Homemade cell phone signal booster with two coffee cans | MyAmplifiers US

How to make a GSM booster with two coffee cans?

First, make sure that your phone is turned off - all actions can be performed only when the device is turned off. The first thing to do is to remove the bottom of one can to get an open cylinder. Make two cans together one by one to get the one long empty can. Connect the cans with copper tape so that there were no open spaces. The cans should be tightly connected - this is very important.


Next, it is necessary to measure 97 mm from the can bottom. Make a hole for the antenna there.

Now we need to make the antenna itself. To do this, take a small piece of copper wire, adjust its length and thickness, and solder to the antenna connector. This antenna should be inserted into the previously created hole so that the copper wire is inside the can. Secure it with a nut that comes with the antenna connector.


Now you need to connect a pigtail that is compatible with your phone model. One end of this cable is standard and must go to the antenna connector on the can. The other end plugs directly into your phone. Many phones have this hole for the antenna. If you haven’t found it, contact the manufacturer of the phone for further information about your specific antenna port.


Now turn on the phone. Aim the open side of the cylinder to the nearest base station and try to make a call. Chances are you will better hear your interlocutor now.
