The U-J300JW is a high-power 600W outdoor mobile network blocker featuring a software platform and cooling system. This advanced signal jammer contains six band jamming signal generators that transmit highly effective jamming signals targeting all cell phone and Wi-Fi devices within the blocking range.
When activated, the jammer utilizes high-gain directional panel antennas to create a continuous jamming radius of up to 600 meters, simultaneously disrupting RF communication frequencies from 700MHz to 2700MHz commonly used by cellular and Wi-Fi devices. The system employs the latest jamming technologies with ultra-high RF transmission power, ensuring stable signal shielding performance.
Once operational, the device transmits unique noise signals that create a "firewall" between transmitters and receivers (cell phones and Wi-Fi devices), effectively blocking communication.
