Detailed Product Description Product Name: Portable GSM Jammer Application: Small Handheld Portable Jamming Purpose Net Weight: 0.8kg Antenna Quantity: 8 Antennas Gross Weight: 1.5kg Working Time: 2 Hours Operating Temp: -10 To 50℃ Dimension: 125*75*35mm Storage Temp: -40 To +60ºC Color: Black Portable GSM Jammer Small Portable Lojack Jammer With 8 Antennas​   Updates   1． It can be used to jam GSM, 2G, 3G, 4G, WiFi, GPS, LTE, DCS, Lojack, Wimax and any other customized signals. 2． Both AC and DC power supply, car adapter for anti-tracking. 3． Each band can be turn on and off independently. 4． Updated for times with higher power for longer jamming range and better cooling system, heat sink to make the jammer be cool while working.   Description 1. TSL-N8 is a portable GSM jammer, implementing the most effective and reliable RF jamming technology to prevent the leak of confidential information or unwanted usage of cell phones, Wi-Fi devices and GPS devices.   2. TSL-N8 has 8 sets of 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 omni-directional antennas, TSL-N8 can jam continuously and simultaneously, all the RF communication Frequencies 850MHz~2660MHz which are most commonly used by cell phones and Wi-Fi devices. Adopting the latest jamming technologies, TSL-N8 portable gsm jammer features ultra-high RF transmission power, making a stable shielding range around. 3. 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).   4. Besides, TSL-N8 can prevent the leak of confidential information leak via cell phones or unwanted GPS location leak.   Specifications   Output port Frequency Output power Jamming range 4G LTE800 780-894MHz 2 Watts 5-20 meters CDMA800 869-894MHz 2 Watts 5-20 meters GSM900 925-960MHz 2 Watts 5-20 meters GSM1800 1805-1880MHz 2 Watts 5-20 meters WCDMA 2110-2170MHz 2 Watts 5-20 meters WiFi 2.4G 2400-2485MHz 2 Watts 5-20 meters 4G LTE 2600 2620-2690MHz 2 Watts 5-20 meters GPS L1 1975MHz 1 Watts 5-20 meters Optional 1.

First, please attach the antennas to the body. Then use the charger to charge the jammer before you use it for the 1st time. Please make sure that the jammer is charged for 4 to 5 hours. 2. Once you turn the switch on, devices like cellphones (2G ~ 4G LTE) and WiFi & Bluetooth devices will not be able to transfer any data or make calls within the blocking range.The metal case of TSL-N8 provides a very firm frame and the fans inside makes it possible for long term operation without overheat. Each antennas has its very own switch so you can turn them off separately according to your needs (like when you only want to block GSM phones and let CDMA phones work just fine). 3. Rechargeable battery inside could provide a working time over 1.5 hours continuously. You could charge the jammer via the lighter in your car or use AC/DC in your home.This tiny device could help those who want to control or block phone use (voice call and internet use) around with very easy steps. All you need to do is just to turn the jammer on and it will automatically start to send out jamming signals. Within the functional range, all wireless device, including cellphone, mobile phone, GPS, WiFi device, will not be able to use as long as the jammer is on.   Features l  8 High Power jamming signal generators inside. l  Omni-directional Antennas. l  Light weight design, easy to carry. l  Can block 8 frequency bands continuously and simultaneously. l  The frequencies can be cotomized for different requirements. l  Total output power up to 20 watts. l  With internal battery, recharged by DC charger or car charger. l  Can work while charging. l  Separate switch for each band with LED Light. l  Inside cooling fans.   Application l  To prevent unwanted usage of cell phone l  To prevent the leak of confidential information l  To prevent the leak of GPS location l  To prevent the remote-control cell phone bomb l  For School; For Exam; For Church; For Hospital...   Customized Isolating Signal Bandwidth   CDMA 851-894MHz GSM 925-960MHz DCS 1805-1880MHz PCS 1930-1990MHz 3G 2110-2185MHz 4G (LTE) 725-785MHZ 4G (Wimax) 2300-2410MHZ Lojack 167-175MHZ RF Radio 315MHz RF Radio 433MHz GPSL1/Glonass 1575.42MHz VHF 135-175MHz UHF 435-475MHz GPSL2/Glonass 1227.42MHz Wireless Camera 1.2G 1100-1200MHz Wireless Camera 2.4G 2400-2483MHz Wi-Fi/Bluetooth 2.4G WI-FI, 5G 5500-5900MHz   Wecome to do OEM/ODM, we can do customized frequency based above frequencies.   Whip antenna specification   Electrical Specifications Frequency Range The same as the jammer channel Impedance 50 Ohm VSWR Gain 2dBi Polarization Vertical Radiation Direction Omni Max.
