The coffee can antenna shown has a problem with the design. The ridges actually scatter the signal inside the can. It's best to use a smoother surface.
Now take it up to the next level. Mount your cantenna at the focus of an old satellite dish in place of the LNB having it aiming into the dish, then aim the dish at a distant WiFi source. Aim the dish about 25 or 30 degrees (not exactly sure) below the target if your using an off set fed satellite dish where the focal point of the dish is not directly in front of the dish. UA-cam: AmateurLogic.TV Episode 10 for more info. This makes the cantenna WAY more powerful than the cantenna alone!
Most pringles cans are made of cardboard not out of metal like the Maxwell House coffee cans. Cardboard is more of an insulator than a conductor for microwave signals.
A parabolic reflector will do fine for simple home use. I made two 6 inch reflectors for my router out of household materials that give me a combined 24dB of boost.
mubarake, The connector that you should use on the cantenna is an N connector. I am not sure what connector you will need to put on the other end of the cable is to connect to your laptop card, it depends. You should have the cantenna with a femail N, a LOW loss cable like LMR-400 with an N male on one end and whatever connecter you need to connect it to your laptop card. N femal:Nmale:cable:lap. card connector:laptop card. He is right about the cable loss! KF7AOL Ham radio op.
Regarding stealing WiFi, anytime you turn on a laptop that has WiFi (most do), and you are connected to a WiFi node (most are in a typical neighborhood with several unsecured nodes), you are NOT stealing a signal. Many people will be connected to such unsecured networks without actually using the node. Does the FCC consider this a violation? I think not.
Actually guys, even if it is the same frequency it's only radiating 0.150 watts or so. That's right, 150mW. A microwave oven is between 700 and 2500 watts. People use up to 5 watts output on hf handheld radios.
@MosesInTheFlesh no braodcasting a wifi signal that other people can connect to isnt what u use a wifi antena for, u use the antena to connect to a signal that some one is broadcasting
Haha man, My grandparents have an old CB radio antenna also thats like 30 feet high! We use it for a lightning rod on the house haha. I wonder, can I use that bad boy to brodcast my wifi!?
FCC doesn't have any jurisdiction over signals solely within States or non commerce signals between States. Read the statutes if you're going to talk about them.
Commercial WiFi yagi antennas do not cost several hundred dollars, like these guys claim they do! You can find them online for anywhere from 25 to 100 dollars (most of them). And the performance will blow away this Pringle's can contraption.
@@Pterodactyl-kn3ve Some proprietary ones may have been. But many of these yagi antennas were used in Amateur Radio (Ham Radio) applications, and they were relatively inexpensive, and easily modifiable for WiFi frequencies.
they say bullshit about the cable... What they really need is a cable of the same impedance of the air and the network card... A coaxial cable can be ok if it is at the same impedance....
Good Lord - if the guy in the solid shirt wants to be a stand-up comic, he should go somewhere else! Couldn't listen to this, that guy was so fricking annoying!
Er uh it won't work worth a shit without the proper math, the piece of wire need to be approx 1/4 wavelength of 2.4Ghz (around 32mm w/velocity factor) and 1/2 wavelength from the back of the can. These are just guesstimates and it should be tuned on a network analyzer for minimum return loss (SWR)
From Rodney Dangerfield this type of dialogue is admittedly amusing, but leave the contrived badinage to the drones of the TV audience. We want the TECHNICAL INFO, plain and simple. Give that fatty the hook, he sucks. It's amazing that I ever put up with dreck of that type.
Ok rather than build suspense or make it look like I'm ducking the issue I've skipped crashing to provide citations. Law is extremely convoluted and until one sits and examines numerous section definitions it may not become clear that one has been hoodwinked on a # of issues. 47 USC Sec. 151 dictates PURPOSE.

"FCC doesn't have any jurisdiction over signals" I know the FCC regs and YOU are very WRONG. The FCC regulations control all transmission accidental or intentional. Enforcement is another issue. You may get away with it. Violations are rare. If you do get caught, the fines and penalties, including Jail are substantial. A guy in Florida went to jail for FCC violations. If you use the coffee can antenna to steal signals or do anything criminal, that is another deal, criminal law kicks in.
SHOW ME THE REGULATION? DARE YOU I'm a Ham & operate commercial radios from HF, VHF, Microwave & SatCom all over the world. The rules are simple, NO. USA, if you have a radio transmitter, intentional or unintentional making RF/EMF of ANY POWER, the FCC, has jurisdiction. 100mw or less, inside your 4 wall, no complaints, no foul no problem, fine. A complaint, antenna too high, add power or steal signals, you're in violation I guarantee 100%. Get caught penalties are harsh. Ask a lawyer.
I'll post the codes within the week when time permits. You could have posted them yourself since you claim to know them but instead you've merely made more claims and shifted the burden to me. I'll go through my notes and the code and respond here so others can go look at the specific sections rather than wade through the code.

ooohh i miss those beautiful days of tech TV, good old days!!!
Why isn't this video more popular? I know so many people who could learn from this!
Fsociety where you at?
Holycrap did I stumble upon an earlier version of Leo Laporte's TWiT?😅
this is the21st century..live with it... Wifi :)ownes one of the best inventions since the spork :)
13 years later.. this comment has been read and still holds true :D
Who came here from Mr. Robot? xD
me :)
here
lol
i haven't watched the new season :o, OMG a can of worms? awesome.

im so glad i got to listen to your inside jokes.
hey does a wireless trendnet 424ub does it work because i want to know how can i improve my signal with that wireless trendnet 424 ub

RIP Tech TV
@TNFlightNurse before it crapped out something called G4TV. I missed Kevin Rose's "Dark Rose" hacks.
@2:05 Did Patrick just say bitch on TechTV? Awesome!
heey leo laport man i miss that show

Is possible to hook up a wifi antenna to an xbox360
Haha man, My grandparents have an old CB radio antenna also thats like 30 feet high! We use it for a lightning rod on the house haha. I wonder, can I use that bad boy to brodcast my wifi!?
i love it lol
2:06 lmao!
part 2?
get to the damn point. I thought I had Attention Deficit Disorder! Can't believe they had their own show

working man!!!!@
YEP!!!
lol you have to somehow tap into what gets put into the tower and then input your own wifi signal to do that.
Thumbs Up if you want Call for Help back!
he didn't say that in the video, he said it was one ended. ;D
the guy in the green shirt talks over the other guy when hes explaining how to make the antenna.
@OneBluesAvenue Leo always was, and IS kind of a douche. Patrick Norton is a cool guy who I always enjoy. He's on Tekzilla now.
thank you for that comment :L now if only they would listen.

In the early days of Wardriving, initial rollouts of DSL and netstumbler they did cost that much.

backtrack
No bullshit at all if it is a visible line. I got 3km behind some trees!

Me hablaron de no se que antena preingles pense que era un modelo de antena pero se trata de las autenticas pringels XDDDD
2 or 3 aprox.
lol guy on right from revision3.

so divide by 2 which is 2.5 miles :]

why would u want to braod cast ur wifi? maybe use it as a wifi reciever but not broadcasting lol
nup, wrong wave length and everything.
Why waste $1,000
Google search "satellite dish antenna"
You can get 200 miles out of that; 50 if you aren't in the jungles of Brazil
do tv in the same way
