Directional Antenna High Power Mobile Phone Jammer 4 Channels 200 W
Mobile Phone Jammer Description:
Built-in Directional Antenna Prison Cell Phone Jammer GW-J255CAW have super design, user no need to install antenna again, High power 200W with High gain Built-in Directional Antenna will jam long range. 4 band waterproof jammer just use one antenna, The Jamming Radius depends on the strength signal in given area. All Cell Phones in vicinity of GW-J255CAW will be totally BLOCKED and will not be able to receive or dial outgoing calls. When this one effect the mobile the display will show "NO SERVICE".
designed for blocking GSM and 3G Cellular Networks and all kinds of Cellular standards in the world.
GW-J255CAW prison jammer will jam four frequencies: (optional)868MHz, iDEN, CDMA, GSM, GPRS, DCS, PCS, AWS,WCDMA,UMTS,3G, etc.
Mobile Phone Jammer Advantages:
Built-in Directional Panel Antenna, no need to install antenna again.
1. Good cooling system with cooling fan inside
2. Each bands can adjust RF output power or turn off without influencing the other bands operation
3. VSWR circuit protection to ensure system will not burn out should there be antenna short circuiting or disconnection
4. Work non-stopped
Cover interface standards:
1. CDMA 800: 850 to 894MHz
2. GSM 900: 925 to 960MHz
