at something like $75.00 per month. He ports the signal to a router which in turn is antenna equipped (transmitting if you will) and the rest of the neighborhood has high speed internet using the same antenna, working off his WiFi router. It's line of sight so those to the side of the yagi and behind it and have any distance from the router ain't in such good luck. (We're not trying to provide the "service" to every mother and her sons....). However, with multiple routers pointing in different directions....well...lots of things are possible.....). In one section which is MOST UNOBSTRUCTED we have successfully been able to sustain a very fat pipe (4megs down; 1.4 megs up) at distances exceeding almost 9km. Shhh.....don't tell the microwave distributor.....
For downtown San Jose, I've found many, many unsecured networks. However, I have not needed to use them. Hotel La Amistad has a consistently strong signal and is wired which is the way I like it. It also has wireless.....but I, again, prefer my CAT 5 cable. (Strength varies somewhat because the hotel is not using commercial quality routers and they don't reset/reboot the one's they have; I think they only get reset when there's a power outage!

). I have had speeds exceeding 3megs down while at Amistad using
http://www.speakeasy.net/speedtest/ and the Dallas, TX server as a testing source. (If you use
http://www.speedtest.net and the server in San Jose....boy howdy! You'll be thrilled. However, I think the test is full on incorrect. It is not measuring throughput.) However, it's not always that strong....but it has never been less than 1.6 down.... I really don't like sharing that data, either. Naturally, the more using the thing at the hotel, the greater the deterioration, particularly given the router set up.
Other antennas, working off a parabolic design are in use "up country". I won't bore the readership with the incredibly fine results being produced. Shhhh.....again.....don't tell the microwave distributor.....
Hope this isn't too late for you....

Steven,
I think the one you are talking about is the grid antenna on Ebay and other places on the internet. They all seem to come with an N connector. How do you connect that to a laptop? I'll talk to my IT guy on Tuesday. He may have some ideas as well.
Thanks.
