Practically Free DIY WiFi Antennas
Monday, April 7th, 2008 running time 21:01
Cut and past your way to better WiFi reception? It costs pennies and takes the fabrication skills of a kindergartner... then bend a 6dBi Omni and a 10dBi directional out of copper wire!
David's got a bit of trouble getting his WiFi Router signal to reach every corner of his house... one of the easiest fixes ever isn't a trip to the local computer store, but a trip to the kitchen for aluminum foil, then to the home office for a manilla folder and a glue stick.
It's the infamous Ez-12 Parabolic Reflector, hosted at FreeAntennas.com.
Here's the EZ-12 template link.
Omnidirectional Antennas = radiate signal 360 degrees...
A panel mount or surface mount female N connector and 300mm of solid core copper is the heart of the Home-brew Compact 6dBi Collinear Antenna a slick e found on MartyBugs.net.
Directional Antennas = generally concentrates your WiFi in a single direction.
We went to the Seattle Wireless most excellent collection Antenna HowTo for the SardineCanAntenna a biquad you can build with or without an N-connector, at least at the antenna end! (just search WiFi Biquad to find a host of construction ideas!) You don't have to use a sardine can, just about anything will work as a reflector, even a pressed CD... it just needs to be metallic and around 150mm in diameter.
There are quite a few more WiFi antenna designs out there... these are just some of our faves!

You're gonna need glue or contact adhesive. And the important secret ingredient which would be aluminum for recycled properly. So if you can kind of rock this whole concept -- to make a -- much for that with a template. On top of the Manila folder or pretty much any kind of cardboard want to use and for the backing of the preamble of the actual reflector part. They're going to glue. Aluminum folded back and pretty easy so far they're gonna get out for a committees before scissors or some nut cutting device. You cut -- into the space as war. And then you can search. The tabs.

" All right the next two antennas are talking about here. Have something in common and most importantly that they require -- Wi-Fi card of the abilities and external antenna right here basically external antenna Jack's gonna be in the car or you were brouder. And those are gonna very work and get into the specifics. Except to say that both these antennas are built using. And end connector and that's basically -- connector right here. That's connecting to an SMB connector and in this case him -- kudos -- you are. Card usually you're gonna find these on line if you're lucky to get a pretty sophisticated computer store in your area that you can find. He pig tails which is this device here that goes out from your -- And into an external antenna. Okay first couple going to build an army directional antenna -- about static compact six TV I believe your antenna ends up looking like this when you're done. Let's talk about what you're gonna need -- about time. Twelve inches thirty centimeters 300 millimeters. Copper basically the copper -- household wiring its solid core this is twelve gauge wire. You can even in the connector you know -- findings locally media if you have a ham radio were pretty electronic shop nearby this is the end connector can look great panel amount free chassis balance. And connector panel answer especially good if they don't have the force crews. -- the -- on on the bottom. -- gonna needs and -- first to measure the familiar millimeters to the all of our directions on this are millimeters. Here and -- some pliers before bending. And we a couple of different. Fancy players we found that were kind of useful but the reality is that most -- with a parent needle nose pliers. And most of our cutting with a parent and cutters to figure need one -- something around we used a shall be -- and at 1112 millimeters in diameter to make your loops around. You're also going to need. Some type of inexpensive. PBC to create a cover for that otherwise its really easy to. -- the antenna which is not gonna make you happy. The key to making this antenna is basically precise measuring brain and it's a key to most antennas and what's interesting about this design is -- creating. Any half wave antenna. A three quarter wave antenna any less than three quarter wave antenna that basically produces a capacitance factor which gets -- the ideas and neither understand nor particularly want to get in depth on. But what's interesting about this is basically. Measuring your -- start out more wired -- you need because of something really more refined in embarrassing about ending up with the perfect management at perfect measurement and being six centimeters to -- top. -- The primary tool this is gonna be. You're calpers. -- We're used to -- right here. And we're gonna set the account person first measurement we -- be easier to start from the top rather than the bottom of the cable and we left a little bit extra. Just so we had something to tune with the case things didn't go out. Didn't go to well our measurements. Haven't we found out is you have to remember to take into account the radio saying. The basically the radius of the wire and you've ended and the small of the players use in period tired of the radius is gonna be. But remember that you're gonna have to take the distance. You know appear to an end -- with. Basically just senator of this spiral is going to be as it. -- up to the next level is gonna be your measurements if you want for 61 millimeters from the top of the connector. To the center of that you're gonna have to play around with a link and he -- write it can be a little frustrating and it's pretty easy with time. Withstanding the rather than trying to start spending from here start spending from them about the middle of -- want to make that makes about a 1000% easier to bend the loop around. And keep spending the loop a little bit farther. That you need to you you're gonna be some spring back. And -- it a little tighter and you can play around with that adjustment basically cut everything for toppling upon there. And we're gonna travel suppliers. Who depend that are and here see if that works. And secondly it is where things a little bit more interesting we're gonna -- just for calpers. 291 and half millimeters. Remember taken account the radius is gonna take. A few millimeters to retain about three millimeters off that's. Pertinent than the surrounding him."
