We are honored to help you “carefully select” the most suitable phone jammer for your needs among the first-class devices sold in our online store.

Due to the continuous development of wireless technology, it is everyone’s responsibility to use our professional equipment to help maintain silence in areas where quiet behavior is needed. What is a mobile phone jammer? Nowadays, mobile phones have had a huge impact on everyone on this planet. They are considered a large-scale and popular communication method used by over a billion people worldwide. The popularity of mobile phones and smartphones not only brings advantages, but also disadvantages for those who use these devices. That’s why we firmly believe that almost everyone should have a mobile phone jammer, which is an essential small tool in daily life.

The mobile phone jammer is essentially described as a device that interferes with the mobile phone network, preventing communication between the phone and its nearby mobile phone signal tower/base station. Once the phone enters its interference range, the phone blocking device will interfere with its signal by emitting higher and stronger frequencies, causing the phone to enter a “blind spot”. Due to the complete disappearance of mobile phone signals, users will be unable to answer or make calls.

When we talk about mobile phones, we also refer to the new generation of smartphones that are already equipped with 3G and 4G LTE/5G technology. People may use them for VoIP calls through WhatsApp, Viber, Messenger, and more.

Now that we understand what mobile phone blockers are, we need to understand why they are essential. Why do I need a phone blocker? Commuters on trains and buses have become increasingly impolite and rude. They believe that they can act as they please without having to bear the consequences. Okay, use a gsm jammer to shut them up. They will lose their way and look around, trying to find out why their phones do not have a signal bar. Perhaps this is the price they pay to speak loudly on the bus and annoy other early morning commuters.

In summary, this is the basic purpose of the mobile signal blocker we sell, which must be implemented in places of worship for religious gatherings, such as mosques, churches, synagogues, temples, etc. Theaters, restaurants, workplaces, and most importantly classrooms. It goes without saying that every teenager now has the latest smartphones, which can disrupt classes and disturb other students, let alone cheat in exams.

In addition, governments around the world are currently considering the idea of installing such devices in prisons and other sensitive government areas.

Please always remember to use interfering devices with caution. Although being forced to listen to strangers chattering on the phone while on the bus may be annoying, a little consideration can still be very helpful. Explanation of interference range and output power: First of all, let’s say that the stronger the mobile phone signal in a place, the smaller the working range of the interference device. Therefore, it is recommended to check the reception of the phone in the area where the jammer needs to cause interference beforehand. This will determine the output power of the jammer you need.

The basic thing you need to understand about frequency interceptors is that they do not magically work according to the specifications mentioned, and will create a “dead zone” around them wherever you place them. They don’t work this way.

The three main factors that determine successful installation are output power, antenna type, and cooling system.

Although the mobile signal in a certain location is strong, all three factors can have a significant impact on its interference range, overall performance, and durability. For example, the performance of a signal interceptor with a total power of 8W is not as good as that of a device with a total output power of 15W. Directional antennas provide a wider interference radius because they concentrate all output power in one direction, while omnidirectional antennas provide a 360 ° coverage range, resulting in a narrower range. Although each meter is important, the impact is not significant. In addition, advanced cooling fans can prevent the jammer from overheating, resulting in a longer performance and service life of the jammer gps.

In short, only after considering all the above factors can you choose the signal interceptor that best suits your needs. Always remember the following points: the higher the wattage, the wider the interference range.

By comparing these two devices side by side, M 27 and M25 are almost identical. From the installation bracket, CPU, wiring, and interference head, M-27 is no different from its brother. Blinder is ready to use out of the box, including all necessary wiring, external speakers, CPU, and two GPS shielding heads.

Overall, the M27 is a high-quality and high-performance wifi blocker

M27 is suitable for small vehicles with a smaller appearance. M47 is used to cover weak points of small vehicles or protect large trucks or SUVs.

Installation is almost effortless. By becoming slightly familiar with automotive electronic devices, amateur installers can easily connect the device. All you need is a power supply and a ground wire. It is easy to wire the signal jammers head through a firewall through telephone type connectors, which are small enough to pass through the smallest hole. Then the rest is to install the GPS interceptor head. This is where it’s a bit difficult.

The installation brackets are independent of each other, which means that each side of the jammer head is supported by separate brackets. For normal operation, the jammer head needs to be completely straight and level with the road surface. This means that in order to install the pan tilt correctly, you must find 2 independent and completely horizontal surfaces on the car. If installed on the top of the bumper, this may be easy, but most people do not want to clumsily place two large cell phone jammer heads at the front of the vehicle. It is difficult to complete the correct head installation on many vehicles, which is why most Lens hood users create their own mounting brackets.

Once the head is installed correctly, M27 has made significant improvements compared to the old version. With a more powerful head and fully upgradeable CPU, this new device is ready for all new laser Radar speed gun developed. In most cases, this device will interfere with the LiDAR all the way to the muzzle. However, Blinder did encounter some interference issues.

For certain guns, such as the Ultralyte LR-B, occasional malfunctions may occur. Independent testing has shown that vehicles equipped with two gps jammer heads at the front of the vehicle cannot cover high reflective areas such as headlights. This is a particularly undesirable situation, as police officers are often trained to aim their headlights when they are unable to produce instant and fast readings. To solve this problem, a headlight laser protective cover may be needed. Laser veil is a liquid coating applied to headlights. Applying this technology to the headlights will greatly help Blinder achieve better interference effects.

Another solution is Blinder M47. This is the M27 with two additional interference heads. If users encounter interference when using the M27, two additional heads are very suitable for achieving better results. Two additional jamming heads will enable the vehicle to be bulletproof against most laser Radar speed gun in almost all cases.
