[edit]Origin of the name
Cantenna dummy load suitable up to 30 MHz and up to 1 kW
The term 'Cantenna' originally referred to a product sold by Heathkit Co. in Benton Harbor, MI, USA. It was a 50-ohm resistive load used by radio amateurs.[1] However, in the more casual vernacular of the Do-It-Yourself community, it has functionally become a portmanteau of can (e.g. an empty Pringles can, see below) and antenna, since they're used to broadcast (and receive) signals, and not just terminate them.
[edit]Construction
Although some designs are based on a Pringles potato chip can, in reality this tube is too narrow to be practical.[2], however a cantenna can be made from various cans or tubes of an appropriate diameter.[3] Some designs include a pole mount to elevate the cantenna.[4]
[edit]Usage
While cantennas are useful for extending a wireless local area network (WLAN), the tiny design makes them ideal for mobile applications such as wardriving. The design of the cantenna is so simple that it is often the first antenna WiFi experimenters learn to build. Cantennas can even be used to increase cell phone range,[5] improve reception and decrease noise.

I built several of these and had no luck in getting them to work till I put the wire 1 inch from the back of the can.
I made the wire 1 1/4 inches in length at 1 inch from the back and I used a chunky soup can. Works great pointed at a dish network dish as a reflector. Good luck building these.

Why isn't this video more popular? I know so many people who could learn from this!
We have TV channels now, up here in Graham Holler. I get all the major networks, PBS, CW, & ICON as well.........thanks Mr. TV!
This is a Wi-Fi Antenna !@#$%^&*???
NO you dont
Your drawing does not indicate which is the bottom of the can. You stipulated a specific can size but would a larger can offer a higher gain? Since you mentioned that it is directional did you not consider showing this on your PC by moving it around so we can see from your screen just how effective this is. Do you have any idea how distant some of the signals are from your location.. All relevant questions!
Does holding the can earth the signal and how did you support it during use?
Now this really intriges me!

I just spent $20 on amazon and got a great antenna and the best part is no assembly required ;)
I placed some Neo mags in the coil and got my strength all the way back to 54 and can see about 30 networks in range
hey thats a neat Idea how many feet can this signal reach thanks for posting
Best form of recycling. I like DIY because is little anarchistic ;)
@Jason Sweet thats interesting..if u get a chance to take a pic i would def like to see the setup.
not sure what its called, I took a stack of neo magnets and wrapped copper wire around them. My guess is the magnets super amplify the signal passing through the coil. Its actually vertical instead of horizontal
where do you put the other end at, plug to what?
good work
Can This be done with a wireless usb adapter inside the can?
works perfect
it's "shielding" not "shield conductor". Just FYI.
Shield and Conductor are both different things. That would make the shield an oxy-moron if it was a conductor.

