Rd explosion-proof cell phone jammers

Technology
1. Low power consumption. Can work 7-8 hours.
2. Effectively making subsections. Just interfering downlink and no interception on the base station.
3. Extreme portability. The weight for machine itself and antenna is just 12.6KG
4. Taking use of super-high frequency and mini-power interference technology. High efficiency.

5.Slow start up design of circuit. These elements can maintain the stable operation condition with high integration.

6. The jammer has 4 antennas, each output 2-3 watts ( output is adjustable )

7. Adopt aluminium alloy materials and obtain high efficiency in heating and shielding

8. With monitor on internet

Features

1. Show the working power on the shell with green lights

2. Mini size medium power cellphone jammer

3. Low weight and nice texture and color

4. To block wireless phone communication links within an effective area

5. No transmissions or receptions of cellphone call in coverage area

6. All specified frequency bands will be blocked simultaneously

7. No harm to human body

Theory gist of interception capacity

Maintain the wireless communication must have enough SNR, so that can ensure the effective receiving of signal and finish communication. Our jammer for mobile communication signal can destroy signal receiving condition for cell phone and cut off the connectioin between celll phone and base station by producing intercepting signal that can receive the same frequency with cell phone.

The power of jammer is limited in a certain range. The interception semidiameter of non hurdle space is decided by via attenuation and signal level of receiving base station. Covering semidiameter can be known by calculating out, outputting channel power, signal level of base station and gain of covering antenna.
