Amplificador señal móvil casero ¿Cómo construirlo y qué debes tener en cuenta?

Making a homemade mobile signal booster is an idea that crosses the minds of many people with mobile signal problems. It is common for telephone companies to not offer an effective solution to the connection problem. And that is why, as users, we look for other alternatives.

If you don’t have a lot of money to invest, making a homemade mobile amplifier is the best option. Keep in mind that the ideas we will tell you are a compilation of what you can find on the Internet.

We will also tell you what you should take into account to solve your mobile connection problems.


Ideas to build your homemade mobile signal amplifier

Making homemade antennas to improve the signal will require: time, effort and obtaining the right materials. Of course, how these “experiments” work is debatable, but they are worth knowing.

The magic wire

This idea is very common to hear. The theory of its functionality is based on the conductivity of materials to receive and improve electromagnetic waves.

To apply this idea you will need:

  • 40 cm of iron wire
  • 2 connection blocks
  • 1 small nut
  • 1 small bolt
  • 10 meters of coaxial cable
  • 1 piece of hookah
  • Plastic jar.
  • pliers

Take the pliers and straighten the wire, until it is bent in the center at 90 degrees. Form a square with the wire with 8 centimeters on each side. Then, leave the two ends open to install a connection block. Then tighten it with a screwdriver. Finally, the hookah, bolt, nut, and coaxial cable come into play.

Be careful when handling these materials. Working with bare wires is dangerous.

The miraculous aluminum

Aluminum is a material that is used to solve everyday problems. It is so useful that it has also been used to experiment in making homemade mobile signal antennas.

To carry out this idea, you will need several materials.

  • 2 aluminum rods of 30 centimeters
  • 2 rods of 15 centimeters.
  • A good adhesive tape that guarantees a secure fit.
  • 1 rule.
  • A screwdriver
  • Standard cable (available at most hardware stores)

You can see the complete procedure at the following link:

a clip

This alternative is based on the concept that every wireless device has an integrated antenna. This element has the task of providing mobile coverage. Therefore, the idea is based on using a metal element (clip) that will serve as an extension of said antenna. Thanks to the “homemade” extension of the antenna, greater mobile coverage will be achieved.

To do this, straighten a clip hook and tape one end to the cell phone antenna. As you can see, this is the simplest idea you will find on the Internet. Surely, you have nothing to lose by trying. It seems simple and you only have to invest in a paper clip and the tape. The only thing you should keep in mind is the risk you run by damaging the original antenna that the cell phone has built in.

Also, you should imagine how “comfortable” and “aesthetic” it must be to carry a cell phone with a homemade antenna in your pocket.


So…Is it no use building a homemade mobile signal booster?

We know we all try to do what we can if it comes to saving money. However, the chances of any of the homemade ideas working are low. And although they probably generate a small improvement, we know that they can also become a nuisance when using your mobile.

Advantages and disadvantages of a homemade mobile signal booster:


  • You will invest much less money than buying devices already certified to amplify the mobile signal.
  • If you build it to the letter, you may find that the signal is a little better than what you already have.
  • You know a little more about the technical operation of mobile phones and signal antennas.

Disadvantages of a homemade mobile signal booster:

  • If they don’t work, you will have lost some money.
  • The final product of homemade antennas is not aesthetic at all. You will have tape everywhere, slightly twisted wires, etc.
  • Homemade antennas are difficult to transport due to their very fragility.
  • Being a homemade product, the finished product is not of quality. Therefore, the durability will not be the same compared to a factory mobile signal booster.
  • The probability that it will actually work is very low.
  • If you are not good at crafts, you risk damaging the mobile phone.

And what about mobile applications? Are they a better solution?

In the app store you will find dozens of apps that claim to improve your mobile signal. But how true is it?

These apps work by searching for the closest telephone network or the one that is providing us with the best signal quality. By doing this scan, you can strengthen the connection of your mobile phone. In conclusion, it disconnects from the current telephone base station to find a better connection. Of all the ideas raised, this is the one that seems most effective.

But it is necessary to see the other part of the story. The reality is that the poor mobile coverage is mainly due to two factors.

The first is that you are located in an area far from the cell tower. The second is that you have a tower nearby but the obstacles between you and the tower interfere with the quality of the signal. Whether walls, buildings, houses, among others. Therefore, the apps have two small drawbacks. The thing is, it is very unlikely that there are other telephone towers with a better position to emit the signal to us. Furthermore, if the application remains active evaluating the signal it receives, the mobile battery consumption will be greater.

Users who have invested in paid applications, these are not the best solution either.

Homemade Mobile Signal Booster vs Certified Amplifier

If you have come this far, it is because you surely no longer tolerate having a bad connection on your cell phone. But, if you want a definitive solution, avoid investing your money in homemade ideas that do not offer a guarantee.

Indeed, a mobile signal booster is the device you need to improve your mobile coverage. However, when you are looking for quality and guarantee you must be aware that you need to invest a little more money.

A certified mobile signal booster on average can cost you between 200 to 1500 euros. Of course, we are talking about guaranteed, certified devices with good comments from customers.

¿Cómo funciona un Amplificador de Señal Móvil Certificado?

Su eficacia radica en los conceptos técnicos básicos de las redes de comunicación. La mejora de la cobertura móvil se logra mediante una antena exterior, un amplificador de señal y una antena interior.

La antena exterior se ubica en la zona externa donde logres recibir la mayor cobertura móvil posible. Allí su función será recoger las señales débiles que recibe de la torre de telefonía más cercana. A su vez, esta antena se conecta con el equipo amplificador que se encargará de potenciar esa señal que recibe. Para luego, emitirla a través de la antena interna en la zona donde necesites mejorar tu cobertura móvil.

Esta es la mejor manera de obtener una excelente cobertura móvil instantáneamente.

¿Cuál es el mejor amplificador de señal móvil?

All amplifiers work under the same system, so they will all be equally effective. The important thing is that you choose the one that truly fits your needs. We have a wide offer depending on the signals you want to improve. We have amplifiers to boost your voice signal, 3G or 4G , or if you wish, for all bands in Spain.
