Third, after replacing the radio frequency module, do not rush to supply power to the police frequency signal jammer. First check whether the frequency of the original radio frequency module is the same as that of the replaced module. If the frequencies of the two modules are different, the corresponding antenna needs to be replaced, otherwise It may damage the RF module and antenna, avoid unnecessary losses, and affect the normal use of the jammer.

Recently, some old customers have called to ask: I purchased our company's signal blocker many years ago, and the model selected at that time, the standard for blocking mobile phone signals only includes the 2G, 3G or 4G of the mobile phone. With the popularity of 5G mobile phones, in addition to buying the latest 5G signal jammer, is there any way to quickly make the signal of the shielded mobile phone also include 5G without abandoning the original old signal jammer?
I, Nanjing Bokang Electromechanical Technology Co., Ltd. can give a quick solution to upgrade to 5G jammers: customers can continue to use the original old signal jammers to keep the original performance of shielding mobile phone signals. In the 5G signal frequency band, 2-3 SMa-818K90 medium-power 5G jammer modules newly developed and produced by our company can be added directly. This 5G blocker module can be freely spliced and combined, independently powered and used, and can block the frequency band only for 5G in the mobile phone signal.
Signal Jammer For SaleIt should be noted that the 5G jammer module added in this way has a single module transmit power of 10-20W, which is greater than the transmit power of the old signal jammer (2-3W). Therefore, customers can Correspondingly, the number of points of the newly added 5G shield is reduced, which is also beneficial to customers to save costs and quickly solve the problem of 5G shielding mobile phone signals.
1. For the actual combat scene of bomb disposal and EOD, the electronic shielding device using the detection frequency sweep method first scans the suspicious frequency points and then starts the interference signal to suppress. There is a time difference. Once the suppression of the remote control signal is not immediate, the consequences are extremely serious. 2. Also for the EOD site, the current remote control technology can achieve wide-band frequency hopping or multi-frequency remote control. Once there is a multi-frequency and frequency-hopping wireless frequency band, the electronic shielding device that detects the frequency sweeping method is scanning. The bandwidth of the interference signal output after the frequency will be widened, and the shielding or interference suppression distance will be greatly reduced. 3. For the application of anti-terrorism scenarios, if terrorists use mobile phone communication during communication, or use mobile phone to detonate remotely, etc., the scanning method of electronic shielding device with detection frequency scanning method cannot achieve all identification and discovery for mobile phones. Even if all the shielding modules are manually turned on, its bandwidth will be stretched too wide, and the shielding distance will be close to 0. Everyone understands: the current mobile phone frequency is from 700MH-4900MH, and there will be 6G in the future... New 4 Antennas Portable Mini GSM/GPS Jammer 4. Some people propose to adopt the electronic signal jammer of the detection frequency sweep method. The total number of broadband power amplifiers and power amplifiers used is small. When interference is required, only the corresponding frequency band needs to be selected for power amplifier output. In this way, the electronic shielding The power consumption of the device is less. However, in actual combat applications, the power consumption of the power supply is not worth mentioning compared to preventing a terrorist incident. The prevention of terrorism is of course the most important thing to ensure the safety of life!
