How to build your own cantenna to boost wifi range

Date: January 5, 2012 |admin | Ecommerce

Just a vid of how to assemble a cantenna to increase the range of your wifi adapter. You can purchase everything in a “cantenna kit” on ebay for around 25 bucks, minus the tin can but thats what makes it fun and creative. Check out my graphic design work here at my online store where you can buy anything from shirts,hoodies,hats,skateboards and mouse pads plus loads more.

this is sickkkk

this looks legit as fuck.. how much better does it get though?

@pues13 It all depends on your line of sight to the wifi router. If there are no trees etc between you and your “neighbor” then it should increase signal strength greatly, either way you should see at least 2 more signal bars plus chance of finding wireless networks you couldnt normally with just your wifi adapter alone.

gayest song ever

Unfortunately, there is more to this than meets the eye including the diameter of the tin, the length of the vertical element, the polarity of the neighbour’s Router and the distance from the back of the can to the vertical elemt. All these will have a huge bearing on the success. Your mileage may vary and you might be lucky. For info, I study antennas and their design and have made many of these. I prefer simple yagi antennas for repeatability, however Can-Tennas look really neat, I agree.

were do u find the wifi USB adapter [at a shop]
(plz respond!…)

@shadowtaco28 you can find an acceptable usb wifi adapter on ebay for around 20 bucks, thats including shipping. Just do a search for wifi usb adapter then filter the search to least expensive items.

@ gitanox3 & 6rockthehellout6

The song is called “The Farthest Star” by the group VNV Nation.

how do you calculate location of hole in the can and length of copper wire?


Date: March 9, 2010 |

what’s a good can diameter?


Date: March 15, 2010 |

or get a better adapter?


Date: March 16, 2010 |

I make these, and I did all my math, first, the dimentions are critical. Use a large can, with a 3.25 inches. Make the hole in the side so that the center, where the element will be 2.5 inches from the bottom of the can, and make the element so that 30mm is exposed, or 30mm long.

@ps2hacker I don’t know if you are a HAM Radio operator or not but if you are.. Do you have any equipment that can measure the SWR of one of these? I’d be interested in the results if so.


Date: March 17, 2010 |

No equiptment, and not a ham, but only because I couldn’t seem to get the morse code, I actually passed the rest, though. I just used the old given variables, that is to say if were testing an antenna, Id use the same mounting point, direction, coax, radio, that I was familiar with. There shouldn’nt be any swr’s, though, the standing wave propagates in the can, same as swr’s would in a cut coax.

the diameter of the can will act like bandpass filter. think of it as only certain size radio waves will fit in the can. I calculated that the ideal size range for the 802.11 channel band should be 80 to 90mm. The only standard size in the grocery store is 3.25″, like a tuna can. Large saucecans work. 3.25″ comes out to like 83mm, nothing else is in that range at all, so I worked with that to get those measurements. These work great for me.

And you could just stick the whole pigtail and N connector by just making a hole 2.5 inches from the bottom of the can, and shoving the the stock antenna with the usb card through, and taping the whole usb adaptor right to the can, It will work better, if you get it in just the right spot, since it eliminates the pigtail’s loss. And its way on the cheaper.

VNV Nation… niiicceeee…..

this is a good one. is there anyway you can do it with a laptop which already has a built-in wifi adapter without using any USB Wifi adapter?


Date: April 19, 2010 |

Kinda reminds me of a very very basic RF waveguide. Awesome music BTW. VNV Nation kicks.

@ps2hacker ahh me head hurt im sart at things like this but its too much ouch

Irony! They say the same thing about your mom. Fucking fagbait; you’re going to be the first to get eaten in the Zombie Apocalypse.
