You have probably arrived at this page because you are looking for a range extender antenna for your WiFi system. We have written this article.How To Make A Tin Can Directional Wi. Fi Antenna to Extend your Communication after an EMPEditor’s Note: After an EMP or CME (Corronal Mass Ejection) the world will go dark and silent. However, if you have your faraday cage ready and packed with all essential electronics, together with a solar generator to power your PC or your phone, you’ll be one of the very few people who’ll enjoy a strong tactical (communication) advantage. You might be inclined to say that a Wi. Fi antenna will be useless in the aftermath of an EMP, but remember that the Wi. Fi is simply a radio, which is used for computers or smart phones. Another spec of Wi. Fi is that its waves have a short range, however, today’s article will show you how to increase your Wi. Fi antenna’s spectrum. So, be one step ahead of everyone when the world as we know it will be gone. Looking for an inexpensive way to increase the range of your wireless network? A tin can waveguide antenna, or Cantenna, may be just the ticket. This design can be built for under $5 U. S. Also, here’s the ten cent modification you can do to double your radio’s range. I am not an electrical engineer, nor do I have access to any fancy test equipment. I’ve built some antennas that worked for me and thought I would share what I learned. I have no idea if this is safe for your radio or wireless network equipment. The risk to you and your equipment is yours. Building your Cantenna is easy, just follow these steps. Collect the parts. Drill or punch holes in your can to mount the probe. Assemble the probe and mount in can. Collect the parts: You’ll need: A N- Female chassis mount connector. Four small nuts and bolts. A bit of thick wire. A can. The Connector. A N type Female Chassis- mount connector. One side is N- female for connecting the cable from your wireless equipment, and the other side has a small brass stub for soldering on wire. These can be found at electronics stores internet suppliers (see the list below under “Connect your antenna. I’ve used #6. If your N- connector is a screw on type, then you won’t need the nuts and bolts. Wire. You’ll need about 1. ![]() ![]() This wire will stick into the brass stub in the N- connector. A Can. This is the fun part. You’re looking for a can between about 3. The size doesn’t have to be exact. I made a good antenna with a Nalley’s “Big Chunk” Beef Stew can that was 3. Others have reported good results with big 3. The Pringles can is really too small for good performance, however. Try to get as long a can as possible. The old fashioned fruit juice cans should work well. Drill or punch holes in your can to mount the probe. The N- connector assembly will mount in the side of your can. You need to put holes in the right place to mount the connector. The placement of the hole and connect is very important. ![]() It’s location is derived from formulas that use the frequency that the antenna will operate at and the can diameter. To make life easy on you, here’s a calculator to figure it out for you. Can Diameter 8. 02. Wi. Fi networking equipment operates at a range of frequencies from 2. GHz to 2. 4. 62 GHz. Ideally, with your can size, the TE1. TM0. 1 cut- off should be higher than 2. It would be good, also, if your can is longer than the 3/4 Guide Wavelength. If your can is a little off in length or diameter, don’t despair, experimentation is fun! You want to mark the location on the can where you will put the hole for the connector. The 1/4 Guide Wavelength number tells you how far up from the bottom metal end of the can to put the center of the hole. Open only one end of your can, eat the contents, and give it a good washing. ![]() Unlock your Phone. Intro: UPDATED!!!! Cheap and Easy WIFI Antenna Signal Booster That Is Better and Quicker Than the Paper Ones!!! A new swing on an old idea for improving your WIFI. Omni-Directional Antennas Applications, Radiation Patterns & Range. Bigger is not always better: Optimal choice of dipole antenna is determined by the relative. Turns out, there's a right and wrong way to set up a WiFi. You’ll probably want to remove the label too. Use a ruler to measure up from the closed end 1/4 Guide Wavelength and mark the can with a dot. If you’ve got a drill, select a bit that matches the size of the center of your connector. You may want to start with a small bit and work the hole larger and larger. You could even start with a hammer and nail, then use drill bits. If you don’t have a drill, start with a nail hole and use a file to get the hole to the required size. If you’re using a bolt on connector, make four more holes for the bolts – you can use the connector as a drilling guide. ![]() ![]() How to Make a Wifi Antenna. Have you lost your WiFi antenna? Most antennas can be removed from WiFi cards, making them easy to lose. With a few household supplies. GSM & GPS Antenna We are engaged in supplying wide range of GSM / GPS Antenna.Under this catagory we offer 2.4G Soft Antenna (IPEX Connector) WiFi Antenna, 2DB Gain. Assemble the probe and mount in can. Now you’ll need that bit of wire. You’ll need a soldering iron or a friend with one as well. Cut the wire so that when it is stuck in the connector as shown, the total