This portable wifi and cellular jammer is equipped with 12 antennas, mainly covering common wireless signal bands such as 2G, 3G, 4G, 5G, WiFi, GPS, etc. It can quickly and effectively shield these signals within a range of 5-15 meters to prevent information leakage or interference.
The P-US-12 shell is made of black aluminum alloy material, and the surface is anodized, which has durability, anti-oxidation and corrosion resistance.
The connection part between the detachable antenna and the device uses a brass connector, which has excellent conductivity and durability, ensuring low loss and high efficiency during signal transmission.
The Cellular signal jammer is equipped with an efficient silent fan and a vertically arranged heat sink to ensure that the device remains stable during long-term operation.
The fan blades are precisely aerodynamically designed, which can quickly discharge the internal heat generated during efficient operation and maintain low noise operation, ensuring that users are not bothered by noise during use.
The red indicator light embedded under the fan can intuitively understand the operating status of the product.

How to use
1. Place P-US-12 in the area where the signal needs to be shielded, and choose a suitable location according to the environment to ensure the best interference effect.
2. Install the 12 antennas one by one according to the antenna code before starting to use.
3. Turn on the power switch of the device, and the indicator light of the device will light up, indicating that it has started working.
FAQ
What should I do if the interference range of the device is unstable?
Check whether there are large metal objects or other interference sources around, and try to place the device in an open area.
Make sure the antenna is installed correctly, and adjust the antenna angle if necessary to optimize the interference effect.
What should I do if the device is overheating?
Make sure the cooling fan is working properly and clean the dust on the fan and heat sink.
Avoid using the device for a long time in a high temperature environment, and add an external heat dissipation device if necessary.
What should I do if the interference effect is not ideal?
Confirm that the interference function is turned on for all frequency bands that need to be shielded.
Adjust the interference intensity to ensure effective shielding even in an environment with strong signals.
