Making a GSM Booster With Two Tin Cans

You may have several reasons for poor GSM signal — rural location, thick walls, dead mobile zones, etc. Whatever the reason is, the result is always the same missed calls, awful audibility, stress and irritation. However, you can get rid of poor GSM connection with the help of a self-made GSM booster.

Before starting the construction process, turn off your mobile device. Now let’s get down to the tin cans. 

Make an open cylinder of one can — just remove its bottom.

Then join the two cans together to make one long empty can. Make sure that there are no open spaces between the two cans, use copper tape. It’s important to connect the cans as tightly as possible to get the desired result.

Now measure 97 mm from the can bottom and cut out a small hole for the antenna.

The next step is making the antenna itself. You will need a small piece of copper wire of corresponding length and thickness. This wire should be first soldered to the antenna connector and then placed inside the can through the hole you’ve made previously. Use the nut that comes with the antenna connector to secure the construction.

Now you need to connect a pigtail that works with your device model. Put in one end of this cable to the antenna connector on the self-made repeater.

The other end should be plugged into your mobile device.

As a rule, phones have this special output for the antenna. If you have some difficulties finding it, just get in touch with your manufacturer and clarify where the needed antenna port is. 

Finally, turn on your mobile device. Keep the open part of the self-made cylindrical repeater in the direction of the nearest base station. Try to make a call and check the quality of the connection. If you’ve done everything correctly, the audibility will be better.

We draw your attention to the fact that this self-made booster can’t completely solve signal issues around large areas, they may only refine connection for the particular phone.
