900W Cell Phoner Signal Jammer Each Band Can Work Independently for Prison

This 9 Bands Waterproof Adjustable High Power Phone Jammer with upgrade function for Prison is specially customized to accommodate a fully integrated broad band jamming system which provides the ultimate solution for Prison, Military, and Police convoys or VIP protection.

The 9 modules are controlled separately and they can also work simultaneously. The jamming frequency can be upgraded to more than 16 Bands. Each module with antenna can be used as a single jammer.

The prison jammer is waterproof and portable. The jammer case is our patent design, allowing installation in deserts and other regions with heavy rainfall or bad weather conditions. The Frequency band is optional. Furthermore, the high power jammer comes with excellent heat dispersion capabilities.

• Heat sink design combined with fans maintains the system in a cooling state.
• Special technology is implemented to prevent interference between each frequency band.
• The device only interferes with the downlink frequency of the mobile system, without disturbing the normal operation of Base Stations.
• Frequency bands and output power are selectable.
• Each frequency band is controlled by independent RF ON/OFF switches.
• The power of each frequency band can be adjusted independently.
