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.
