The Importance of Corresponding Frequencies between Interference Modules and Antennas in Cell Phone Signal Jammers

Cell phone signal jammers are devices that are composed of various interference modules with different frequencies. These interference modules need to correspond to the frequencies of the antennas. This article aims to explain the significance of this one-to-one correspondence and the potential issues that may arise if it is not maintained.

Why Corresponding Frequencies?

The interference modules in cell phone signal jammers are divided based on the signal frequencies used by mobile phones, ranging from 800M to 6G. Typically, mainstream cell phone jammers are equipped with 10-12 interference modules. These modules are divided according to the output signal frequencies, and the antennas are also divided based on the signal frequencies.

Optimizing Interference Effectiveness:

The frequencies of the interference modules and antennas in cell phone signal jammers must correspond one-to-one to fully utilize the effectiveness of the interference modules. Only by using antennas that correspond to the output frequencies and power covered by the interference modules can these signals exert a greater interference effect.

Potential Issues:

If the frequencies between the interference modules and antennas do not correspond one-to-one, several problems may arise. Firstly, the interference modules may not effectively cover the desired output frequencies, resulting in reduced interference capabilities. This can lead to incomplete blocking of cell phone signals, allowing unwanted communication to persist. Additionally, mismatched frequencies can cause signal leakage, where certain frequencies are not adequately blocked, compromising the overall effectiveness of the cell phone signal jammer.


In conclusion, the correspondence between the frequencies of the interference modules and antennas in cell phone signal jammers is crucial for optimal performance. Maintaining this one-to-one correspondence ensures that the interference modules can effectively cover the desired output frequencies and power. Failure to do so may result in reduced interference capabilities and signal leakage. Therefore, it is essential to consider this factor when designing and using cell phone signal jammers to ensure their effectiveness in blocking unwanted communication.
