This powerful 8 antennas portable cell phone jammer uses a longer gain omnidirectional antenna that can interfere with a wider range of radii, up to 25m. It can interfere with devices that rely on the 2G 3g 4g wifi gps lojack signal band. The 8000 mA Ni-Mh and the built-in fan cooling system ensure that it can be used continuously for more than 2.5 hours.

Advantages:

- 8 Bands 5.6W with Ni-Mh battery 8000Mah, working 2.5 hours support use while battery charging.
- With longer 2.0dbi gain omni antennas, shielding radius (2-20) meters at -75dBm with high gain omni antennas.
- With DIP switch, separate switch for each band, accompanied with a working LED light.
- Could be used in car directly, with car charger and AC charger.
- Inside cooling fans and bigger heatsink design ensure the device to work continuously

Notice:

Do not power on if antennas are not connected one by one.
Do ensure the antennas are properly connected before usage, the functional coverage would be greatly affected if antennas are not installed correctly.
When power on, keep it away from computer, notebook PC, television, audio and AM/FM radio to prevent interferences.
The normal operational temperature is about 45-60° C. If the temperature is higher than the above, turn off the power immediately and contact local agent for help.
Placing the device on higher position for better coverage, recommend 2 meters high
