ABOUT CANTENNAS
A Cantenna is a do-it-yourself antenna used to increase the range of a wireless network connection. It is made up of a couple electronic components (copper wire and a connector) and a tin can. It can be hooked up to a wireless Internet router therefore making the wireless network accessible at a further distance. It can also be hooked up to the network card on a computer and used as a way to tap into a wider range of wireless networks that a computer’s wireless antenna would not otherwise be able to pick up.
Cantennas are very popular amongst
computer hobbyists. Amateur instructional videos and websites about how
to build Cantennas can be found all over the Internet. Despite its popularity,
the Cantenna has been outlawed in certain parts of the world as it is
seen as a device used by hackers to ‘hijack’ unprotected networks.
In Sacramento California it is illegal to have possession of a Cantenna.
