Notebok Review took a look at this super Wi-Fi antenna, giving a wireless range of more than 1.2 miles!

"I recently was given the opportunity to test the Super Cantenna Wireless Booster Antenna. The Cantenna name is appropriate given that the product is in the shape of the can, similar to a Pringle's can in size, and sits on a tripod. The seemingly simple design is advertised to stand apart from the homemade "Pringle's" type antennas due to its dimensions, shielding, and polarization, which have been engineered for maximum signal strength and distance. The product is advertised to extend the range of your wireless network, bridge gaps in your wireless network, or connect to other networks in the neighborhood."
