Extend WiFi range with homemade Tin Can Antenna Mod

"Got no dough for a commercial WiFi 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 built for under $5 U.S. and reuses a food, juice, or other tin can.", says Gregory Rehm who hacked up this Wifi range extender.

Lovely, we must say. Check out the plans on how to make this cantenna here.
