[edit]Origin of the name



Cantenna dummy load suitable up to 30 MHz and up to 1 kW
The term 'Cantenna' originally referred to a product sold by Heathkit Co. in Benton Harbor, MI, USA. It was a 50-ohm resistive load used by radio amateurs.[1] However, in the more casual vernacular of the Do-It-Yourself community, it has functionally become a portmanteau of can (e.g. an empty Pringles can, see below) and antenna, since they're used to broadcast (and receive) signals, and not just terminate them.
[edit]Construction

Although some designs are based on a Pringles potato chip can, in reality this tube is too narrow to be practical.[2], however a cantenna can be made from various cans or tubes of an appropriate diameter.[3] Some designs include a pole mount to elevate the cantenna.[4]
[edit]Usage

While cantennas are useful for extending a wireless local area network (WLAN), the tiny design makes them ideal for mobile applications such as wardriving. The design of the cantenna is so simple that it is often the first antenna WiFi experimenters learn to build. Cantennas can even be used to increase cell phone range,[5] improve reception and decrease noise.
