Army VHF UHF Mobile Network Blocker Device Cell Phone Interrupter Aluminum
Mobile Network Blocker Description:
GW-J300JW High Power 600W Outdoor jammer With Software Platform and Cooling Fan,6 band jamming signal generators inside, which can transmit highly effective jamming signals targeting all cell phone and Wi-Fi devices within the blocking range. Once you turn the jammer on, with the help of its high-gain directional panel antennas, can jam up to 600m continuously and simultaneously, all the RF communication Frequencies 700MHz~2700MHz which are most commonly used by cell phones and Wi-Fi devices. Adopting the latest jamming technologies, jammer features ultra-high RF transmission power, making a stable shielding range around.
Once the system is activated, it transmits unique noise signal which creates "Firewall" between the transmitter and its receiver (cell phone and Wi-Fi device).
Mobile Network Blocker Features:
1. Ouput power 600W, Jamming up to SIX different jamming modules.
2. Can customize these frequencies AM, FM Radio, LoJack 173MHz, VHF, UHF, Walkie-talkie, interphone, Wireless Toys , FM Radio, Remote Control, 27MHz, 49MHz, 433MHz,315MHz, 868MHz, 450MHz, iDEN, CDMA, GSM, GPRS, DCS, PCS, AWS, WCDMA,UMTS,3G,4G,LTE 700, LTE 800, LTE 2300, LTE 2600, GPS L1,GPSL2, Galileo, Compass, Glonass, WIFI, Bluetooth, Spy camera, WIMAX, UAV, Drone, etc.
Mobile Network Blocker Advantages:
1. VSWR protection,
When there be antenna disconnect, full system will not burn out.
2. Waterproof Level: IP65
Good cooling system, Continuous operation, even in hot climates.
3. Each band have independent power supply.
4. Each channel can be controlled separately and simultaneously.
Manual adjustable output power with each channel.
5. Remote Monitoring(Optional)
Remote Monitoring available by IP Network
Remote Control Interface: RJ45
Mobile Network Blocker Application:
Prisons, military, government, Oil and Gas Storage Facilities and fields, Churches, Theatres, Libraries, Museums, Courts, Border Patrol and Drug Enforcement, Customs, mosques, etc.
