J250CW High-Power 700W Prison Jammer System - Digital Synthetic Multi-Band Shield

The J250CW is a state-of-the-art, high-intensity RF interference system designed for permanent installation in high-security environments such as prisons, military compounds, and sensitive governmental facilities. Utilizing advanced digital synthesis technology, this 700W powerhouse creates a definitive "no-communication" zone, effectively cutting off transmission power across all major cellular, data, and radio bands from 20MHz to 6000MHz.

Massive 7-Channel Power Shield

The system is architected with seven independent high-power modules, each delivering a consistent 100W (50dBm) of output power. This high-density energy distribution ensures that signals from CDMA, GSM, DCS, LTE (4G/5G), and high-speed WIFI are completely neutralized. The use of digital synthetic signal sources provides a more effective and stable interference performance compared to traditional analog VCO systems.

Strategic Sectoral Coverage

Equipped with a set of 7 high-gain antennas (13-15dBi gain), the J250CW is optimized for precision sectoral jamming. With a 90-degree working angle, security integrators can strategically position multiple units to build a perfect 360-degree perimeter shield without "bleeding" signal into unauthorized neighboring civilian areas. The blocking radius extends from 50 to 600 meters, depending on the local signal environment.

Industrial Design & Centralized Control

• All-Weather Reliability: Engineered for continuous 24/7/365 operation in any climate, the unit features a ruggedized chassis with a systematic smart cooling system (integrated heat sinks and high-performance fans).
• Centralized Management: Multiple J250CW units can be deployed across a large facility and centrally controlled via a management hub, allowing for real-time monitoring and tactical adjustments of individual frequency channels.
• Advanced Safety Standards: The emitted signal intensity complies with national standards for environmental electromagnetic wave health. The device is designed to disrupt the link between mobile devices and base stations without causing harm to human health or damaging the cellular devices themselves.
• Versatile Interference Range: Coverage includes 450MHz, 800MHz, 900MHz, 1.8G, 2.1G, 2.4G (WiFi), and the 3.6G bands, with customization available for the 20MHz-8000MHz spectrum.

Detailed Technical Specifications

The J250CW is the definitive solution for large-scale institutional RF control, providing a reliable, high-power barrier against unauthorized communications in the most sensitive operational environments.
