The cantenna has a long history of fanfare dating back to approximately 2002 when Andrew Clapp created the first Pringles cantenna. Shortly afterwards Rob Frickenger, a community wireless advocate, improved upon Andrew Clapp’s yagi designed Pringles cantenna and created the first true waveguide directional cantenna using a 36oz coffee can. Since then, the cantenna design has been adopted by wardrivers, DIY hackers, community wireless advocates and hobbyists from all over the world. The cantenna has even received interest from the United Nations IT Consortium and various humanitarian non-profits who are interested in using its inexpensive and easy to build design to deploy wireless networks in developing countries such as Africa and the Middle East.
Below are some examples of various cantenna designs created by hobbyist and wireless network groups the world over.
