Can Antanna

Pringles vs. cantenna

Now that we've given you fair warning, here's a heads up. Pringles antennas are a pain to build and require more time than cantennas. Cantennas get significantly better gain, too.

Pringles antennas need lots of parts and fabrication.

  • The can
  • Wire
  • Washers
  • Nuts
  • Threaded rod
  • Tubing
  • Plastic
  • N-connector
Get the details for building a Pringles can antenna. (Props to O'Reilly's Rob Flickenger for this excellent how-to.)

A cantenna needs the following.

  • A can
  • N-connector
  • A little over an inch of copper wire
  • Nuts and bolts
Plus, Yuban coffee tastes better than Pringles. For an even more effective cantenna design, look at this project, which lets you tune it to whatever size can you've got available. Very cool, Greg! Take a look at his Homebrew Antenna Shootout, too!
