802.11b Homebrew WiFi Antenna Shootout

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. I tested both the coffee and food can designs, and both boosted my Wi-Fi significantly.

I found myself staring at the products on the canned food aisle at the grocery store. A great tool for drilling holes in thin sheet metal is a “stepped” drill bit “Unibit” or clone thereof. Back up the thin metal with a wood scrap and drill a starter hole with regular drill bit, then wigi the Unibit and simply work down the “steps” until you have the appropriate diameter required.

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.

The length of this probe is very important — and you need to be sure to measure from the bottom of the brass connector to the where the tip of the probe will be. Getting Started With Blynk: Why would you want to make something natena this? 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. One of the first things that got me excited was the Pringles Can Antenna.


Rob used a large, 39oz. 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. antdna

I found that a coffee can diameter 88mmand a large food can mmwere closest to the right size. Getting Started With Arduino: Both did no better than the Lucent omnidirectional. 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.

It is also worth noting that this measurement is to be taken from the base of the can, not the ridge around the bottom. The closer you get to the dimensions from the calculator, the better your cantenna will function.

The waveguides all soundly trounced the Pringles can designs. Once that is done, remove the aerial that comes with the adapter by unscrewing it, and attach the smaller end of your pigtail connector instead. The tiny design makes them ideal for mobile applications such as wardriving. Email Facebook Whatsapp Pinterest Twitter. It was followed by the Hunts Pasta Sauce, my modified coffee can, and the Flickenger coffee can in that order. You can use this tool to calculate whether the cans you have collected would be effective.

It is worth doing this regardless however, as you can expect to see great performance increases from this upgrade alone. 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.


This guide should help you quickly build your own range boosting Wi-Fi cantenna.

Once again, this has to be as precise as possible, so take your time! Even a millimeter off here and your Cantenna may not work as well as it could! Reviewing his plan, I came up with different spacing that he Rob did.

It’s about three quarters of a wavelength in diameter, hon! The general consensus is pribgles a can with an inside diameter of between 76mm and mm work best, with 92mm being the sweet spot. Cantennas may be used with other RF devices such as wireless security cameras.

It’s time to benchmark. While waiting for some wireless equipment to come in, I started looking for my next antenna project.

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 A more efficient cantenna can be made by minimising this length or connecting the cantenna directly to the Wi-Fi circuitry.

There seems to be quite a bit of confusion on how the Pringles antenna works and what design category it falls under.
