The various community wireless network groups all talk about them and folks are reporting that they do the job. For Heathkit Cantenna antenna-related device, see Dummy load. Once you have your precise anetna it is time to cut the hole. The first decision to make is which kind of can to use. The inner lining of a Pringles can looks metallic, but my tests show it not to be. The important part to pay attention to once you have the calculations for your diameter is the inside length.

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. The contestants were click on each for design specifications.

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. Oddly, the more I studied, the less I understood. For the battle, see Battle of Cantenna. The general consensus is that a can with an inside diameter pingles between 76mm and prringles work best, with 92mm being the sweet spot.

Why would you want to make something like this? Formulas in hand, I started searching my cupboards for tin cans that fit the spec. My three waveguide designs, which utilized the correct theoretical spacing, out wkfi the Flickenger Yuban coffee can handily. It is worth doing this regardless however, as you can expect to see great performance increases from this upgrade alone.

Cantenna – Wikipedia

Where possible, a clear line of sight is best, though I found there to pringgles a significant signal boost even pointing it through the thick walls of the old apartment building I live in. Measure carefully to the length specified in your calculations, and cut the probe to the correct length.

This article is about a microwave antenna. A more efficient cantenna can be made by minimising this length or connecting the cantenna directly to the Wi-Fi circuitry.

I mean they stomped them into the ground on signal strength – as much pribgles 9 dB better. You could even use it to share your connection with a nearby house if antsna are feeling neighborly! Let us know in the comment section below! In our test, the Flickenger Pringles can did a little better than my modified Pringles design. 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 closer you get to the dimensions from the calculator, the better your cantenna will function.

Have you built a Cantenna in the past? For information about reproducing this article in any format, contact the author: Firstly, you can try pringkes add one yourself. 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 significantly higher signal when compared with the internal Wi-Fi receiver of the laptop yellow line. In many situations this will be the difference between intermittent, close to unusable internet and a stable usable connection.

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 prinfles and design, and building wireless rpingles with The cylinder portion of the can may consist of metal-coated paperboard. Once again, pringlees has to be as precise as possible, so take your time! Retrieved from ” anteena A commercial Lucent “range extender” omni directional A buddy’s Flickenger-design Pringles can Yagi My modified design Pringles can A Flickenger design coffee can waveguide A coffee can waveguide with corrected radiator placement A Hunts To test it out, take your computer to a place where your Wi-Fi signal is usually very low, and point the cantenna in the direction your Wi-Fi signal comes from.

Every three dB is a doubling in power – that’s three doublings 8x increase!

802.11b Homebrew WiFi Antenna Shootout

If this seems like something a little out of scope, another incredibly simple way to boost your Wi-Fi signal is to create a parabolic reflector to place behind it and focus the signal. The Performance Summary The results surprised me! Clocking it at an inside diameter of 72mm, a the Pringles can is too thin. In the yagis, it didn’t matter much. The readouts from the adapter listing page in the software show an average of around a 20dBm boost.

Your email address will not be published. The resulting setup is a low-cost high-quality high-gain antenna. There seems to be quite a bit of confusion on how the Pringles antenna works and what design category it falls under.
