300W High Power Prison Network Signal Jammer/Remote Control Signal Blocker




The prison signal jammer is generally a shield designed to meet the management and security requirements of the prison. This shield can be used to select different antennas according to specific needs. You can also provide your coverage environment and pictures. We have your coverage so that we can provide solutions according to your needs. The gain of each antenna is 12-15dBi, and the coverage can reach 150 meters. If your prison management is to prevent the outside world Hazard signals, such as drone signals, GPS positioning signals, and remote-bomb signals, you can choose to block these frequencies. If your prison management focuses on the management of prison inmates, you can focus on the management of cell phone signals GSMCDMAPCSDCS3G2100MHz and Wi-Fi signals. If you are interested in this product, you can contact us.
