This compact wifi and cellular interference device features 12 antennas, designed to cover popular wireless signal frequencies, including 2G, 3G, 4G, 5G, WiFi, and GPS. It efficiently blocks these signals within a distance of 5-15 meters, safeguarding against data breaches and disruptions.
The body of the P-US-12 is constructed from black anodized aluminum alloy, ensuring it is both durable and resistant to oxidation and corrosion.
For the connection between its detachable antenna and the unit, a brass connector is utilized, offering excellent conductivity and long-lasting performance, which minimizes loss and maximizes efficiency during signal transmission.
This device includes a silent, efficient cooling fan and a vertically aligned heat sink, ensuring stable operation even during extended use.
The fan blades are meticulously aerodynamically shaped, allowing for rapid heat dissipation generated during operation while maintaining a low noise level, ensuring user comfort.
The built-in red indicator light located beneath the fan provides a clear visual cue of the device – operational status.

Usage Instructions
1. Position the P-US-12 in the desired area where signal blockage is needed, selecting an appropriate location tailored to the environment for optimum jamming effectiveness.
2. Sequentially attach the 12 antennas based on the antenna coding before operation initiation.
3. Activate the power switch, at which point the device’s indicator light will illuminate, signaling that it has commenced operation.
Frequently Asked Questions
How can I stabilize the device’s interference range?
Inspect the surroundings for large metallic objects or potential interference sources, and reposition the device to a more open space.
Ensure the antenna is correctly installed, modifying its angle if necessary to enhance interference performance.
What steps should I take if the device overheats?
Verify that the cooling fan is functioning correctly and remove any accumulated dust from the fan and heat sink.
Avoid prolonged use in high-temperature conditions, and consider using an external cooling solution if needed.
What actions are advisable if the jamming effectiveness is inadequate?
Confirm that the jamming feature is activated for all targeted frequency bands.
Adjust the interference strength to guarantee effective blocking even in high-signal environments.
