Hi! did anybody try DIY wireless antenna before?does it work?please give me some comment.TQ..
http://www.usbwifi.orcon.net.nz/

i was thinking to diy one also, my antenna had lost... so bad

so many words head go spinning...

Err theoritically adding a round shape wire gauze around the wifi adapter can help to improve signal but on reality dunoe la

Actually, a tent will do....

Last year my bro wedding, we rent a tent and put in the garage...
I was using Jaring WiFi that time and its quite bad signal, my game will dc alot everyday..
But the time the tent was there for few days, my game never dc....

so wacky angel is actualy suggesting to buy a big tent n put it in our garage for no use... thats not cheap diy la

uish. is it really works just with the diy antenna?

like tat also can...

issit mean more reception? more coverage?

maybe wat he meant was putting something that could extend the signal of the antenna la
juz like i used to attach a wire to my small tv antenna to get a better signal

Actually, the curve plate will only act as a reflector. Reflecting the signals towards the receiver.

It does not add 12dB to 15dB to the receiver. But concentrated signal "Could be" around that much gain.

However, I don't think it'll work the same magic when it's in transmitting mode though...

It should work too, as it will concentrate the transmitted signals in a single direction. But of course must be correct direction la...

I think he just got lucky with the tent.

i been reading bout this but for me its just seem impossible.. anyone had test it before?

nothing to do with casing, belongs to networking forum

It's ok. It's pretty interesting n has got to do with modding parts for the PC.

If u guys do a bit more googling u'll find a vey nice n simple wifi booster mod called the Pringles Cantenna. U know the Pringles potato? Ya that Pringles, no joke. Just get the can after u finish eating, put the antenna in it. U need to measure exactly where to position the antenna inside the can n ure done.


Google this-> Cantenna.

I know you can direct your antenna's wave in a certain direction you want using tin foil and something semi circle. Building one...not sure if it works, or has MIMO function

My friend has did a DIY wifi...he told me tat, in terms of signal is more consistent than using the laptop built in. other than that, everythin is the same.

There was a bunch of physics students in USM that did their final year paper on this topic, seems its actually effective. If I have time (which I doubt) I can go look up their report somewhere.

Hi!I have DIY my wifi antenna yesterday,i use aluminium wok cover 12',reception very good cos about 100 meter from my shop got restaurant with wifi n no need password.Speed around 55mbps-36mbps.Wifi adaptor rm 55 aztech brand-wok cover rm12.HAPPY DIY.....

interesting thread. i have already modded my usb wifi b4 also with a cookware item. (dunno wat name, like a penapis minyak or sumthing). n yes, it really does help improve signal. i get bout 5-15db extra. not much different though. but that was last time when i was staying in condo n wanted use condowifi.

myvi33322 i rlly interested to noe how u do dat. a screen shot perhaps??
100 meter away ?
in terms of da,t u still need to consider ur Wifi aDapter TX power .. i doubt ur Aztech adapter produces high Tx Power, perhaps im wrong.. a screenshot perhaps??

eager to noe

Hope you can make one and tell us the results.

Yes, it works. I am using this method to improve my wifi strength

Without the alumminium foil, my wifi only got 2 bars. With it, it got 4 bars.

I had made mine using a 15" aluminium kuali and the sad thing is: I use it in my campus accomodation and the wifi access point is actually about 150m to 200m away and it is blocked buildings and also walls, although I pointed my dish antenna to the correct direction, it still didnt get any signals.

Material also taking into consideration if you making a dish antenna, for example a steel one may reflect better than an aluminium.

For those who have nothing or few things in between your antenna and the access point, you may happy with your work result.

i'm using toilet rolls cut in halves laden with aluminium foil from the kitchen. boost is slight but it does help since i live in a 3 storey house.
Got this from techtv astro channel 13 last time. cheap and good .

Maybe mod should make this a pinned topic as this generates quite a lot of interest. It is a place where we can share our experiences for those who might want to build one.

Any one second that?

I've tried making a cantenna before, but with bad results due to suboptimal can size and bad craftsmanship. I ended up buying a yagi, which worked heapppps better than the original rubber duck antenna that the wireless bridge came with.

Seriously, just try finding The Right Can in the supermarket.. you'll have a hard time I tell ya

True! And with all the calculations you have to make to find the right 'setting', it would be a nightmare.

Anyway, it would be a good project for those who really like to get their hands really dirty.

How much did you buy the Yagi antenna?

Hey guys.. I didn't know there are people interested in this here.. I had been doing it by myself for pass couple of months and upgrading it.. And then I bumped into this thread.. Lucky me.. Well to tell u the experience.. It works on my Maxis broadband! U know the RM68 package kan? Yup that one..

Hehe.. Previously I bought a small round metal tudung saji (food cover) and covered it with aluminium foil. I then places the antenna through a hole I made in the center and it worked.. I gained such great signal.. I can't say it was boost though.. But I got better signal and speed.. In gombak area.. the maxis broadband line was pretty ****up... so it was not consistence and alway dc all the time.. Later by doin this, it helped me..

After a while.. I had the idea where my fren told me to change the current diy antena reflector.. I just bought a roll of aluminium foil and folded it into a rectangular shape with couples of layers.. Then I placed it standing up behind my broadband modem and direct it towards the tower.. It gained lots of signal and raised my speed. Previously it was low.. My download speed was from the average of 1 to 10 kbps raised until 40-60 kbps... I was overwhelmed..

Try it.. If only my nokia navigator was not stolen last week, i would have put the pictures here.. Sorry for that..

AWESOME
Really getting into the mod frenzy

this video teaches us how to hack a wireless antena, just a simple one

I watched the video and opened up the antenna but unfortunately, it was already originally modded!

It was an interesting and useful video!

hey adyalisme , any pics of the DIY anthenas ? coz i am usng maxis and staying at genting klang setapak ...

I cincai solder and attach a karaoke mic wire to the PCI wifi card.
From average 36Mbps without the "attachment", I got stable 54Mbps~!

Haha, antenna mods. Luckily for me, I just needed to increase transmit power so that the whole house could get it. Increasing the signal bars sounds fun though.

Strange things work wonder. I used to do this with my television.

i diy my antenna for izzi net which use 1.790-1.795ghz, current in working condition but still need some improvement

How your ensure your DIY antenna is working at that frequency range?
Is there any formula or method to calculate them out for your own design?
How about if I want to design my own antenna for 802.11b and 802.11g?
Thanks

anyone here try windsurfer? hehehe

I tried, and it does helps a little in signal strength enhancement on my D-Link 7dBi antenna.
