250 Watt High Power Cell Phone Jammer Large Range Cooling Fan For Prison
Cell Phone Jammer Introduction:
GW-J250CW prison Jammer is more effective than other Cellular Jammers, as the RF jamming is regulated with a directional jammer feature. This helps focus the jamming wave on desired areas only.
With superior design, the prison Jammer keeps jamming for all cellular phones standards.
Cell Phone Jammer Advantages:
1. Jammer Unit housing unit is waterproof and heat sink design.
2. Good cooling system with cooling fan inside
3. Each bands can adjust RF output power
4. Have switch to turn on or off each bands without influencing the other bands operation
5. VSWR circuit protection to ensure system will not burn out should there be antenna short circuiting or disconnection
6. Work non-stopped
Cover interface standards:
1. CDMA 800: 850 to 894MHz
2. GSM 900: 925 to 960MHz
3. GSM 1800: 1,805 to 1,880MHz
4. GSM 1900: 1,920 to 1,990MHz (PCS)
5. 3G: 2,110 to 2,170MHz
6. Wi-Fi: 2,400 to 2,500MHz
7. GPSL1:1570-1580MHz
8. 4GLTE: 700-800MHz
9. 4GWIMAX: 2620-2690 or 2345-2400MHz
10. CDMA450: 450-470MHz
11. You can select four or five of above frequency bands you need in a jammer
12. Total output power: 200-250W
13. Jamming range: up to300m, the jamming radius still depends on the strength signal in given area
14. External Omni-directional antennas or directional panel antennas ,all the TX frequency covered down link only
15. Power supply: 50 to 60Hz, 100 to 240V AC
16. With AC adapter (AC100-240V-DC27V),
17. Dimension:520(l) x 300(W) x 190mm(H)
18. Full set weight: about 30kg(Used of external Omni-directional antennas)
Cell Phone Jammer Application:
Prisons, military, government, mosques, etc.
