The size of our choice is important, as there are set fundamental dimensions which allow the cantenna to work. Neither of these methods are ideal, and I would recommend using a stepping drill bit to make this part easier. Why would you want to make something like this?

I mean they stomped them into the ground on signal strength – as much as 9 dB better. The performance is good, the cost is very low and the skill required is minimal. 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.

Have you built a Cantenna in the past? The cylinder portion of the can may consist of metal-coated paperboard. The math for computing correct sizing of the components in a waveguideWiFi antenna is simple. To do this, I setup a wireless link and changed only the antenna- recording each antennas’ performance under pringlew conditions.


Of the waveguides, wwifi Nalley’s “Big Chunk” took top marks. 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 A cantenna can be used as a satellite dish feed horn. Once again, this has to be as precise as possible, so take your time!

Pringles Can Antenna Turns 10

I would advise cutting anhena slightly large piece of wire to begin with, and soldering it into place inside the brass socket on the prngles of the connector.

Perfect for when your own internet goes out and you want to be able to keep surfing in your slippers! A friend of mine built his before me and looking at his finished antenna got me excited to understand the theory of how it works.

If you need to extend the distance between your computer and the cantenna, I would recommend using a USB extension cable. 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 pringless be.

Views Read Edit View history. I tested both the coffee and food can designs, and both boosted my Wi-Fi significantly. It’s about three quarters of a wavelength in diameter, hon! Look out for cans pringlez a 92mm diameter that are around mm in length, though you may find something exactly of that size hard to find!

To see if I could improve upon the design, I built mine with corrected spacing. 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. 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.


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

Even a millimeter off here and your Cantenna may not work as well as it could! This article is about a microwave antenna.

It is worth noting however, that this boost will be directional depending on the orientation of the can, and while it will help hugely in one direction, it may limit the strength of the antens in other areas.

The Shootout My plan was to get relative performance measurements for various designs including mine of homebrew antennas for Getting Started With Blynk: 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.

Archived from the original on My three waveguide designs, which utilized the correct theoretical spacing, out performed the Flickenger Yuban coffee can handily.
