8 Genius DIY Cell Phone Signal Boosters

Tired of having to stick your face in a corner of your living room just to use your phone because cellular reception is practically non-existent? Love hiking but can’t afford to stay disconnected while you’re chasing waterfalls and sunsets? If your answer is yes to either question, then a cell phone signal booster is just what you need.

The signal booster identifies and amplifies the nearest signal, improving the reception of the phone. But most cost $400 or more, which leaves you with a good way to cut costs. Here are eight genius DIY cell phone signal booster ideas for inspiration.

1. Cheap and simple GSM signal booster

You don’t need a big budget or complicated widgets to make a mobile phone booster. Just take whatever copper wire you have, a magnetic GSM antenna, then follow the step-by-step instructions illustrated in the video above to build your signal booster.

Result? A highly efficient booster for 2G, 3G, 4G to LTE mobile phone signals, so you never have to deal with call interruptions no matter where you are.

2. Homemade Mobile 4G LTE Signal Booster

Just need a 4G signal booster? Well, creating one isn’t rocket science. And you won’t need complicated items either. You will use easy-to-find items for the project, such as iron wire, a magnet to confirm that it is indeed iron wire, a screwdriver, a measuring scale, and a TV cable.


Start by straightening the rope, bending it 45 degrees, and following the YouTube step-by-step instructions above.

3. Iron Hanger Booster

Did you know that you can make a signal booster out of an iron? If not, now you do. And the process is quite simple.

Simply straighten the iron hanger, scrape its insulation with a razor blade, bend it to form a diamond, then complete the process as shown in the YouTube tutorial.

And if that doesn’t kill enough of your time, check out other simple DIY projects you can do to beat weekend boredom.

4. Cell phone signal booster using PCB

If you are fed up of lousy cell phone reception and have a knack for engineering projects, this PCB cell phone booster is perfect for you. It will take a little longer to complete than other projects on our list, but once you’re done, you’ll have a signal booster capable of amplifying 2G to 4G network signals.

No doubt it’s worth the effort, plus the tutorial is pretty simple and even includes links to more detailed tutorials, so you can easily create your tutorials . You can refer to how to solder wires and electronics to make this project easier.

5. Multi-purpose signal booster

Got a lot of cell phones that need a signal booster? Take this versatile signal booster and skip the cost of buying an expensive multi-signal repeater. For this project you will need copper coils, a transistor, a 30pf variable capacitor, a pair of 200k, 2.2K and 100ohm resistors, a 27pf capacitor, a 20MHz crystal oscillator, an LED to indicate when it’s working and a PCB board to put it all together.

The supplies won’t cost you much, plus it’s cheaper than commercial options. The best part? After you’ve made the copper coils (by winding them on a screwdriver), all you need to do is attach everything and your all-purpose signal booster will be ready to go.

6. Aluminum foil signal booster

Iron mount signal boosters are easy to make but what is even easier is aluminum foil signal boosters. All you need to do is wrap a piece of copper wire, fasten a 3.5mm RCA jack, stick one end to the wire in foil, and connect the end to the jack to your phone to boost the signal.

It’s simple to build and highly portable, meaning you can take it with you on your camping trips. Most importantly, it is highly effective because the aluminum foil focuses the signal towards your phone, which in turn increases signal range and performance. Besides boosting the signal, this easy-to-implement signal booster protects you from hackers as the foil focuses the signal in only one direction: your phone.

7. Homemade telephone antenna with copper cable

For this project, you’ll need to peel off half a meter of copper cable to remove the insulation and then use it to create a circuit, as shown in the video above. Once done, stick the circuit on a large enough piece of tape, make sure you also cover the other end with tape, attach it to the back of the phone and voila!

Now you’ve got a discreet cell phone signal booster that you can take with you wherever you go, so you’ll never have to complain about poor network and Wi-Fi signal again.

8. Cellular signal booster using box

If you’re still pondering your options, this could signal an accelerator might interest you. And it’s also one of the easiest to find. Just unscrew the bottom of your last soda can, cut out the body as shown in the video, put a piece of aluminum foil inside, then place your phone to boost the signal.

Again, it works because the foil pushes the signal towards your phone, which improves Wi-Fi and network signal strength.

Perks of DIY Cell Phone Signal Booster

Besides no dead zones, here are some other perks of boosting your own cell phone signal at home:

It cuts costs

Commercial boosters do a great job of eliminating dead zones but come with a hefty price tag. Most of them cost between $400 and $800, but making your own will cut costs considerably. In some cases, such as the canning technique and aluminum foil option above, it won’t cost you even a dime, but you’ll enjoy an improved signal.

Longer battery life

Nothing reduces your phone’s battery life faster than poor reception. When the signal is poor, your phone will try to compensate by amplifying the received signal. This only speeds up battery drain and affects your phone’s ability to hold a charge longer as you’ll need to recharge it frequently. DIY one of the easy DIY cell phone boosters above will help you get rid of this problem.

Create a cell phone signal booster today

As shown in most of the projects above, a cell phone signal booster is one of the simplest DIY projects you’ll ever make. You can opt for something as simple and portable as the four-minute phone signal booster antenna above, or if you’re up for a challenge, create one that uses a PCB. Whatever it takes to build your own boat, we hope you enjoy making these projects a reality.
