Homebrew booster for Wireless

For those who go wireless at home and have a low signal, I found a site for a homebrew antenna booster that does work. It is called a "Cantenna". It is simple, however, I am using my Belkin wireless G, not the homemade antenna which you can also make. Get a large 2 pound coffee can, 6 inches in diameter. Make an opening about an inch from the bottom to run you wire and set your antenna inside. This makes it a "directional" antenna and you can zero in on the signal. I boosted from a "very low" signal to maximum "excellent" signal. Gotta love the free connection, from whoever I am leaching off of. Lucky me, I have 3 different connections to choose from. Hope this helps someone:) I will post a pic if requested.