" for that third band. Which looks like it's gonna be a little short of the uterus and find out. Millions -- 91 and a half that's -- all right. Obviously I'm not the most precise of disown me the -- actually built the original in its magnificently perfect states. And -- for a third almost sixty your basically your third link the antenna the bottom like the sixty -- Millimeters. Several websites and -- and connector. After -- who -- measure from. The top the end connector into there and it's just barely going to be enough. Little uglier than I'd like I think it'll work and just like -- or 61 millimeters and there. Not quite perfect but it."
" And we soldering this you want to basically uses a little bit more heat than you think reason likes him he wants this war probably way too much but this units you can melts -- on this and connector. It's hard enough to. Notes -- on there you want to keep this thing -- Indeed the heat off as quickly as possible because this plastic. That insulates. The core. Will -- it won't really quickly which can be enormously frustrating. So community when enormously frustrating looks like. You know -- red tape that -- things have gone desperately wrong. Is he really core on this literally just punched right -- right out can diskette to opt. So remember he quickly and that it got out of there is so siren. About this down a little bit and basically the direction want to solder and there please don't yell at me in the forums because. I'm simply a few tiles. That my soldering technique that is but I found works for me. And we're gonna keep this thing up as quickly as possible to remember we don't want to melt the plastic in certain. -- Apparently not in this little bit too because I suck publish an outsider. But it. Looks like we're still okay of their 61 millimeters it's we'll try to later network. So the reason were were making these measurements approved sites and at least trying to and restore about a millimeter over on this. Is. What you're creating here is basically our quarters or -- for three quarters most common -- quarterly antennas right seen aerial with a CD on top of me. Car or truck it's most likely quarter -- Which basically gives you calculate. The quarter of the wavelengths. Two point four gigahertz between 400 Hertz which converts into. -- you know right around 120 millimeters and listen and try to post this -- I am. Two in this case it's three quarter. Way which is 91 and."
" And assess halfway through one millimeters means they forward it via 120 millimeters I'm like ingenious. And then -- little not quite frequently take -- holt announced the signal down I've read a lot of books that excellent antennas work and basically the -- antennas. They keep telling me -- counting delegates willfully and she's and I understand it someday somebody didn't want to view what emailing -- explain to me how the the wireless energy it's out of the end -- I don't entirely understand them but I do know if you measure properly you'll get an antenna that works because you work in a quarter three quarter happily like. And that's we gallery here so."
" We won't let you next want this one's really -- this was really fun actually. -- just."
" Our Netflix ultimately -- the wake of the astronaut Barbara Starr mister Billy Bob Thornton I didn't government this is able to call this a touching saga. It's a hard act I -- that -- child kind of watch the deputy mostly just near the black blobby thing but he's -- definitely appreciate cinema but if you like. Building things if you like space if you like the idea of an individual and a Texan no less try something against the forces of government that would impress his desire to go into space you're gonna enjoy this like -- they're building this explosion this hospital seems cattle that rock -- aren't. Shot and critically that part out if you want it movies just like this or any of but not -- thousand -- liberty your doorstep you should check out Netflix. They got an amazing collection Blu-ray titles but I -- fans out there and with -- over already shipping centers across the country almost. Every delivery happens in a single business day Netflix plans start report dollar that sense it doesn't remember you can get -- two week free trial membership. Check it out at www. Netflix dot com slash system. Help us help you by supporting our sponsors and you can a movie we're gonna hang out the form her talk about the movies well it's -- to -- it. The problem."
" Can I say this and then it was fun to kind of is it's really fun Mac."
