WiFi Directional antenna fix, from Aluminium can.

This is a simple device anyone can make, that should improve your reception quality and or strength.

An aluminium can is the basis for the design, therefore making this a very affordable project to try in your spare time... Goodluck!! :)

Step 1 What is it??

To often these days our wireless internet connections are being corrupted by external influences, some of these are buildings,electronic interferances not to mention the rest..

This is a simple device made from any aluminium can (alcoholic preferably), cuts down on some of these and helps focus on a directional point..
This may not be applicable on many modem units..

Although I want to share this I also ask to you read the following. Just so we are clear.. :)

Warning: I am in no way responsible for any damage caused, by your using of this device in any way. You do this at your own risk. This will possibly void your warranty on your device and or render it unusable. It may also spontaniously combust and blow up everywhere causing damage to property which I am also not responsible for... YOU DO THIS AT YOUR OWN RISK!!!
Then again it may do nothing, because its just a sheet of aluminium... LoL


So lets get started!!
What will we need??

I tried this just after picking p a $35 NetGear G router. I had 1-2 bars across the entire house, through many walls from my desktop. Now, thanks to this simple and inexpensive creation my signal has been boosted 2x stronger to 3-4 bars. I pulled my own tweak on it though by increasing the angle from 100degree to about 130degree as my guesstimate. Over all, like it!

I am glad you found this of assistance. The angle suggested is also just a rough guide. the exact angle will depend on your individual device. I have also had alot of interest in the unwired internet community. (The modem pictured is the Unwired wabbit) Without this lil' device I am unable to connect to the internet. Thanks for your comment. Perhaps I should be contacting NetGear??!! ;)

And the reason for the SPAM links?

[rayfalcon]

it didnt work with my indor antenna which is a philips 310f and a 12 db 50 - 900 mhz am/fm-tv(uhf /vhf) signal ampifier any suggestions I miss ion tvstaion channel 54 here and wbn and wgn?? anyone got any ideas?? email them to me personally at this email address with the subject of television antennas [e-mail]

[Lftndbt]

Do you have a directional signal being sent from a single location? Or is it from multiple signal points? Open the can up the a flat sheet, hold next t antenna, let it naturally spring close slowly while holding very still, if there is no responce then forget my method. Are external antennas not a possibility to you?

[rayfalcon]

ok i do have multiple directional signas if that means that I am tying to ick up several staion with the same antenna. lol on the opening the can up the flat sheet ive already tried that lol and my amplifier is an electric one which is abt 3 feet away from both antennas. On the possibility o exteral antennas ...weeell lol to me yes even though id rater not (ill expain in a minute), but no they're not really a possibilty anyways cuse m livin with my mom in her trailor on my land... k now for the explanation lol i know im typing a book already so ill ty and make it as shor as posssible te reason i can but cant and ould rather not is because lightining can and will strike outside antennas epecially if they are electrc or steel and some types of alumminium, and this would bea major disaster for us as we can not an do not have any insuranc on the land or the mobie home in which the antenna would be feeding to ..... i know i know lol everyone says attach a grounding rod to it and that will eliminat the lightinings effect on any house and tv damages ....Nope been there done that ad my 2 story home to complety burn down even with a lightining ground rod attached to my old 50 foot ham/sw/tv/fm antenna. thats why im really leiry of outside antennas now and stick to small indoor ones...however I would like to make or find a free antenna that looks like thi to use for my tv in case this confuses you i will include a link to show it in complete view and better details for you ||-| |-|| | | | I want to be able to get channels 10,12,18,20,21, 3848,54,and tbn which i think is channels 75 ad or 78 on uhf one of these should do it but so far i have 3 atennas bought and not a one will get them and 1 of them says that it will pick up uhf stations 14- 95 and it doesnt not even with my amplifierhooked up to it

I've been reading a LOT of this WiFi stuff here on our extraordinary Instructables.com and was wondering if anyone has tested the strainer method against the coffee can or pringles method and also against using an old directv satellite and such. Which one would give me the best reception? I'm guessing the satellite dish but I am new to this. TIA!

[Lftndbt]

Depends if you are wiring it up as in the terminal, or just using the dish to refract like mine does. Coffe can and pringles have their downside as they only recieve a small amount of signal sent, yet of that next to none is lost... Preferable I prefer to use my method as it direct a small percentage that would normally by pass the aerial towards it. It however does not block any signal out like the cantenna.. Hope that was help full..

Looks good, but can you embed your video instead? More people will be able to watch it. Instructable on the subject here.

Thanks for your help! ;)

3: Beer cans are taller than coke cans so provide more reflector surface 4: Beer is (I believe) less acidic than coke so beer cans may have a different makeup, eg more steel/less tin/less aluminium/less plastic coating on the inside/whatever else that improves its reflectivity 5: Drinking one can of beer has a mild depressive effect on your nervous system, reducing slight natural (or coffee-induced) shake in your hands, so you can hold the reflector more steady and get a clearer signal :) Any other questionably scientific pseudo-explanations around? I've already tried this with a 330ml can but it doesn't fit around the tiny antenna on my PCI wireless card :(

[Lftndbt]

Bad luck on the, not fixing your antenna...

Sounds like you have been experimenting too....
Had any luck??
I like your pseudo-explanations for the alcohol... LoL... fantastic!
Nice to see someone else shares my sense of humour... ;)

[GorillazMiko]

Cool, looks quite easy to do, and small!

[Lftndbt]

Yes, yes it is. Thanks for your comment.!
