UHF VHF Jammers

For amateur radio communication, the VHF and UHF frequency bands are the frequency bands that radio enthusiasts use more frequently and conveniently. Whether it is at home, in the car, or in travel or work, there are U/V frequency band devices. accompany. So what is the U/V segment?

The VHF frequency band ranges from 30 to 300MHz, and the radio wave wavelength is 10 to 1m, so the VHF band is called the Microwave band; the UHF band range is 300 to 3000MHz, and the radio wavelength is 1m to 1dm, so the UHF band is called the Microwave Band. wave band.

How do different types of signal jammers work differently?

Different types of signal jammers work differently depending on their design and purpose. Here are some common types and how they work:

Noise Jammers:

How it works: They interfere with the signals in the target frequency band by emitting random electromagnetic noise. The noise signal covers the original signal, making it impossible for the receiving device to decode valid data.

Interference Jammers:

How it works: They are specially designed to interfere with signals in a specific frequency band, such as Wi-Fi, Bluetooth, or mobile phone signals. They reduce or eliminate the effectiveness of the target signal by emitting strong signals or interference signals of specific frequencies.

Directional Jammers:

How it works: They use directional antennas to concentrate energy in a specific direction to enhance the interference effect. This type of jammer can accurately target a certain signal source and is suitable for specific scenarios.

Omnidirectional Jammers:

How it works: Using omnidirectional antennas, it is able to evenly emit interference signals within a 360-degree range, suitable for applications that need to cover a wide area.

Frequency Selective Jammers:

How it works: They are designed to interfere with signals within a specific frequency range without affecting signals in other frequency bands. This type of jammer can be used to protect certain communications without interfering with others.

Dynamic Jammer:

Working Principle: It can automatically identify surrounding signals and adjust the interference frequency and intensity as needed. This can improve the interference efficiency while avoiding excessive interference.
