Product Description Two-in-one and three-in-one jammer device can be gained with the highly developed technology now. But people can seldom see the five-in-one advanced jammers which can cut off the signals of the 3G mobile phones, GPS, WiFi, VHF, UHF at the meanwhile, not until this 12W Desktop 8 Antenna 3G Cellphone GPS Bluetooth VHF UHF Signal Jammer comes this goal has been achieved.First as 12W high output power has been applied on this 3G cellphone GPS Bluetooth VHF UHF jammer so the jamming effect is powerful – up to 25 meters based on the signal strength in the detailed place. Thus unlike many other desktop jammers at most have 6 antennas this is a desktop 8 antenna jammer, and because of this designed it can cut off the 9 frequency bands CDMA GSM DCS PCS 3G GPS WiFi VHF UHF without difficulty at the same time. So in this way people’s requirement such as obtain peaceful condition, get rid of the mobile phone and GPS signal tracking device, blocking signals of the walker-talkie and protecting their network can come true.Because of the good functions this 3G cellphone GPS Bluetooth VHF UHF jammer can be applied in places where need peaceful environment as the classroom, meeting room, church, library, and so on or the places where mobile phones  are prohibited as the prison and military.Manufacturer SpecificationsIsolating Signal Bandwidth:-CDMA(851MHz-894MHz)-GSM(925MHz-960MHz)-DCS(1805MHz-1880MHz)-PCS(1930MHz-1990MHz)-3G(2110MHz-2185MHz)-GPSL1(1500MHz-1600MHz)-WiFi 2.4G:(2400MHz-2500MHz)-VHF 135MHz-175MHz-UHF 400MHz-470MHzAvailable system:World wide cell phone networkPower supply:AC adapter (AC110-240V, DC9V)Operate time:24 hours continuousSemidiameter of interception:1-25 m(-75dBm)Antenna: 8 pcs ( Please fix the antenna follow the mark in the unit)  Power consume:12WWeight: 3.56 KGDimension: 240mm(L)×210mm(W)×51mm(H)Package Contents8 Antenna Powerful WiFi GPS VHF UHF 3G Mobile Phone JammerPower AdaptorAntenna*8 Important Notes for Jamming Distance: The jamming distances we mentioned on website are for customer's reference only.
