A self-developed wall mounted mobile phone WiFi signal blocker. It consists of antenna, RF amplifier unit, multiplexer, main control board, intelligent cooling system and power supply system. It uses electronic countermeasures to transmit electromagnetic waves and cut off downlink telephone signals and WiFi signals within a radius of 50 meters. Then mobile phones and wifi cannot work in that area, and people cannot receive or transmit mobile phone wifi signals there. It can interfere with all 2G 3G 4G 5G mobile phone signals and WiFi signals. It has a wide coverage, good interference effect and completely shields all mobile phone signals. Its main feature is ultra-high gain antenna. Traditional gsm jammer usually share a high gain antenna for all channels or use a small gain 5dBi or 9dBi antenna for each channel.
Review Adjustable Box Type Hidden Antenna Wifi Cell Phone Jammer
Excellent design and reasonable price, both of which are very useful. The feature is very powerful, I've used it and I'm very happy with this excellent feature!
Hello, I recently purchased a product from you and I have to say that the quality, shipping and general service quality 5 stars.
The jammer is very convenient and can jam a variety of frequency bands. And turn on or off the appropriate band according to your needs.
This thing works great indoors. It works well in restaurants, but sometimes takes a few seconds of power-on time to clear the signal.
