Best GPS jammers for 2020

In 2020, a person has at least one device that makes life easier. Technology does not stand still, but is developing at an incredible speed. Mobile phone, tablet, car alarm, smart home technology are not a luxury for a person, but affordable accessories. But there is a minus that not everyone knows about. These devices can be disabled in a few minutes with a special device that is cheap. If it falls into the wrong hands, it could be worth a good deal or reputation. Such a device can disable communication in the entire building or disable the alarm, hide the route of movement. So, what else a GPS signal jammer can do and what jammers are, we will tell below.

What is a RF jammer?

A radio frequency jammer is a specially designed device that helps protect your device from wiretapping. It protects all kinds of alarms, control panels and so on.

How did jammers appear?

King Abdullah II ibn Hussein of Jordan read a prayer in the temple, but he began to be annoyed by the calls of mobile devices, which were carried from different directions. People forgot to turn off the sound or just didn't want to do it. So in 2001, he decided to turn to engineers to create a small gadget that could jam the signal. The king wanted to read the prayer only in perfect silence.

Prior to this, the signal jammer was used only by the military against wiretapping.

Types of jammers

There are three types of jammers. Each of them is designed to fulfill its own task.

Stationary

If you want to use the jammer only in one place, then it is better to buy a stationary version. To use it, you need a network connection. Of the minuses - heavy weight, of the pluses - you can generate "white noise" from 10 radio frequencies, which improves the quality of work.

The main function of stationary silencers is to protect against wiretapping of telephones, video cameras and even microphones. Attackers can use valuable data for their own purposes. If this is a wife who is jealous of her husband, then this is not so scary, and if the situation concerns financial transactions, then it is better to reinsure yourself and provide a signal silencer.

Large companies can use this device to block incoming and outgoing calls and messages. This is done to ensure that employees are not distracted during working hours, and all their energy was directed to work. This is necessary for important negotiations or meetings. Such a device is already being used in big cities.

Another use case is cinemas, theaters, temples and mosques. Since the use of telephones in these places is not desirable, but not everyone agrees to abide by this rule.

It is also relevant for institutions of the Federal Penitentiary Service system, where prisoners cannot use telephones, but it is not always possible to control this. The small device solved the problem.

The radius of the muffler can vary significantly, but, on average, it is from 30 meters or more.It depends on the parameters of the device and the location of the nearest tower that transmits the signal.

Portable

The second type is portable. The main advantage of such a device is that you can take it with you if necessary. Weight - only 300 grams.

No one around you will notice that you have such a signal jammer. You can take it to a meeting or meeting, and if necessary, not noticeably turn it on. Battery life is on average 1 to 3 hours.

Locking covers

The special case has two compartments. One of them completely blocks all signals, and the second protects against harmful radiation.

Practical applications

Many people do not understand why a device such as a jammer is needed at all. That is why it is important to analyze the types and applications of such a device.

cellular

Jammers of this type are needed to protect against wiretapping. They also suppress the signal of all calls and messages. Thanks to this, perfect silence can be created. This way the indoor atmosphere will be conducive to any kind of activity - meditation, watching a movie or an important meeting.

Since in 2020 everyone uses one or more phones, this is relevant. Especially in schools when teaching or important exams. It is difficult for teenagers now not to use the phone and devote time only to study. If there are such jammers, then children will not be distracted by gadgets.

Wi-Fi / Bluetooth

The main task of such a device is to block the channel for transmitting video from a surveillance camera. Often used in banks, shops and offices. A small jammer helps keep sensitive data confidential.

Audio recording

In order for no one to be able to record conversations in the room, a noise generator is used. There are two types of recording prevention, acoustic cancellation and ultrasonic.

The first type creates interference from several voices, and the second, with the help of ultrasound, creates interference that is not perceived by a person's hearing, but blocks the recording from any device (phone, voice recorder).

Such a device takes up a lot of space, but looks like a regular speaker. Weight - from 2 kilograms or more. You can control it using the remote control.

Radio

Another option is Antishanson. With its help, you can turn off the radio in a taxi or other transport, where the music does not suit the passenger. It is rarely used.

GPS / Glonass

The GPS jammer blocks the reception of signals from satellites. This way, no one can get data about your location, speed and stops.

How it works? To determine the location of a person, it is necessary to receive a signal from three satellites. This jammer creates "white noise", which in turn creates interference. Thus, no signal is received.

The range of the suppressor depends on its power, favorable or unfavorable weather conditions and obstacles to signal receipt. When choosing, these parameters must be taken into account.

In order to understand how this works, you can recall the situation when a car drives into an underground tunnel. Since it does not catch a signal there, no data is received from the satellite.

Such an anti-tracker is a small device that must be installed in the car's cigarette lighter. Most often, this option is used by delivery couriers, so that the employer can not trace where the car is now. And also truckers who are carrying valuable cargo. Such an anti-tracker blocks the GPS and Glonass satellite signal. Some also have a GSM silencer.

Also, such a signal suppressor can be used by a person who does not want his wife or husband, mom or dad to know about his movements.

Where can I buy? There are several options for where to purchase this device - it can be an online or offline store. There is a large selection of devices on AliExpress, but before buying, you need to pay attention to the rating and reviews of the seller. You should buy only proven models, then the device will last a long time and will do its job efficiently.

How to make a GPS jammer yourself

In order to create this device on their own, a person must have initial skills in working with electronics. If they are not there, then it is better to purchase the device in the store. Its cost is quite budgetary.

This will require the following details:

• Generator;
• Jamming frequency setting circuit;
• Block;
• Antenna.

The most important detail is the generator. It must be tuned to the desired frequency - 1227 or 1575 MHz.

The suppression frequency setting circuit can be closed-loop or open-loop.

The block is needed to increase power and increase the range.

When choosing an antenna, it is necessary to be guided by the EHV coefficient. It can be up to three.

A power supply is required for operation. A lithium ion battery will do.

But if you do not correctly connect the necessary parts, then the device may not properly jam the signal or not work at all.

How to choose

Before buying such a device, you need to study the reviews, and pay attention to the main characteristics:

1. An important parameter is power. It must be indicated in the characteristics.
2. Signal hold. If the Chinese models can work intermittently, then the domestic ones are more durable and work better. The cost of the latter is higher, but it's worth it.
3. Housing. When choosing, you should pay attention to the material of the case and its assembly. Metal is not the best option. It is better to choose a model made of good plastic.
4. Battery. If you need to take the device with you, then you need to pay attention to the presence of a battery. Automobiles work from a cigarette lighter.
5. Number of frequencies.

Jammer disguise

Portable jammers do not take up much space and can easily be taken with you in your bag. But there are institutions and offices in which all personal belongings are checked. For such cases, devices were specially designed in the form of ordinary objects. It might be a standard pack of cigarettes that won't get attention or a briefcase.

Stationary mufflers can be made for any interior item.

Are jammers harmful to human health?

People who only want to use a signal suppressor are interested in the question of the harm of this device to the human body. More than one experiment was carried out that was able to prove that the jammer does not affect the human condition in any way.

How to find a jammer

This is a question that a person who has at least once faced the suppression of car alarms from the outside can ask himself. One of the best options is to buy a special device called a field indicator (bug detector). He guarantees the result.
