An Introduction to Jammers

 

Interference causes disturbance in wireless communication. Jamming an antenna is all about interference with wireless communications. A jammer antenna is a kind of antenna used in creating interference with radio signals or noise. This interference is created to stop the battle of the antennas.

A military jammer antenna is used to radiate interference in the signals of the opponent’s radar. It also blocks the receiver’s signals with higher levels of energy signals. In this blog, we will discuss jammer, how it works, its benefits, and the special features of jammer antenna.

What is Jammer?

We discussed a few things in the above section related to jammers. Now, let us have a detailed study on the jammer. A jammer is a kind of device that helps to block signals from reaching someone. Jammers come in various types such as cell phone jammers, handheld jammers, or radar jammers.

This device is used in several electronics and communication devices. There are different kinds of jamming used for various purposes. From cell phones to GPS receivers, jammers are widely used in many devices.

Different kinds of jammers

Jammers come in different types. It is necessary to know the different kinds of jammers to know their functions and benefits. Read on to know the various kinds of jammers to understand their features:

1. GPS jammers

GPS jammer is a special kind of Jammer Antenna that helps to stop the transmission of location tracking service. It comes in different shapes and sizes. GPS jammer is a kind of standalone jammer that is very small. However, a GPS jammer can work only in a small area. It cannot be used for large vehicles.

2. Cellphone jammers

The next kind of jammer is a cellphone jammer. It can be used in blocking signals of every mobile phone. Cellphone jammers stop different frequency bands like CDMA, 3G, GSM, and 4G. Cellphone jammers come in small or large sizes. Short-range jammers are very small whereas larger jammers are very powerful and high-end models.

3. Internet jammers

Internet jammers can stop the transmission of devices with internet service. You can use an internet jammer in Wi-Fi routers and Bluetooth. It is one of the safest jammers to use in different internet-like devices to stop transmission. Moreover, these jammers protect your data from hackers and maintain its privacy as well.

Types of jamming techniques  

Jamming techniques are of 2 kinds namely noise techniques and repeater techniques. Some of the most popular types of noise techniques include sweep jamming, spot jamming, and barrage jamming. On the other hand, DRFM jamming is a type of repeater jamming. Let us have a look at the types of different jamming techniques in detail:

A. Noise Techniques

Under noise techniques, there are 3 kinds of jamming techniques such as:

·      Spot jamming

Spot jamming is a type of noise technique in which the jammer focuses all power on a single frequency blocking the signals of frequency-agile radar.

·      Barrage jamming

The next jamming technique in a high jammer antenna is barrage jamming. It is a technique of jamming many frequencies with one jammer. Barrage jamming is not as powerful as other kinds of jamming techniques.

·      Sweep techniques

Another type of noise technique in an anti-jammer antenna is the sweep technique. It is a process of shifting the power of jammers from one frequency to another. It can jam multiple frequencies speedily at different times.

B. Digital Frequency Radio memory or DFRM

This is a kind of repeater technique that alters and re-transmits received radar energy. It is used widely in different kinds of jamming antennas.

Benefits of using jammers

A jammer is a kind of device that blocks signals in the opponent’s signals. It comes in different shapes, sizes, and patterns. Some of the major benefits of military manpack jammer antenna are as under:

1. Protection from location tracking

One of the biggest problems at different places is location tracking. We cannot avoid the problem of location tracking quite often. GPS tracks your location every time. During these times, you can use a jammer and block signals. It can effectively stop GPS transmission and protect your data from hackers.

2. Good for banks and educational institutions

Today, a jammer is used in many educational and financial institutions. It can stop cheaters and hackers to hack your data. Jammers also jam signals and protect data.

3. Stop spying and bugging attempts

Another benefit of using a jammer in the Yagi antenna is that it stops spying and bugging attempts. You can stop someone from snooping by attaching a jammer in a UHF antenna. Jammers are simple to use for FTS antenna and different types of antennas. They are also cost-effective and help to block the bug’s receiver and prevent it from getting commands.

4. Reduce the use of cellphones

Jammers are widely used in prison to reduce the use of cell phones. They are attached to the Vhf antenna at many places. Cellphone jammers in High Gain ATC Antenna help to reduce unwanted mobile calls. They also reduce illegal activities by reducing cellphone calls.

Things to consider while buying a jammer

While purchasing a jammer for High Gain Helical Antenna, you must keep in mind certain things such as:

Ø Size

The first thing to look at while buying a jammer is the size. If you want a jammer for a small area, choose cellphone jammers. On the other hand, you must pick the desktop models if you want to jam the signals for a long time in a larger area.

Ø Cost of jammer

The next thing to look at while buying a jammer is the cost. Cheap jammers can block mobile phone signals. They work on batteries and cost between $30 and $60. Apart from that, the cheap jammers will also cover a small area.

If you want a high-quality jammer, choose pro models. These jammers cost around $500 and can block every type of signal such as Radio communication, Cellular, and so on.

Ø Installation

Some jammers come assembled while some jammers contain accessories to assemble. You can choose any jammer according to your need.
