To face the challenge of side effect of using mobile phone like tapping/detonate bomb/interrupt important signal in hot zone and sensitive area/trigger gasoline station explosion etc. things, we invented JM series mobile phone Jammer. It’s very useful at places where using mobile phones is prohibited such as government meeting, military hot zone, finance transaction hall, court, police department, prison, battle field, command center etc.

Features：

1) 4 Channels can efficiently jam for every kind of mobile signal from CDMA, GSM, DCS, PHS and 3G.

2) It only jams the signals from mobile phone and doesn’t affect any other electronic devices.

3) Slow start – up circuit can avoid sparkling caused by mechanical switch. Therefore it’s very useful in sensitive area like gasoline station or arsenal.

4) Mini portable version is very light and very easy to carry. It used built-in charge battery. The battery can work 2-3 hours without AC power.
