here’s a guide for making an antenna for your access point that beats the pringles can on a number of fronts. it’s easier to assemble, requires no pigtail and no modification to your ap, and it is claimed to have better perfrmance characteristics.
the reflector design was originally intended to increase privacy, but the nice side effect is that it dramatically increases gain in the direction it is facing:
power normally transmitted in that direction is “bounced” forward. Therefore you have more control of where your signal is going when using this reflector. That feature of this antenna can be used to enhance the privacy of your wireless network and that was my reason for designing it in the first place, the rest is just gravy but it is very real and rather tasty gravy. :) Please also note that antenna gain is preferable to amplifier gain because it adds to both transmitted and received power.
the best part is that you can make one basically for free. grab some aluminum foil, cardboard, and a scissors and get to work.
RF is fun to play with.
This is a great example!
I’m gonna make one. Will post results soonest.

whats up with all the old hacks being reposted?
Acemilo ! i am sure in the time it took for you to reply like that, you could have sent them a better hack for the day, link :-) why not show us what your into ? or find a link for a day
I want to get started with a hobby in electronics. I have an MS in CS, so I wouldn’t mind learning a little microprocessor programming as well…
Anyway, a few questions.
What sort of tools will I need?
I know I’ll need a soldering iron and multimeter. Suggestions on these that work well at a decent (or cheap) price?
Any good resources (websites or books) for a beginner like me?
Anything else I should know?
Thanks!

did this to my router, got 10db improvement at 100ft. went from kinda connected to pretty good. i used the cardboard from the box the linksys came in and a couple of soda cans for the reflectors.
Ideal hack, only takes an evening, doesn’t cost much and is usefull. I don’t think you can ask for more than that!
if i had a flag pole, could i use the pole as an astenna? idk how u would do it but it soulds like ud see so proformance increase
I just did mine, and although I haven’t measured it, I was able to connect from places where it was impossible before!
this is in orielys wireless hacks Not New It works but pringles can the best or make a conection in your heating and cooloing duct with type N-contector use your whole HAV duct system as a huge ant. use the sys concept as pringles can. I use my laptop any where in house and around the yard working on mod for a repeater to make signal go farther.
Of course these small reflectors best suit the AP WiFi server! They’d perhaps beter work in conjunction with a client side antenna such as celebrated USB Asian cookware signal boosters that show 12-15dB gain. See => http://www.usbwifi.orcon.net.nz
N.B. Although these indeed work well for most APs, the downside is that the omnidirectional signal usually desired for many WiFi applications (offices, libraries, campuses, wandering PDA etc) will be weakened in some directions. They could be ideal in a home however, since links are then likely just to a few indoor locations – study etc.
It works like heaven for me. I can find signales from places I never had found before.
COOL STUFF
Yeah, I tried this a few weeks ago and adapted it for my dad’s cell phone and it worked really good.
I have a Sony Vaio Laptop with built in wi-fi, no antenna, What can I do to get a better wi-fi signal?

I tested this with a crapy put together one made of cardboard for the half circles and a sheet of aluminum (from disposable baking sheets) and I tested and noted results. I have the router and reciever about 75 feet apart with walls in between.

I have a coffe shop about 150 feet away from my house. Is there any way i could use a satelite dish to increase the wifi distance of my psp? Thanks.
thats what i want to know for my psp. #20
At first i thought it wasen’t working and a load of sh(weight can i curse) but i knew it was doing something when my segnal went from 55% to 25% so i kept playing with it and made it quite focased and now my neighbor gets a 75% signal striength. i just had a non workable shape at first and then pointed in the wrong direction.
I have not seen this one before, but thought up a similar one. My idea was to make one the size of a volleyball net, but with window screen wire. The trouble I had, was trying to figure out how to make it form a parabolic curve.

I have an old antenna that was never used again, it was used to get channels on the TV do you think this could be used in this project??
Great articles & Nice a site�.
: P … Just Telling: P: D
Nice article, I should say I never scan one thing that summed it up thus well. One thing like this should be browse once in a whereas, to remind us of some essential concepts.
