DB6 All-in-One Portable Cell Phone, GPS, WiFi and LoJack Jammer

The newly upgraded 6-antenna portable signal jammer DB6 can interfere with GSM, DCS/PHS, 3G, 4G, GPS, and GLONASS signals within a small range (1-15 meters). Of course, these are the default interference frequency bands, but you can also customize the interference frequency bands to suit your needs.

This device is not very effective in open spaces or environments near transmission base stations, but it performs well in enclosed environments such as cars or trucks. Therefore, it can be used to block vehicle location signals, such as those from collateral vehicles.
