Are high-power handheld mobile phone signal jammers good? What to pay attention to when using
Small size: hand-held design, can be mastered with one hand, the size is equivalent to the common mobile phone or walkie-talkie;
Portable: It can be put into a pocket or a shoulder bag, and can be hung or worn on the arm and belt (for police);
High power: can effectively shield all common mobile phone signals within a radius of 5 to 15 meters;
Stability: Exquisite ventilation and heat dissipation design ensures that even if the host works for a long time, it will not affect the working stability due to poor heat dissipation;
Battery power supply: rechargeable battery power supply, can be used repeatedly, there are two ways of AC charging and vehicle charging;
Professionalism: It can selectively shield mobile phones of different standards;
Personalized customization: Customize different types of shielded signals for different countries, regions or different shielding requirements;
technical parameter
Shielding range: radius of 5 to 15 meters (-75dBm, in an indoor transparent environment, depending on the distance of surrounding base stations)
Transmitting power: whole machine ≥ 2W
Shielded signal types: GSM (Mobile/Unicom 2G), CDMA (Telecom), DCS (Mobile/Unicom 1800M), 3G (Mobile TD, Telecom CDMA2000, Unicom WCDMA)
Can add and change signal types: GPS, Wi-Fi, Bluetooth, etc.
Output channel: Four channel output, with frequency band switch, which can be selected and shielded for mobile phones of different standards
What should I pay attention to when using the shield?
All antennas must be screwed on before starting work;
When using the charger for the first time, the continuous charging time shall not be less than 12 hours;
Do not put the hand-held cell phone jammer into water or close to the fire source, and do not use the jammer in places with excessive humidity, overheating, high voltage or high radiation;
Under normal use, the antenna should be perpendicular to the ground to obtain the maximum shielding range.