length of both the brass tube and wire sticking out past the connector is 1. Get as close to this length as you can. When you’ve got your wire correctly sized, solder it into the connector keeping it as straight and upright as you can. When it’s cooled, bolt or screw the assembly into your can. Put the heads of the bolts inside the can and the nuts on the outside to minimize the obstructions in your antenna. Your Done! Connect your antenna to your wireless card or access point. To use your cantenna, you’ll need a special cable commonly called a “Pig Tail”. Shop for Wifi audio receiver at Best Buy. Find low everyday prices and buy online for delivery or in-store pick-up. USA.com provides easy to find states, metro areas, counties, cities, zip codes, and area codes information, including population, races, income, housing, school. RadioLabs WiFi Antenna Cable Coaxial cable is one of the most important, and often overlooked aspects of any wifi installation. Coax is literally the lifeline of your. The pig tail connects your wireless card or access point to you antenna. One end of the cable will have a “N” Male connector (just right for connecting your your cantenna), while the other end will have a connector appropriate to your card or access point. You’ll want to have a wireless NIC or access point with an external antenna connector. Otherwise, you may have to hack into the one you have to hook up the cable. I wouldn’t recommend this unless you’re good with a soldering iron and electronics. For this reason, I like the Agere Orinoco cards which have a nice antenna connector. Pig Tails can be hand made if you have the right tools, but it’s probably easier to get a pre- made one. Try: Fleeman Anderson & Bird. Fleeman Anderson & Bird has a “cantenna kit” for sale that includes the connector and pigtail. Choose one of the “cables” links from the menu and look towards the bottom of the list. Hyperlinktech. Antenna Systems. Hook up your cable, point the antenna at a friend’s, and see how far you can stretch you network. This antenna has linear polarization. That means that how you rotate the antenna will affect the strength of your signal. Usually, you will want to put the connection straight down, but experiment with rotating the can while watching the signal strength on your PC to get the best performance.

Fig. 1 Large (7. 6cm) dish with a biquad antenna. A satellite dish is a powerfull signal booster when used in combination with a Wi. Fi biquad antenna. I see lots of satellite dishes laying in trash when driving. Grab one next time you see an old dish laying on the sidewalk. I have tried using both smaller Dish Net dishes and larger 7. The larger dish will give you some extra gain but even the small one works really well. How far you can go with this booster? I have tested it up to 2. Netgear router on the other end and it worked flawlessly. The router was using the stock antenna it came with. First disconnect the so called LNBF from the dish . Then mount your biquad antenna in place of the LNBF. Ideally, it should be in the exact same position as this is the focal point of the parabolic dish. Fig. 2 Dish 5. 00 and LNBFFig. Unprotected biquad antenna will corrode outdoors. Fig. 4 This antenna was housed inside an enclosure and it did not corrode. You can mount the “naked” biquad . I tried mounting the antenna directly to the arm of the dish . In addition, an exposed antenna can be easily damaged should the dish lose footing. A better way is to house the antenna in an enclosure and mount it using a support made of PVC electrical conduit pieces . Dish Net dishes have a chunky LNBF that sits up high. Anything you can do to lift the position of your antenna and make it close to where LNBF sits will help. Fig. 5 Mounting biquad antenna on Dish 5. Make a provision to rotate the antenna 9. The ability to rotate 9. Fig. 6 Biquad antenna polarization. Fig. 7 Dish 5. 00 fitted with Wi. Fi antenna looking down. All satellite dishes are designed to point up to the sky. Even when the dish is seemingly 9. To properly aim the beam you will need to point the dish down . Using a free tool like Netstumbler is a good way to aim your dish properly. Once you lock the maximum signal tighten the screws on the dish and rotate the antenna 9. One of the two polarization positions will give you stronger reception. Securing the dish with bricks like I’m doing in this picture is a very bad idea. Winds can easily knock the dish down or lift it off your roof. Use something heavy to hold the dish down while locating a good spot to place it. Once you find the spot mount the dish permanently with heavy screws. Keep in mind that RF cable attenuates high frequency signal a lot. Keep the cable run at the absolute minimum or else all the signal gain of the antenna will be devoured by the cable. If you don’t have a proper Wi. Fi directional antenna, you could try mounting a USB wireless adapter on the dish instead. Finally, there may be regulations determining maximum signal strength for 2. GHz frequency in your country. In the United States FCC regulates such matters. It is not likely that FCC would take any action unless they receive interference complaints from people or business in your signal path. Also, this setup is fairly limited and without powerfull amplification you will probably not bother anyone.
