Multiband signal interference, wide interference, high applicability
This 8-antenna portable signal jammer has powerful multi-band signal jamming capabilities, handling interference with 2G, 3G, 4G mobile communication signals, as well as common frequency bands such as GPS (L1/L2+L5), WiFi 2.4G, Bluetooth and LoJack.
By interfering with several frequency ranges, it can effectively block different types of wireless communication devices, such as cell phones, GPS positioning devices, wireless cameras, etc., to prevent privacy leaks or interference with the calm atmosphere of important occasions. Whether in conference rooms, cinemas, classrooms or other places where signal interference is required (such as churches, funerals, etc.), this device can meet the need.
It provides users with an effective signal jammer solution suitable for a variety of application scenarios, particularly environments requiring privacy or security protection.
Portable design and multiple feeding methods for flexible use
This jammer is designed to be lightweight, with the unit measuring just 132 mm × 80 mm × 41 mm and weighing 800 grams, making it easy to carry or use quickly. This device features an integrated 4700 mAh battery that supports 1.5 hours of continuous use, allowing users to continue using it in mobile scenarios. At the same time, it is also equipped with a variety of power options, supporting power via a power outlet or car charger to meet the user's usage needs in different environments.
It's worth mentioning that this device supports use while charging, and can continue to operate normally even when the battery is low. Whether used indoors for fixed purposes or outdoors for temporary use, this scrambler can offer a high degree of flexibility and greatly enhance user convenience.
Efficient heat dissipation ensures stable long-term operation
To meet long-term operating requirements, this jammer is specially designed with an efficient heat dissipation system. The device is equipped with a cooling fan and a large radiator inside, which can rapidly reduce the heat generated by the device when in operation, ensuring that the jammer can operate stably under high-frequency, high-load conditions. Even in hot environments or when using the device for extended periods, performance will not be affected by excessive temperatures. This advanced heat dissipation design not only extends the life of the device, but also improves its reliability, enabling users to use it with greater confidence in complex scenarios.
Easy to use and adaptable to different environmental conditions
Operation of the device is designed to be simple and intuitive, making it easy to use even for inexperienced users. Each signal frequency band is equipped with an independent DIP switch, and users can freely choose to activate or deactivate a specific interference frequency band. At the same time, the LED indicator can display the device status in real time, making it convenient for monitoring and adjustment.
What's more, this highly adaptable device can operate normally in a temperature range of -10°C to +50°C and a humidity adaptability range of 5% to 80%. Whether it's a cold outdoor scene or a relatively humid or hot environment, it can maintain stable performance. This high environmental adaptability makes it suitable for use in a variety of complex conditions.
Wide-range signal interference, high output power
The jammer's interference radius is up to 40 meters (actual interference distance is affected by environmental signal strength) and output power is 4 W, which can meet most signal interference needs. Whether in a meeting room, event venue or private space where privacy is required, the device can provide a powerful signal interference effect.
Compared with ordinary jammers, its stable jamming capability makes it an ideal choice for protecting privacy and maintaining a quiet environment. By blocking unwanted signal interference, the device can help users concentrate more effectively and avoid external distractions. It is particularly suitable for use in situations where a quiet environment is required.
Please note the following considerations:
1. The interference frequency band of the jammer is customized to the customer's region.
2. Low-power jammers (such as portable models) may have difficulty interfering with high-power signal devices (such as high-power WIFI routers). To interfere with high-power equipment, you need to buy a high-power jammer.
3. Make sure you connect the antenna before using the jammer.
