Wi-Fi is a fantastic new gadget, but its reach is only about 50 to 100 meters. Fortunately it is possible to build the authors' own antenna cheaply (less than 10 US dollars) in an hour or two. Now a day, more individuals, businesses and local governments are enjoying wireless internet access proliferating Wi-Fi hotspots, home, office, and public wireless networks. However, Wi-Fi users are rarely completely satisfied with the signal strength offered by the off the shelf Wi-Fi cards, routers, access points and USB adapters. Compounding to the coverage problems, many locate their routers, access points or desktop Wi-Fi cards in a closet, against the wall or under a desk, diminishing signal strength and limiting bandwidth.
