The handheld signal jammer is a high-tech product successfully developed by our factory using advanced domestic and foreign technologies in response to the continuous development of communication standards and based on the actual situation of domestic and foreign wireless communications. It can effectively shield (CDMA/GSM/DCS/2G/ 3G/4G/5G/WIFI) and other wireless signals, without any negative impact or interference on the communication and transmission of other electronic devices around you. This machine can effectively block the above wireless signals within a radius of 1-20 meters (depending on the strength of the on-site signal).

1. All are composed of the latest patch components and integrated circuits, easy to install and use, and have stable performance

2. The surface adopts the most advanced secondary oxidation treatment in the world and is made of aluminum shell with good heat dissipation.

3. The effective shielding distance radius is 1-20 meters. The interference radius still depends on the signal strength of the specific area.

4. Each frequency band can be controlled individually.

5. There is an obvious power indicator light on the visible part of the body.

6. Cooling fan, can be used directly in cars, car chargers and AC chargers

7. Easy to carry and concealed, low power consumption, no harm to human body and environmentally friendly
