Portable Frequency Jammer

The frequency jammer is an irreplaceable device for the execution of security guards, EOD missions, special site secrecy, etc., that is, the frequency jammer can perform full-band electromagnetic interference on the fleet, buildings and areas where suspicious explosives are located, enabling all wireless remote control. The device and wireless communication equipment do not work.

At present, the existing portable frequency jammers almost adopt the external installation method of the antenna, and the number of antennas is usually large. In the case of emergency detonation, it will take a lot of precious time for the detonation personnel to install the antenna on site, and the antenna is easy to be wrongly connected or contacted. Reliable, resulting in equipment damage or poor interference. Moreover, because the antenna is externally connected, the radio frequency connector between the power amplifier and the antenna is exposed, so that the existing portable frequency jammer cannot be designed to be rain-proof and cannot be used outdoors in rainy days.

In addition, the interference frequency ranges of the existing frequency jammers are fixed in advance and cannot be modified on-site. For some occasions, the communication window needs to be reserved or some tasks only need to block certain specific frequency ranges, such as during the EOD process. It is necessary to keep the communication frequency window of the unit, and only need to shield the mobile communication frequency at the scene of the group event. Therefore, these tasks need to adjust the interference frequency range in real time.

Application：

Ø   Used for EOD personnel to transfer or dispose of suspicious explosives;

Ø   Safety and security of important personnel activity places;

Ø   Cut off communication between dangerous persons;

Ø   Confidentiality of important meeting places.

Instrument advantage：

Ø   Digital fast frequency hopping + analog phase modulation method, which can form a seamless electromagnetic shielding wall in the time domain and frequency domain at the same time, shielding any analog and digital wireless remote control devices;

Ø   The interference frequency range can be adjusted in real time on site: equipped with a wired handheld console with a cable length of ≥10 meters. The console is equipped with a 7-inch touchable LCD screen. Through the LCD screen, the interference frequency range can be set on the spot or certain frequency bands can be turned off (for Different tasks or reserved communication frequency bands); see the frequency band allocation table on the LCD screen of the instrument (you can choose to switch or close the frequency bands such as full-band seamless coverage, typical target coverage, drone interception (or 5.8G), etc.).

Ø   Applicable to multi-tasking: For some occasions, the communication window needs to be reserved or some tasks only need to block certain specific frequency ranges. For example, the communication frequency window of the unit needs to be reserved in the process of detonation, and the mobile communication frequency needs to be shielded at the scene of a group event, etc. ;

Ø   Built-in high-capacity lithium battery, built-in high-capacity lithium battery can provide continuous work for ≥ 45 minutes, and can also be connected to external mains (AC220V) to automatically switch to mains.

Ø   Selectable full-band seamless coverage or typical target coverage: effectively shield wireless remote control devices in any frequency band;

Ø   Built-in directional antenna + external omnidirectional antenna combination: no need to connect the antenna manually on site, which greatly saves task preparation time and improves reliability.

Ø   Internal modular design, easy to upgrade and install and maintain.
