The 14-band portable handheld Signal Jammer is a professional-grade wireless signal blocking device designed for security applications. This compact unit features advanced frequency jamming technology to effectively disrupt all major communication bands within a 20-meter radius (at -75dBm signal strength, actual range may vary depending on environmental conditions).
This multi-frequency jammer simultaneously blocks: CDMA, GSM, DCS, PHS/PCS, 3G, 4G, 5G (optional), WiFi 2.4G/5.2G/5.8G, Bluetooth, GPS (L1-L5), LoJack, VHF, RC (315/433/868/915MHz), NB-IoT, LoRa, Sigfox, and Z-Wave signals. It effectively prevents calls, SMS, internet access, wireless data transmission, GPS tracking, remote control operations, and other wireless communications to ensure complete information security.
The device features a portable handheld design with a high-quality nylon arm bag for convenient carrying and operation. Its advanced cooling system ensures stable, reliable performance during extended use. Each frequency band can be independently controlled (ON/OFF) for targeted jamming operations.
Powered by a built-in 7.4V 12000mAh Li-ion battery, the jammer provides 2.5-3 hours of continuous operation on a full charge. It supports both AC (100-240V input) and DC (12V car cigarette lighter) charging options for flexible power supply solutions.
