The prison signal jammer is designed specifically for high-security environments such as correctional facilities, military compounds, and government installations. This advanced jamming system provides comprehensive signal blocking capabilities across multiple frequency bands to ensure complete communication control.

With a powerful 300W total output, this system can effectively block signals within a 50-150 meter radius depending on environmental conditions and signal density. The jammer utilizes sweep jamming technology and can be equipped with either directional or omnidirectional antennas (12-15dBi gain) for optimal coverage.

Key features include PLL synthesized signal source for stable performance, screw controls for precise power adjustment, and slow start-up circuitry for enhanced reliability. The system includes over-temperature and VSWR protection, status/alarm LEDs, and comes in a fan-cooled rack enclosure with casters for mobility.
The jammer supports multiple frequency configurations including GSM (850-894MHz, 925-960MHz), DCS (1805-1880MHz), 3G (2110-2170MHz), 4G LTE (790-826MHz), WiMAX (2620-2690MHz), WiFi (2400-2485MHz, 5725-5850MHz), GPS (1570-1610MHz, 1200-1300MHz), VHF (135-174MHz), and UHF (400-470MHz).

Operating temperature ranges from -20°C to +50°C with storage capability from -40°C to +60°C. The system meets ICNIRP standards for human safety and includes a wireless remote control for convenient operation.
This professional jamming solution is ideal for prisons, military bases, government facilities, petrochemical plants, sports venues, theaters, VIP protection details, bomb disposal units, and other high-security applications requiring complete signal control.
