DIY 3G signal booster

Not always 3G modems provide us with stable and high speed Internet. To amplify the signal, you can purchase a special antenna and spend several thousand rubles, or you can make it yourself by spending 2 hours of your time.

In order to manufacture a 3G signal amplifier do it yourself watch this video



To create a 3G signal amplifier, we need:
- a board twenty twenty 75 centimeters long;
- a piece of galvanized iron 75 centimeters long;
- screws;
- copper tube six, thin-walled;
- a pipe from a sewer pipe;
- insulating tape;
- television cable 75 waves;
- soldering iron;
- exhaust rivets;
- metal corners;
- pipe 25;
- 3G modem with a jack for connecting an external antenna;
- adapter for connecting an external antenna;
- cable.

1. A piece of galvanized iron is screwed to the board with screws.

2. For the manufacture of the antenna we need a copper tube, it is advisable to purchase a thin-walled, as it will be easier to bend. You can bend according to the pattern.

3. The side of one rhombus is approximately 5.2 - 5.3 centimeters.

4. Each side must be bent into four diamonds, in the middle of the tube should not touch.

5. This is how our antenna should look like, four rhombuses in one direction and four rhombuses in the other direction.

6. As you can see, in the middle of the tube they do not touch each other, the distance between them is 1.2 centimeters.

7. You can mount the antenna on the pipe from the sewer pipe.

8. The distance from the screen to the antenna is approximately 3.5 centimeters, and on the other hand the antenna should be at the same distance.

9. To insert the antenna, make slots in the tube.

10. And we attach the tube to the corner.

11. When we make the antenna, we wrap the tubes in places where they are connected by an insulating tape so that they do not touch each other.

12. In the board we make a small hole for the television cable.

13. We pass the cable, solder the central wire to the upper tube.

14. Solder the wire from the sheathing to the lower tube, isolate it with insulating tape.
15. On the plank itself, two corners should be screwed onto the pipe twenty-five.

16. On the corners themselves we make holes.

17.Then on the pipe itself we will make the same holes and tighten with rivets.

18. The antenna is mounted on the roof, connected by cable to a 3G modem, communication is increased several times.

Thanks to all sorts of stray, including Chinese-made, no signal power is increased!
Oddly enough, but the signal reception becomes simply more stable, uninterrupted (turned down!) Or something, and due to this, it seems to us that the Internet is working faster ...
Dear "residents of our site," I also use your work. I want to complement your collection with my design of an Internet signal amplifier. It will be clear from the description. The amplifier is made on a grandmother's lamp. For the concentration of thermal radiation, the lamp has a reflector, inside of which there is a cartridge for an electric lamp. What are we doing? We remove the lamp and the contents of the cartridge. In the empty cartridge we make a hole for the cable with the USB connector, into which we insert the modem. It is necessary to try so that the SIM card is located so in the cartridge as the hair of the incandescent lamp was located. We insert the other end of the wire into the computer. We direct the reflector towards the city (I was on the garden plot), i.e. to the tower. We insert the other end of the wire into the computer, etc.
Although not, I'm lying .... Well, I went to the same place !!! .... AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
I like Dmitry's version (about interference) more like it)))). Because my short one is also good, of the same quality. It would seem that it should be better .... but it is worse)))))
Sorry ... but what's the point of self-scorching the wire?)))) .... Not ... well, I'm also a master .... but, damn it ... not to the same extent! )))))))))) Extenders are even used to buy on the way home, so as not to look for the one that certainly is at home ...))) That’s a penny ...
Most likely, on a bad cable, more time is spent on interrogating and re-sending the missing information. It seems to me. :)
neither 3G nor 2G works directly from my USB. I made a self-made wire 2 meters, it catches everything perfectly at any point, even under the table.
And on a computer nichrome. Most likely the computer creates interference, the amplification has nothing to do with it. IMHO
And I once experimentally, quite by accident noticed that if the “trijik” (YUSB 3ji modem)))) plug in a GOOD extension cord, then the signal is amplified a bit, even if the “trijik” is not carried anywhere. That is, in some incomprehensible way, the cable itself acts as a ..... antenna, or something ... I don’t know how it is possible - it is AFTER the modem, but it was really noticeable! (I have a five-meter extension cord with gold contacts). Connecting directly, or through a short one and putting it in the same place, the Internet was not sustainable. And through it - op-p-pa is ....
And how much time did you spend reading to become? This is a 3G signal amplifier and not Wi-Fi :)
With all due respect to the Author, I want to assure you - such antennas do not give a positive result. This is "Sisyphus labor." And simply - a waste of time and effort. No matter how the author assures you that this device does not work, it is "disingenuous". Do not waste time, because I myself have already learned from my mistakes, because I spent a lot of time and energy on solving this problem to no avail, because You can amplify the WiFi signal only on the transmitter, but not on the receiver. It all depends on the signal strength and the distance between the receiver and the transmitter.
They are very cool specialists: that "lena30011988", that the author of the video, whose cable sheath is called either "winding", then "sheathing". Electronics, you see, was taught "not from textbooks," as the old song says.
This is all right ... It is clear that I was mistaken ... 75 Ohm. But once, when there were no cellular ones, they asked me to wind a wire resistor 100 meters through an intermediary ... (????). I ask, what section of wire is he interested in? Why 100 meters? Usually resistance is important, not the length of the wire! .... They answer me: "No, he asked for exactly 100 meters, but he didn’t talk about resistance .....
It turned out that he wrote to him on a piece of paper: "Ask him, let him wrap a 10 Ohm wire resistor" ... 10 Ohm !!!!! )))))))))))))
"cable 75 waves" - how is it? ;)
