It certainly looks well-constructed, but I'd have a lot more confidence in
Cantenna's products if they had measured (or even simulated) radiation
patterns and calculations. They also don't mention their feed arrangement
which could make a huge difference in actual performance.

A home made yagi might fill the bill. Try one of these

There are many others. I had some success with one.

For a few dollars more, you can get real commercial antennas. My
internet service comes to me via a 7 mile hop using a PCI card or
WGB external box running 100mw. Works great, giving me better than
1/3 T-1 connection. When I swing the antenna around, I see all of
my ISP's APs, including one 35 miles away in the next state. I've
got a few links if you need them. I just went through them and see
that some have changed, but there's lots of stuff out there for
WiFi. Your main worry is the antenna connector, if you are running
a PCMCIA card.

Where does one get the external 100mw tranmitter? I am also looking for a
good omnidirectional radiator.

I have a linksys Wireless G router

Chip

They do show minimal specs, not a isotropic map like you may be used to

for ham antenna adds but 12db, 30 degree angle of radiation Its fed with
type N-male

connector. up to 50 watts input power 1:5.1 avg SWR @2.5 Ghz

choice of feedline of course would be up to you but I wanted to get the

thing up and running so for test purposes I used 20 feet of old RG-58

30 mw input and have it pointed at my ISP 4.5 miles away that's how I

get 1.5 Mb internet service