" Because essentially we're we're using for the ground -- on this one easy sorting can't. If you like sarbanes or anchovies is a wonderful opportunity for you can buy it. I have a T shirt right now and it's soaking -- because it was covered with -- soil which makes -- smallest opening cat when he. I can cast breakfast which really made me unpopular in the offices afternoon and also like to say that while this is a really -- antenna because it's a really slick way to create. You know it's like a twelve to fourteen point warped and now works out TV guide. Directional antenna which you really think you get something like a moment I can't."
" This which is a parabolic all of somebody's old satellite system that's going out of business have been replaced. And if you mount this here in used to parabolic -- 12730. Media and and it worked pretty well. And that's really cheap because chances are you've -- one of these don't want in the garage. Whose antenna designs from us you know wireless and these -- by water both time. And basically these are quarter wave points for two millimeter links. Copper wire fabulous. -- Housework. And the downside this antenna this antenna will drive you nuts. Every example of this antenna to -- on the web. Everything is like so nicely depending on who's doing measure me 3232 millimeters from what a particular people for years when when they're going for. Everything's perfectly square -- almost like was rendered in 3-D. -- of course -- of your six year old me but still actually works fairly well. It's gonna take a little bit of practice it and she if you want and I actually haven't you one more solder connection. From the backside in this and my reflector. -- You know it's the same fabulous technique from using before. For the last. Marty it's cooling your antenna. And so I'm wire here."
" Now what I'm told he."
" do this is if you measure tour put four millimeters. "
" And we're of course gonna need a little bit extra on the end there because we're gonna basically stand this hovering over eighteen millimeters. They're already used to stand this fifteen to eighteen depending on who you're. Asking me often recommend that you. Play with the distance between the reflector and indeed -- quad. Just for fun leave ourselves an extra twenty millimeters on there. Is nice to have little bit actual -- Remains -- 120 millimeters on this we're dependent in half at a ninety degree angle. -- yeah I can do geometry."
" Or -- myself this thing. In any case you some favour don't take the measurements for start this if here. Playing around with multiple antenna designers. Checked to make sure everybody's measuring the quarter wave -- in the same way. I know informed people are going to be like this or quarterly blink his but it. If you're looking at intends lines often see people rounding up and really interesting ways. It'll be really interesting if I measured the -- bit differently from the other -- see which one works more."
" I do recommend this let me show you how we can stop. The earlier one."
" Yeah -- yeah. Yeah. Yeah yeah yeah yeah."
" We want more -- soldering on this before we tested out and we want to remind you ladies and gentlemen and basically if you don't have an external. Antenna adapter on your car this isn't gonna work this is and then connector that people these antennas on -- of -- until these antennas on to you. -- connector screws on the back like this right. And it comes in view this case in this and B connector can also be something that looks like. -- guy that plugs directly into nor -- the -- But you're gonna need some kind of a pig tail that goes from here. Wi-Fi card external Wi-Fi or -- connectors on the back of many routers which we look a lot like. This actually. And your intent standard would -- on there very rare actually -- a more common. But it emotional really cute computer store nearby you probably have do you order the pig tail. It's a B connectors of the and connectors on the Internet more puts enough. Sources in the show notes and -- you can also identified it personal connector."
" these two guys off the wind surfers off -- Randolph Chelsea being solved his fly by covered in his house where they solved it in my old house. I'm gonna be playing around with the sixty be -- Linear. Later on we're gonna be clear on this poppy we'll talk about that another time right now -- I -- next week. David Randolph going to be back with a representative from universal laser talking about some of the inside tricks some of the may have you can get into a laser -- this should be ridiculous because I've already seen what dvd you would coaching from an engineer inside -- which is everything from. Custom decorated your -- to notebooks too I think -- may have been one personal tattoo on game crater although that is unconfirmed at this time if he's Amsterdam perhaps working off after effects of the laser etching. I'm having Norton this assistant hope you had fun with this went. These all work build them. We'll see you next week."

Everything is like so nicely depending on who's doing measure me 3232 millimeters from what a particular people for years when when they're going for.

Just for fun leave ourselves an extra twenty millimeters on there. Is nice to have little bit actual -- Remains -- 120 millimeters on this we're dependent in half at a ninety degree angle. -- yeah I can do geometry."
" Or -- myself this thing. In any case you some favour don't take the measurements for start this if here. Playing around with multiple antenna designers. Checked to make sure everybody's measuring the quarter wave -- in the same way. I know informed people are going to be like this or quarterly blink his but it. If you're looking at intends lines often see people rounding up and really interesting ways. It'll be really interesting if I measured the -- bit differently from the other -- see which one works more."
