Product Description
Cell Phone Signal Jammer 16000mAH GPS Lojack WiFi 21 Antennas
This advanced 21-antenna cell phone signal jammer effectively blocks GPS, Lojack, WiFi, and cellular communications. By transmitting signals on the same radio frequencies as mobile devices, it disrupts communication between phones and base stations, preventing signal transmission and reception within its operational range.
Applications
Ideal for locations where silence is expected and phone calls would be disruptive, such as entertainment venues, theaters, conference rooms, and secure facilities.