Not sure how I got on this video but ended up stumbling upon it.
are you sure you dont keep the soup n there?
Pretty cool
it works I get at least 34 channels thx man
@
Norberto Moreno - How is that possible? This is for WIFI and NOT for TV, LMFAO !!! 😂 😂 😂 😂 😂 😂 😂
thanks! working
I gave a test run building a horizontal copper coil. the connection speed dropped, but it appears to be pulling in data super fast, so I'm thinking the way I made the coil, signal coming in is super amplified. Its much faster, but I don't understand why the connection speed dropped
The challenge I have to overcome is brownouts. I have Iphone 4S using as in internet tether to a PC and one to a Mac. The mac connects better but does not always work better. I have a mobile business moving every few weeks. It is quite common for the iphone to show 4 or 5 bars, the computor to show 3 to 5 bars but the internet is not operating - things won't download and email won't send or download for a period of time. This happens often. I have tried three commercial aerials that have made little difference. Do you expect this will help the situation?
what if you got about 1000 ft of antenna wire and hooked it to the main antenna and flushed the other end down the toilet so it runs through the underground maze of pipes im pretty sure that would boost signal alot or if you connected the cable wire thats running outside along all the poles and under ground for a really long extension.
This video looks and sounds like it was done in the 80’s
Sounds like someone cut a fart at 1:55 - too funny!
I figured it out, my coil Induces current so signal moves through the coil super fast from inductance. That would be gain, introducing more power in any way to a signal. yeah
As long as we use less than 4 watt's we're good, I should find a way to read the strenght in watts from my coil
what is the shield on the side of the hole he's takling about?
Now a day, I use the box to convert my router out door with POE as well
There are all kinds of non-powered antennas marketed as "high gain". Is the term only correct for an amplified antenna?
what do you mean by get a wireless access point if you want to put it far from your pc i don’t understand will it pick up signals from the antenna then send them to your pc with a ether net cable ?? so you can have the antenna more than 3 feet from your pc pleas reply i am very interested
I need an athlete to run around my room with Cantena because the wifi signal in my room is very unstable.
how do you put it in the highest part of your house like the attic with a 3ft cabal
I made desame but did not work,,,,
Show us the result of your invented antenna? Thanknyou
lol im cheap" oh bro.. me too... welcome to the club-
At what distance can I expect to receive a signal?
or even on signal reception.
Oh are you talking about a helical antenna?
good man .... i like cheap things too....
Can anyone tell me how to get an antenna wire, without ripping it off my motherboard? And where can i get Copper?
so good
no. this is for local wifi signal only
I also tried this but i kept getting my neighbors telephone lines crossed , with my hi-def antenna! The nerve of some people ,ha?lol
I missed the part about eating the soup first. It's doesn't work so well with a full can of soup.
[Sod-er] is the correct pronunciation in the US. The L is silent.
Can it work properly though
does this work for usb broadbands??
Cool did u know u can make one with tin foil and a wire to hook in to ur tv
what do i need to do now?
Can you use that antenna to "beam" signal to another antenna?
I actually beam at the nearest star and got a wow signal reply from them.
victortancheongwee HHAHAHA!!!
How much gain do you get?
Good
where's the gain? you're not amplifying the signal to induce amplification.
how much dBi are we talking here?
I spill my chunky soup on my lap
can you drop free internet antenna tutorial
lol for real? What coil are you talking about?
That isn't what I meant.
There is no reason for people to use expensive gold instead of copper.
Does it really work ?
nice
ROLF! Eat The Soup Clean up the can :P nice vid.. it realy works!!
Agreed
What is the max. range for the "cantenna" ?
maybe 0.5 mile?
When mentioning "soldering" people may be put off, if for no other reason than soldering is soo irritating and goofy the way it tends to miss and melt away too much and then adhere to anything except the place where you are trying to apply it (even when you use resin or rosin or whatever they call it). Popular Science has some conductive glue advertised in the small ads in the back pages, not sure if it is possible to make your own conductive glue, but it sure would be easier than "soldering" which is an aggravating little DIY task that makes people like myself cuss, upsetting folks in the room. Anyway mention "no lead" solder (in other words, solder without the metal chemical element "Lead" Pb in it) and good ventilation as well due to soldering fumes. Thank you, i like your design and overall simplicity and avoidance of manufactured parts, use of USAmerica's biggest product --"garbage" --etc. (My can comes from the steel cans in my recycling). Not sure I have exactly that type of cable-- so, precise specs on cable type used, for folks who don't have or don't want to dismantle an existing cable without knowing they have the right specs, would be most helpful. In your description. Also I like your careful explanation of details, tho the video was fuzzy on the drawing on paper, is that 2 1/2 (two and one half) inches from back of the can? Have you tried various distances from the back of the can to make sure that's the best location? Perhaps a sliding bracket mount for testing?
mit dosenantennen kenne ich mich wenig aus????????
it s how ?
cites from Wikipedia....LOL....just who is this Wikipedia person and how do we get to meet him or her
hee hee hee, ..."buy a can, eat the soup..."
Where do you plus this contraption in at?
1.2 inches hmm i think its better explained 3 eighths of 10cm or two thirds of 100 mm
I just pretended that it's Sheldon :D
i just want to see the result..before and after..wasted my bandwitch watch this..damn..
Oh....
And then WHAT...?
YO!!!
maybe it will work. just try it!
you can just put a paperclip in the tv aswell
This is a Wi-Fi Antenna !@#$%^&*???
don't make him feel bad about himself I had a dream once believe it or not i had a dream about making a tv receiver too.
i invented the paper clip antenna
This is a Wi-Fi Antenna !@#$%^&*???
I never realised, until now, that it was possible to record youtube audio on a shellac 78rpm record.
esto puede provocar una bomba nuclear, cuidado chavos, equis de (xd)
Does anyone else think he sounds like Sheldon from Big Bang Theory?
Refer to my original comment's third sentence.
Great. Now look up how to make a gadget that enhances video quality
if you had a bit more patience and built one yourself you would still have the $20. you may need the money someday.
tests? proof?
Being cheap is one thing but sometimes it cost more in the long run. All that BS your going through, damn. I made my own. I got some old fence tubing and put it together for a pole. Then spent $25 on wire nut bolts ect. and made a antenna. I get some 30 channels. And it's done and I do not have to screw with it. There's lot's of antenna designs here on youtube.
+William Wynn tell me more
+William Wynn William, I read a comment you made 2 years ago online. The challenge I have to overcome is brownouts. I have Iphone 4S using as
in internet tether to a PC and one to a Mac. The mac connects better
but does not always work better. I have a mobile business moving every
few weeks. It is quite common for the iphone to show 4 or 5 bars, the

This happens often. I have tried three commercial aerials that have made
little difference. I have looked at the tin can aerial. Do you expect this will help the situation? Have you a better easy to make idea?
i would like to know more about the antenna idea, thanks
Tooo much talking dude.....just straight to the point.
You really think people would get gold and use it on wiring?
you can do this for a tv with an old cable wire and a coke can
This is a Wi-Fi Antenna !@#$%^&*???
"cantenna" :D
@xbarryx08 When i read this i bursted soda all over my screen lol Rofl!
unscrew it, maybe?
i connected a Coke can to my TV... all i get are Coke commercials :(
?????
Wow cool any kind off can can work
uncle i don't believe you .
The "L" is silent in the electronic school I attended.
This, from a dictionary: "sol·der [sod-er] "
In brackets is how it is pronounced.
you should more voice language provied like hindi
will it work if I have aids ?
das habe nicht ich so geschrieben!
gold beats it on electricity not to pop you copper bubble
why do you sound like the guy that builds amps veg something
For the love of God get on with it. I can't do this anymore. I want to know how to connect to the computer but he will no get to the point.
