Diy usb wifi yagi antenna

When we take a new Wi-Fi router from its box, the stock antenna is a short plastic stub with a reverse SMA plug on one end. More recent and more fancy Designing and building a Yagi antenna for 2. It is a highly directional antenna that allows you to connect to your WiFi router from much farther away than normal.

Overall, this 2. Many of the Internet articles are written by new computer hobbyists WiFi that know very little about RF!! Build Yagi Antenna Wifi Diy - dpokmesh trend dpokmesh. Step 2: Building Overview. Step 3: Printing the Yagi Diagram. Step 5: Building the Backbone.

Step 6: Building the Driven Element. Step 7: Connect the Antenna to the Wifi Modem. In a previous IoTuesday post, I gave examples of makeshift antennas you could build at home. Achieve faster downloads and lightning speed internet connection with our USA made long-range high-gain WiFi antenna.

This wifi antenna will allow for long range wireless networking on 2. The Wifi antenna that the creator made in this video tutorial guide works at a frequency of 2. Why this design was chosen is because it has a consistent element length, has a gain of more than 5db, and the materials used ate super durable. This article describes the phases for the construction of a Yagi antenna. The calculations of the parameters are made using 4NEC2 software.

This type of antenna is used for transmissions and receptions of electromagnetic waves. The project shown here refers to the frequency of Now I'm using this antenna more than 6 months. BiQuad antenna is a Omni Directional antenna.

But has lower gain compared to Yagi Antenna. I made a yagi antenna too. The more directors on the antenna, the more directional the beam, which results in higher gain. Making your own Yagi-Uda can be done very cheaply and requires only a few common tools.

Easy to build wifi 2. First disconnect the so call. First, connect the usb wifi adapter and usb extension cable. For tips on how to fine tune the antenna once you're connected, scroll down!

Speed test Glossary of Satellite TermsYour browser indicates if you've visited this link Depending on their use and operating frequency, antennas can take the form of a single piece of wire, a di-pole a grid such as a yagi array, a horn How do TV detector vans work?

In this video, I will show you how to construct a dual-band long-range repeater for 2. In this Instructable, I make a battery-powered portable long-range 2. It can also be used to find open WiFi access points on the go. It is working pretty well. Just the range is a bit short. I found a solution to this problem. This mode is much more low level. Do you want to boost your WIFI? Looking for a DIY antenna? You can build your own WIFI antenna by having a look at this tutorial.

In this video, we learn to make a powerful WiFi antenna for a long-range signal catcher. Home Made 2. It works great too. I wanna show you how to make 1km range wifi antenna at home easy way. You can see my another log range Wifi antenna video from CAD or end screen. The performance was pretty spectacular for this easy to build antenna.

I was able to see the WiFi of a hotel that was 2 miles away from my home. The most difficult part was connecting the antenna to the USB modem. Okay well I read through the entire post and I saw many things that made a lot of sense, also saw a lot of unnecessary flaming, but I do have a few comments to make.

Right off the bat the one individual that asked about having his modem in the basement with a rotating antenna on the roof needs a reality check. Take the dongle apart and connect a USB extension cable to it and mount it directly on the antenna assembly.

Paper clips vs copper, at this frequency it's not going to make much difference, however the specific model was generated using 14awg copper. Someone said glue it all to cardboard then cover it with more cardboard actually a strong and stable design, original author said build around popsicle sticks wooden , both are subject to absorbing moisture from the air and either can have a poor dielectric constant, I would suggest some kind of plastic they make popsicles with plastic sticks.

The lengths of the elements, the spacing between them, and keeping them all in the same plane and parallel to each other is the most important consideration.

If you use the folded dipole make sure the folded part is perpendicular to the plane of the rest of the antenna and use ohm twin lead to connect to the dongle, but your SWR will probably be much higher, reducing your effective gain and possibly resulting in early failure of the dongle. Horizontal vs vertical, after you have your antenna connected and have connected to some network you can try rotating it about its horizontal axis to see if you can get a better aspect on the other antenna more bars.

All in all though good job to Biotele, it's cheap, it's easy, and if done right will provide excellent results. I did not build this antenna, but I built 2 antennae very similar before reading this post, My son and I live almost 2 miles apart and either of us can stream p movies from the other's house during a thunderstorm.

Reply 1 year ago. Was the setup with your son line of sight, or was there any foliage between you? Was this able to extend the original wifi network to the second location? Reply 6 years ago on Introduction. Reply 7 years ago on Introduction. Thanks upon this project.

For my recommendation, I would advise you to use a usb to Ethernet adapter then feed your router with Ethernet as usual. I'm a ham radio operator and have build many yagi antennas and am going to build this one.

Here's a suggestion. Then you do not need to print out the guide. Also realize there are factors outside your control so getting accuracy to about 1 mm is good enough for element spacing and length.

If you aren't that accurate, it will just decrease the gain some, but the antenna will still work much better than an omnidirectional one. Question 1 year ago. I still dont get where to put the wires on the natena I have USB wifi with external port for antena, I have the coaxial cable Bit did not see ani diagram where to solder them on the antena..

May be I miss something because of poor english, so please someone to help with a simple diagram on Paint. PS This looks exactly like an oldschool external TV antena. If I use one wouldnt be better?! Question 1 year ago on Step 4. Question 2 years ago on Step 2. As others have pointed out, the impedance matching is done poorly and not even explained properly.

I have added a picture of a matched element that also acts as an impedance transformer. The 2. That means you use a 2in wire, solder the center of the coax to its center, then fold one leg in half and solder it to the shielding.

See image. This is why those internal laptop antennas out of stamped metal have that shape. It's the quarter-wave hoof. Reply 2 years ago. Assuming your laptop is less than 20 years old, it will have USB ports which means you can follow the instructions as stated. Question 3 years ago. How the heck do you make precise cuts? I have a dial caliper that measures up to 6 inches, and gets down to the thousandth 0. I can convert your mm to inches, but I still can't seem to find a non-tedious way to cut a 14 guage piece of steel wire to precise measurements.

I want to know how non-precise you can be with these, because not even a million dollar company with the greatest factory can give accuracy to a theoretical set amount of millimeter cut.

Question 3 years ago on Step 3. I understand that skin effect is paramount to impedences and that if you increase the diameter of the driven element you can also increase the bandwidth and decrease the impedance to like 50 ohms and that a good measuring stick is your best friend in building these things as long as the math formula is good.

A tube within a tube allows you to adjust such lengths. Skin effect means tubes are better than wires which are heavier. BUT, where are the formulas for the driven lengths vs diameters and velocity factors of whatever cables?

Can someone please make a video with the instrucions in the comments, because its very difficult to follow. Can you give me a model of something acceptable?
