(The signal frequency band of the jammer is customized according to the customer's location, and the power plug is also suitable for the customer's location, including European countries such as Germany and France, and various countries such as the United States, Canada, etc., the United Kingdom and Australia).
(Handy portable models of the jammer are supplied with a car charger)
130W output power
In terms of power, this signal jammer performs well with a maximum output power of 100-130 W and an output power of 10-30 W per frequency band. This jammer can achieve effective signal jamming in a range of 20 to 120 meters, and the range of GPS signal jamming can even reach 300 meters.
This powerful coverage makes it suitable for venues of any size, whether it's a small conference room or a large outdoor area, and ensures stable and efficient signal interference effects.
The interference range of the device is not only capable of covering regular communication signals, but also certain high or low frequency signals such as UHF and VHF, which makes it applicable in special scenarios. In environments where, for example, signals from remote devices need to be controlled, it can become an indispensable device that ensures that communication within the target area is fully controlled.
Modular design and safety protection, simple operation
The device has a modular design and each device can interfere with up to 6 frequency bands simultaneously. Users can flexibly choose the combination of interference frequency bands according to actual requirements. At the same time, it supports individual frequency band control, allowing users to accurately adjust the power of each frequency band and freely adjust from 0 to the maximum output power to match the signal strength of different environments. This not only improves the application flexibility of the device, but also prevents excessive signal interference from affecting the normal operation of peripheral devices.
In addition, this device is equipped with VSWR overprotection technology (isolator). When an abnormality occurs inside the device, this technology can effectively protect the module, avoid safety problems caused by overload or overheating, and ensure the long-term operation of the device. Whether in high-use environments or long-term unattended scenarios, you can use it with confidence.
Efficient cooling system to ensure stable and continuous operation
To support long-term stable operation of the device, this signal jammer is equipped with an efficient cooling system. The system consists of a radiator, three large top fans and four small internal fans that can quickly dissipate the heat generated during operation of the device, ensuring that the internal temperature is always within a safe range. This design not only extends the service life of the devices, but also enables efficient performance to be maintained in continuous operation.
In addition, the fan of the device has been optimized and the noise is reduced to a low level. Even when used in a quiet environment, it does not cause any obvious interference. This device is ideal for locations with long-term operation and high ambient noise requirements, such as conference rooms, concert halls or theaters.
Widely applicable to a variety of scenarios to meet specific requirements
Thanks to its powerful performance and flexible frequency band selection, this signal jammer is suitable for a variety of places where silence, confidentiality or information security is required. For example, it can effectively jam signals in conference rooms, classrooms, museums, theaters, factories and other places, creating a quiet environment while preventing information leaks.
It is also suitable for use in trains, buses and other means of transportation to prevent interference from passengers misusing communication devices.
In special environments such as hospitals or petrol stations, the device supports on-site testing to ensure that the normal operation of important instruments or equipment is not affected.
The device is extremely portable, measures 550 x 238 x 60 mm and weighs around 10 kg. It is equipped with 8 high-performance antennas and adapters, allowing users to deploy it quickly and use it flexibly. Whether it is for daily use or special scene requirements, this device can provide professional and reliable signal interference services.
Things to consider:
1. our jammers are tailored to specific frequency bands that are used in different countries.
2. follow the standard operating procedures (always connect the antenna before using the jammer).
