Powerful and effective, this portable signal jammer effectively disables any GPS (L1) and mobile phone signals (on the 2G [GSM, CDMA, DCS and PCS], PHS, 3G and 4G LTE 1800 bands) without interrupting any other electronic devices. The highly portable size and one-touch power button allows users to quickly turn the device on or off for instant jamming and un-jamming. Incredibly easy to operate and carry around, this portable signal jammer is both the ideal security and anti-security device and quite simply one of the best we have ever tested.
This is a powerful palm-sized cell phone and GPS signal shield blocker that disables nearly all kinds of cell phone signals, including the 2G (GSM, CDMA, DCS, PCS), PHS, 3G and 4G LTE 1800 bands. The device produces a 2 W radio shield with an effective range of up to 20 meters.
Ideal for meeting rooms, restaurants, concert halls, offices, schools – any place where cell phone use is inappropriate. The GPS L1 jammer blocked the GPS trackers. Keep students from text messaging during tests, and keep unwanted phone calls from disrupting religious services. Usable: private offices, army authorities, police / SWAT authorities, bus and vehicles (imagine how you can finally have a good undisturbed nap), VIP and privacy-sensitive scenarios, etc.
