The food can came up to almost perfect dimensions, though the edges lringles ridged, which will impact its performance. They can also be very useful to people who rely on public internet access. One of the first things that got me excited was the Pringles Can Antenna. The various community wireless network groups all talk about them and folks are reporting that they do the job.

In the yagis, it didn’t matter much. I used a free piece of software called Homedale to measure the strength of the Wi-Fi signals I was receiving, in both cases you can see the cantennas blue line going off the top of the graph gave a peingles higher signal when compared with the internal Wi-Fi receiver of the laptop yellow line.

Now I’m a late entry into this wireless stuff and the experts are going a different way than me. Cantennas are typically used to increase the range or discovery of Wi-Fi networks.

Of the waveguides, the Nalley’s “Big Chunk” took top marks. By using this site, you agree to the Terms of Use and Privacy Policy.

If this seems like something a little out of scope, another incredibly simple way to boost your Wi-Fi aifi is to create a parabolic reflector to place behind it and focus the signal.


This could be because neither Rob’s nor my designs are anywhere near right for optimum performance for a Yagi. You can use this tool to calculate whether the cans you have collected would be effective. A great tool for drilling holes in thin sheet metal is a “stepped” drill bit “Unibit” or clone thereof.

Cantennas are typically used for extending a wireless local area network WLAN.

The pringlex is the small piece of copper wire which will stick out into the middle of our can. For Heathkit Cantenna antenna-related device, see Dummy load.

Clocking it at an inside diameter of 72mm, a the Pringles can is too thin. Just to test I also made one using only a screwdriver to punch a hole, and a pair of needle nosed pliers to slowly bend it outwards until it was the correct diameter.

The coffee can was a little short on length, but the 2cm it is lacking is still quite the difference from the 26cm of length the Pringles can falls short on. Attach the other end of the pigtail to the protruding N type connector. Wireless networking Radio frequency antenna types Antennas radio. Also, there are conflicting opinions as to whether the Yagi collector design is any more effective than a well proportioned waveguide design. To see if I could improve upon the design, I built mine with corrected spacing.

My three waveguide designs, which utilized the correct theoretical spacing, out performed the Flickenger Yuban coffee can handily. Let us know in the comment section below! In our test, the Flickenger Pringles can did a little better than my modified Pringles design. Scroll down for the next article.

While folks are calling it a Yagi-Uda style antenna, the design of the driven element in the Pringles can antenna looks like a Waveguide style design. I didn’t compare them to a commercial directional antenna as my only one has a male connector and I don’t have the right cable to hook it up yet. Have you come up with your own crazy designs for boosting your Wi-Fi signals? Now that we have our probe and N connector together, we need to mount them in the right place on the can. Cantennas may be used with other RF devices such as wireless security cameras.
