![]() ![]() Whether you are using a homemade cell phone signal booster or a commercial one, battery power can drain more quickly. Try to keep your cell phone charged all the time as a weak battery generally cannot pick up cell signals. Allow the wire to stay while replacing the back. Run the wire to the top of the phone and extend it like an antenna. ![]() Now, bend the wire over and tape it on the back of the phone. Without including this wire, carefully cut the wire to a 6.3-inch length( one-fourth of a wavelength). Next, using an insulated magnet wire, remove a small piece of insulation( half an inch) from one end using a nail file or sandpaper and insert the stripped end into the antenna port. To make this signal booster, slide the back off of your cell phone and access the internal antenna port. Tape the wrapped end to secure it in place. This will extend the antenna thereby increasing signal strength and stability. This works great for cell phones having an antenna stub.Īll you need to do is wrap the twist tie around the lower end of the stub a couple of times, leaving an inch or two of length protruding beyond the end of the stub. Using twist ties is a simple and effective way to boost your cell phone’s signal. You should be able to see an increase of one or two bars in signal strength. Use a metal spring clamp to clip the end. Next, plug your cell phone into the USB charger and wrap the cord around the metal tube. Simply tape one end near the top of your phone such that the tube extends upwards from the phone. Mini external antennaĪnother way is to use any slim metal tube like a pen or drinking straw (metal) to form an antenna. Remember to aim the open end of the can in any direction till you get a strong signal to make a call. Make sure that the other end of the pigtail connector fits your phone’s charging port. Plug the other end of the wire on the pigtail connector onto the end of the antenna connector into your phone’s antenna port. Now that the antenna array is complete on the inside, tighten the pigtail connector onto the end of the antenna connector that remains outside of the can. If the hole is too large, you may need to add washers to complete this part. ![]() Place the nut on the shoulders of the antenna connector from inside and tighten it. Push the antenna connector with copper wire attached through the hole on the outside of the can just till the shoulder of the antenna connector reaches the inside of the can. Next, solder the copper wiring instead of taping with masking or duct tape as it will dampen the effect. ![]() Take a 3-inch length of copper wire and attach it to the antenna connector by pushing it firmly into the end. Measure the neck of the antenna connector to know how large the hole needs to be. Next, use a knife to cut a round hole 3.75 inches up the side from the closed bottom. Alternatively, you may choose to use adhesive-backed copper tape, overlapping the joint between the two, and seal the tape to the metal on either side, firmly. Before adding the solder, apply heat to the area to be soldered with the tip of the gun. Heat a soldering gun and carefully solder the open ends of both the cans together to form one tall can.
