Full-band N-14-120W 5G Cell Phone Signal Blocker2.4-5.8Ghz Wifi Jammer up to 100M
The DXK N-14-120W is a full-band, directional power-adjustable 5G mobile signal blocker designed to block mobile phones, WiFi, Bluetooth, electronic watches, and other wireless devices often used for unauthorized communication or cheating. It plays a vital role in maintaining security and integrity during confidential meetings and standardized examinations.

This seventh-generation signal blocker utilizes cutting-edge technology to shield on-site devices from receiving mobile signals without affecting nearby base stations.. It adopts an aluminum alloy casing and has fast heat dissipation. Engineered with military-grade anti-drop and anti-collision design for superior performance.
And it combines the advantages of portable and desktop blockers, and has the characteristics of easy portability and high-power interference. The total power of 120W(each channel 5-10W) can quickly and effectively eliminate signal threats within the interference range. The built-in directional antenna array significantly enhances the effective shielding distance, which can range from 8 to 100 meters, depending on the strength of the surrounding base station signal.
