Texin BG-NZ50W Built-In Antenna Signal Jammer Detector 2G 3G 4G 5G 870MHZ to 5850MHZ Mobile Phone Signal WIFI Signal Shi

Product Introduction This machine is a new type signal jammer The high efficiency shielding only shields the effective signal reception and has no effect on the surrounding operator base stations This machine is designed to be covered by a built in high gain antenna and can be shielded from the operator s dual mode 2G 3G 4G 5G GPS WIFI and other signals in a shielding range of 5 10 meters depending on the strength of the base station signals Shielding so that all communications within the shielding range are completely interrupted from the outside world Due to the continuous enhancement of the signal coverage the shielding effect of the shielding device is poor This machine has proved through many experiments that the shielding effect reaches the best distance we use imported chips to improve efficiency and high gain built in antennas to enhance the coverage power It can be used in meeting rooms classrooms prisons confidential areas etc Feature 1 Built in antenna no loading and unloading convenient and quick implementation of signal shield 2 Equipped with a precision voltage stabilizing circuit it can be used normally even when the voltage fluctuates greatly 3 Original chips and circuit board ensure high efficiency stable performance and long life 4 Durable ABS shell waterproof wear resistant heat resistant 5 Convection ventilation holes and built in high efficiency heat sinks and fans to prevent local heat accumulation and efficient heat remo
