Product Description

240W Rackmount High Power Cell Phone Signal Jammer 3G Signal Scrambler



Product Description


A big merit of this rockmount high power cell phone signal jammer is that each band can adjust RF power output level or turn off without influencing the other bands' operation. The original antenna is external double channel directional panel antennas and you can select antennas to provide more flexibility regarding jamming coverage. The jamming coverage of this jammer is so strong that the jamming range could reach 500m, but the jamming range is also determined by the strength of signal in given area.


This device can affect five different frequency ranges at the same time, they are CDMA 800(850 to 894MHz), GSM 900(925 to 960MHz), GSM 1800(1805 to 1880MHz), GSM 1900(1920 to 1990MHz) and 3G(2110 to 2170MHz). However if your do not want to shield all the bands, you can choose which band to use according to your requirements and necessary. The total output power of this device is 240V, and power supply is 50 to 60Hz, 100 to 240V AC. There would be AC adapter (AC100-240V-DC27V) to match this 70kg weight jamming device.


Advantages and Features

  • • Aluminum-alloy casing with high protection has high resistance to dust, water and corroding.
  • • Heat sink designing combing with the fans to make system in a cooling status.
  • • Special technology to prevent interference between each frequency band.
  • • Only interfere downlink frequency of mobile system, without disturb normally working of Base Stations.
  • • Frequency bands and output power selectable.
  • • Each frequency band controlled by independent RF ON/OFF switches.
  • • Power of each frequency band can be adjustable independently.
  • • Circuit protection to ensure system will not burn out in case of antenna short circuiting or disconnection.
  • • Antenna type options, directional or Omni-directional antennas option.
  • • Easy operation and installation.
  • • Keep for upgrade module installation.
  • • Working 24 hours/365days continuously
