Effectively making subsections. Just interfering downlink and no interception on the base station.
. Extreme portability. The weight for machine itself and antenna is just 1.5KG
. Taking use of super-high frequency and mini-power interference technology. High efficiency.
. Slow start up design of circuit. These elements can maintain the stable operation condition with high integration.
. The jammer has 4 antennas, each output **3 watts ( output is adjustable )
. Adopt aluminium alloy materials and obtain high efficiency in heating and shielding
. With remte controller, adjustable outpower

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.

Notice
1. Be sure to connect all the antenna first before the power supply is switch on. Please do not take off antenna when the machine is working.
2. Antenna shall be used vertical to the ground. Working more efficiently.
3. Please dont put the jammer in the bad Condition of over-wet. Over-hot, high voltage and high magnetism.
4. The jammer shall be installed in the position with good ventilation, and large-scale things shall be avoided to ensure the shielding effect.
