Whether in a private place, company, school or movie theater... This high-performance mobile phone jamming device can give you the best signal shielding protection, allowing you to avoid privacy leakage.

This professional desktop high-power jammer is equipped with 4 external omnidirectional antennas, which can interfere with mobile phones/Wi-Fi/GPS within a radius of 50-150m individually/simultaneously. In addition, there are other tuning options or tunings depending on the interference band you need. A well-configured cooling system allows you to use it continuously for a long time, 24/7 for the best protection for your privacy or security.

In addition, its operation and use are also very simple. After receiving it, install the antenna, turn on the power supply, and wait for a while, and you will find that the frequency you need to shield has disappeared...
