The cylinder portion of the can may consist of metal-coated paperboard. For Heathkit Cantenna antenna-related device, see Dummy load. The tiny design makes them ideal for mobile applications such as wardriving.

Even a millimeter off here and your Cantenna may not prinvles as well as it could!

qntena I even went so far as going grocery shopping with a tape measure. While waiting for some wireless equipment to come in, I started looking for my next antenna project. To do this, I setup a wireless link and changed only the antenna- recording each antennas’ performance under identical conditions. The 13 Best Raspberry Pi Projects of A great tool for drilling holes in thin sheet metal is a “stepped” drill bit “Unibit” or clone thereof.

It’s the easiest antenna design I know of. 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.

I tested both the coffee and food can designs, and both boosted my Wi-Fi significantly. By using this site, you agree to the Terms of Use and Privacy Policy. Now that the can itself is finished, we need a way to attach it to our computer or router to reap the benefits.

Clocking it at an inside diameter of 72mm, a the Pringles can is too thin. This method is a little involved, and may vary from router to router.

Measure carefully to the length specified in your calculations, and cut the probe to the correct length. I used a drill followed by an angle grinder on my rotary tool — which was fiddly to say the least!

Archived from the original on It’s time to benchmark. While the coffee can cantenna is still not optimally sized, it performs well as a performance booster, and wufi the food can performing well in close quarters too, I am looking forward to testing these over a greater range.

It’s about three quarters of a wavelength in diameter, hon!

The closer you get to the dimensions from the calculator, the better your cantenna will function. The resulting setup is a low-cost high-quality high-gain antenna. One of the first things that got me excited was the Pringles Can Antenna.

How To Make a Wi-Fi Antenna Out Of a Pringles Can

Another approach to take is to connect the cantenna to your router to boost the signal from the source. Many people pringle them to extend their Wi-Fi signal to a hard to reach part of the home, or even extend their Wi-Fi to the bottom of the garden.


In many situations this will be the difference between intermittent, close to unusable internet and a stable usable connection.

You should now be able to fit the connector, by pushing it through and attaching the nut from the inside. The first decision to make is which kind of can to use.

antenna It is worth doing this regardless however, as you can expect to see great performance increases from this upgrade alone. A cantenna can be used as a satellite dish feed horn. 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 anttena see the cantennas blue line going off the top of the graph gave a significantly higher signal when compared with the internal Wi-Fi receiver of the laptop yellow line.

The waveguides all soundly trounced the Pringles can designs. I found that a coffee can diameter 88mmand a large food can mmwere closest to the right size.
