Effective signal jamming function
This portable signal jammer is known for its excellent performance and wide applicability. It is equipped with 8 frequency band antennas, which can easily interfere with mobile communication signals, including GSM, CDMA, DCS, 2G, 3G, 4G, 5G, etc., and can also effectively interfere with Wi-Fi 2.4G, GPS (L1 -L5) and LOJACK signal. (This is the default configuration, the frequency band of the jammer's jamming signal can be customized)
This multi-band jamming capability makes it a truly versatile jamming device, capable of blocking all types of mobile communications, wireless networks and GPS positioning signals. What's more, the device features an interference radius of up to 50 meters, which is wider than the range of most portable jammers on the market, offering users stronger signal interference capabilities.
This comprehensive and effective interference function is particularly suited to application scenarios requiring a high level of privacy protection or information security, such as confidential meetings, examination environments or sensitive locations, truly responding to diverse needs in different scenarios.
Powerful performance and portable design
As a high-performance signal jammer, the device has an astonishing 28 W output power, with 3 to 4 W in each frequency band, and is equipped with 8 high-gain omnidirectional antennas. This configuration ensures that the device can always interfere stably with a variety of signals in complex environments.
Whether it's high-intensity communication signals or GPS positioning signals that are difficult to interfere with, this device can handle them with ease.
At the same time, the design of this jammer pays great attention to portability.
