We all know that a country ’s army is like a human heart. National security depends on the troops and their soldiers, although in the information age, more and more countries adopt high-tech development. Therefore, it is necessary to ensure the safety of the troops, especially the special forces. Of course, high technology may be more useful than humans, and the latter is better. In order to achieve this goal, the 80W portable design high-power wireless explosion-proof jammer has a good function of cutting off up to 5 frequency bands, which can contribute to the country and the military.
As a high output power telephone drone jammer, a JFC-021-0110 has a high blocking capacity to prevent 2G: CDMA 851-894 MHz, GSM 925 -960 MHz, DCS / PCS 1805 -1990 MHz; 3G: 2110 -2170 MHz; 4G: 725 -770 MHz; 4G: 2345-2400 MHz or 2620 -2690 MHz. This almost covers mobile phones, growing 4G mobile phones, previous 3G mobile phones and long-lasting 2G mobile phones … On the other hand, it shows that the “powerful function” of the phone jammer covers a range up to 100 meters It also depends on the current environment, target distance and obstacles. Cell phones in this area will be blocked by cell phone jammers.

A pastor named Madonna said that at first he posted a poster asking people to turn off their phones, but when the buzzing and dings continued, even at the funeral. “What really annoys me is that when it was first started, people would switch off their phones awkwardly; now they are holding their hands on the receiver and continue talking,” he said.
