The antenna-gun resembles the appearance of a space blaster and, just like this fantastic weapon, has a directional and very powerful effect.
This is a directional antenna. And it is this property that gives a long reception distance due to the high concentration of the signal in one direction.
Antenna diagram
The drawing shows the dimensions between the antenna elements. Its resonant frequency is set to the middle of the Wi-Fi frequency of 2.4 GHz.
To make an antenna you will need
- Long stud with nuts.
- Metal sheet, I took copper because it is very easy to cut. In general, you can take tin from cans.
- Wi-Fi Adapter. But you can connect to an existing router.
Making a powerful Wi-Fi gun antenna
Before you start making an antenna, you need to know that any deviation from the specified dimensions will greatly deteriorate its performance. Therefore, everything needs to be done as accurately as possible.
We take a sheet of metal and roughly mark the centers of the diameters of the circles. Then we drill the center.For accuracy, before drilling, place a core or go through a thin drill, and then a thick one. As a result, the diameter of the hole should be slightly larger than the stud.
Then we take a compass and draw circles on the metal.
First cut out a square.
Then carefully cut out a circle.
The result was circles for the antenna.
I took a long hairpin. I cut off the excess along the length of the antenna, taking into account the width of the nut.
Here is the finished kit for assembly.
We assemble the antenna. Everything is very simple, like a construction set in childhood.
To control dimensions, I recommend using a metal ruler, as it is more accurate.
In the last two disks you need to make holes for connecting the cable.
We will make a connector with a cable from an old antenna from a router or adapter.
Remove the top casing.
Cut off the insulation. The antenna came off on its own because it was pressed in.
Next, unsolder the metal cap.
And the connector for connection is ready.
We tin the wheels. Copper is great in this regard. I once made such an antenna from an old computer case, so I had to tin it with acid.
We pass the cable through the hole in the last circle and solder the shielding winding to the disk.
Now we pass the middle core into the hole of the second disk and solder it.
The antenna is almost ready. I will install it on the camera bracket. There will be such a home option.
Screw it to the connector output Wi-Fi adapter.
You can tape it with electrical tape or tape to the bracket.
I will put the antenna on the window and point it at objects where there may be a signal.
Wow, how many networks have appeared. Although previously I only caught a signal from my router. There are not many access points in our city.
The result is amazing.
Add-ons
To enhance the effect, I decided to install such a cannon on the roof. But to do this, I need to solder a regular shielded cable, which I use for a satellite dish, instead of a connector.
Let's drill the hole a little and modify the cable plug.
We fix it with electrical tape.
We put it on the roof, placing it on a pole.
The number of networks exceeded all my expectations.
Result
The result was that a single type of antenna can be used to communicate over a distance of about 10 kilometers without any problems! And this is without any amplifiers or special equipment.
With the help of such a powerful Wi-Fi gun - antenna, you can transmit a signal to the garage, work, school, or country house. All materials are available to absolutely everyone, and everything is done very simply.
Watch the video
More detailed assembly instructions can be found by watching the video below. It also shows more extensive testing of this powerful Wi-Fi antenna.
PS: If you are making an outdoor version, then for insulation and against corrosion it would be a good idea to paint the entire antenna with regular metal paint.
