A cantennaantenna, canteen, antennae, canteens, Canton, canton, Janenna, canting, continua, canteen's, cantonal, cantons, contemn, Catina, canter, canted, Canton's, cantering, canton's, Canadian, contend, content is a very simple but effective antenna, used for 802.11b
wireless networks or other 2.4GHz applications. It is basically a tin
food can with a N-connector (with a piece of wire) at the right
position in the can's side.

See How To Build A Tin Can Waveguide Antenna [2].

In order to improve the reception of the cantenna, bouncing it off a
parabolic reflector is a great improvement. One of the best Melbourne

Mark Vincent followed the directions and specifications on Grant's
website and tested them at InstallfestInstall fest, Install-fest, Installers, Installment, Installed, Installs, Unstablest, Installer's, Instalment, Unsafest 2002. At 24dBi gain, it rates
very well against the commercial alternatives. (see photos [4])
Remember: the distance from the base of the can to the N-connector
wire is 6.2cm according to Grant, confirmed at Installfest. NOT 3.1cm

"Got no dough for a commercial antenna? Looking for an inexpensive
way to increase the range of your wireless network? A tin can
waveguide antenna, or Cantenna, may be just the ticket. This design
can be build for under AUD$5 and reuses a food, juice, or other tin
can".
