The eavesdropping device's multifunctional cell phone jammer prevents the operation of all spy bugs and offers reliable protection against spying and eavesdropping. This portable jammer can be taken anywhere, is easy to use and extremely reliable.

A hand signal jammer works on the principle of data transmission between spy devices. Portable jammer contain powerful transmitters (antennas) that emit electromagnetic waves at the frequencies of the receiver of a spy device within a radius of up to 30 m, depending on the configuration of the field and the strength of the device. In this way, the radio frequencies of mobile telephony and mobile internet, wireless internet and bluetooth, GPS tracker location devices, GPS navigation in the car and on the mobile phone, wireless spy cameras and video surveillance cameras are successfully affected. The manual jammer contains multiple antennas, and each module with an antenna can be used as a separate jammer.

Firstly since designed with high power output of 12W for this high power signal blocker to possess up to 30 meters jamming distance depending on the signal strength in the given area. Except as this high power multipurpose signal blocker has 12 antennas so that it can cut the signals of CDMA / GSM, DCS / PCS, 3G, WiFi, 4G LTE, 4G Wimax and WIFIS GPS Lojack jammer at the same time is really strong. what's more, the adjustable button has also been used on this high power jammer so that you can decide the frequency bands jamming and jamming distance according to your real situation.

A GPS jammer describes a device with which the signals of the Global Positioning System (GPS) operated by the US Department of Defense are disrupted or completely blocked. Such a transmitter makes it difficult to receive radio signals properly (for example radio waves, television, mobile communications or the GPS signal). For this purpose, electromagnetic waves are emitted which completely or partially superimpose the signals and waves of the disturbed transmitter and thus render them unusable. A jammer can work on the same or neighboring frequencies, whereby the field strength of the jammer and the type of disturbed waves are important.

Also, the design of the good cooling system for this adjustable heavy duty high power jammer also makes it easy to achieve the 24/7 continuously working goal. For more details of this multi-purpose high power adjustable jammer just come here to gain the useful information.
