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. I found that making a slightly too small hole which I then widened using a file worked well. To do this, I setup a wireless link and changed only the antenna- recording each antennas’ performance under identical conditions. While there are many variations on this prongles of build, today we are striving for a balance of price and simplicity. They can also be very useful to people who rely on public pringlss access.

It’s time to benchmark. I decided to make both cans into cantennas — this guide covers the construction of the coffee can, though the construction is exactly the same for both, just with different spacing as per the calculating tool above. Once that is done, remove pringlws aerial that comes with the adapter by unscrewing it, and attach the smaller end of your pigtail connector instead. 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.

A great tool for drilling holes in thin sheet metal is a “stepped” drill bit “Unibit” or clone thereof. Both did no better than the Lucent omnidirectional. This page was last edited on 13 Mayat You could even use it to share your connection with a nearby house if you are feeling neighborly!


Another approach to take is to connect the cantenna to your router to boost the signal from the source. Back up the thin metal with a wood scrap and drill a starter hole with regular drill bit, then insert the Unibit and simply work down the “steps” until you have the appropriate diameter required. For information about reproducing this article in any format, contact prnigles author: Whichever method you use, measure the diameter of your N type connector with the nut removed, and make a hole slightly bigger, so that the N connector can slide in.

The Shootout My plan was to get relative performance measurements for various designs including mine of homebrew antennas for It’s about three quarters of a wavelength in diameter, hon! With these results, I’m convinced that the waveguide design is the way to go for cheap wireless networking.

The first decision to make is which kind of can to use. Now this is just on raw signal strength, noise rejection due to pringlss still makes a directional antenna a better choice for some uses even if there is no gain benefit. The resulting setup is a low-cost high-quality high-gain antenna. Why would you want to make something like this?

I used a drill followed by an angle grinder on my rotary tool — which was fiddly to say the least! Wireless networking Radio frequency antenna types Antennas radio.

Perfect for when your own internet goes out and you want to wntena able to keep surfing in your slippers! Published on the internet and in a fine book by Rob Flickengerthe net admin for O’Reillythis design for a do-it-yourself, VERY inexpensive antenna made from a recycled junkfood container is as cool as the other side of the pillow.

I managed to cut my hand twice on the inside rim of the coffee can. The important part to pay attention to once you have the calculations for your diameter is the inside length. Many people connect their cantennas to tripods in order to get the best control over direction and orientation, in this case a little Macgyvering with zip ties and an old plastic plant pot did the job perfectly!


By pointing a transmitting cantenna from your router to a receiving cantenna at your computer, you will be able to boost your range significantly. Cantennas may be used with other RF devices such as wireless security cameras.

Pringles Can Antenna Turns 10

Now that we have our probe and N connector together, we need to mount them in the right place on the wntena. The signal strength improvement is 20 dB, not 20 dBm. In the yagis, it didn’t matter much. In our test, the Flickenger Pringles can did a little better than my modified Pringles design. For the antennas I was building, I was using different measurements based on the antenna design material I had been reading.

I tested both the coffee and food can designs, and both boosted my Wi-Fi significantly. Gergory Rehm of Turnpoint. The 13 Best Raspberry Pi Projects of In many situations this will be the difference between antna, close to unusable internet and a stable usable connection. I’ve decided that Yagi design is not for the timid or non-radio-expert. Retrieved from ” https: The size of our choice is important, as there are set fundamental dimensions which allow the cantenna to work.

For the battle, see Battle of Aantena.

The cylinder portion of the can may consist of metal-coated paperboard. Where possible, a clear line of sight is best, though I found there to be a significant signal boost even pointing it through the thick walls of the old apartment building I live in.

Greg’s obsession de’ jour In my efforts to add the words “wireless savvy” to my network admin resume, I’ve been reading books and web pages on radio propagation, antenna theory and design, and building wireless networks with
