Yeah, but don't forget a cylindrical antenna like a Pringle's can is a directional shotgun antenna, and requires the client to be an unmoving target.

Hmm. Maybe i could set up some robotics and a GPS to take care of the moving client problem...

Did you have any specific questions about WiFi or home made antennas?

I'm thinking about wireless-lanning a couple of houses. I think there is a direct line of site between my house and his from the roof. Its maybe a quarter mile distance. Probably breaks an FCC regulation or two eh? :angel:

Actually WiFi antenna mods are FCC legal because you're not increasing total transmission power, you're only changing the transmission dispersal pattern into a directional antenna.

However, under FCC class B you have to turn off your rig if the neighbors complain their 2.4 GHz phones or their WiFi stop working.

Schweet :) I guess stealing internet access from the nearby highschool would be ruled out though :D

I checked this out when my router was being all ****ty on me--apparently, there's a design using a certain spaghetti can that works quite a bit better. I'll try to find it for you in a bit.
