As the war between Ukraine and Russia continues, the technological confrontation on the battlefield has gradually become the key to victory or defeat. The Ukrainian army has quickly achieved remarkable results with low-cost and high-efficiency drone technology. In particular, drone ground attacks have become an important means for Ukraine to deal with the Russian army.cell phone jammer Against this background, although Russia has invested a lot of resources in the development of advanced anti-drone jamming equipment, the performance of these devices in actual combat is far below expectations, and even exacerbated the losses of the Russian army.GPS jammer
Ineffective jammers: technical flaws exposed
According to the revelations of many bloggers and battlefield observers, a model used by the Russian army costs about $2,400. signal jammer Due to design flaws and improper operation, the multi-frequency jammer not only failed to effectively prevent the attack of Ukrainian drones, but also misled Russian soldiers, making them mistakenly believe that they were protected. This problem exposed the technical shortcomings of the Russian army in the actual application of advanced technology, and also provided more strike opportunities for the Ukrainian army. Wifi jammer
The main problems of this jammer are concentrated on its core design and structure. drone jammer From the orientation of the antenna to the design flaws of the cooling system, the device becomes fragile and unreliable on the battlefield. GSM jammer The designers of the jammer failed to fully consider the diversity and complexity of drones in the actual battlefield, resulting in the complete inability of the device to play a role in actual combat, and even becoming a “fatal trap” for soldiers.
Antenna direction error: unable to effectively defend against drones
The main function of the jammer is to launch drones to The radio noise interferes with the signal connection between the drone and its operator. However, this design has huge flaws in actual use. The blogger pointed out that many jammer antennas used to interfere with low-altitude drones are designed with the wrong direction. These antennas are facing upwards instead of to the side, and low-altitude drones, especially FPV drones (first-person perspective drones), often attack from the side.
FPV drones are difficult to capture by traditional radar or visual means due to their small size and high speed. Therefore, the jammer should have been designed to be more flexible to deal with drone attacks from different directions. However, these jamming devices of the Russian army can only work when the enemy drone flies directly over it, which is almost impossible on a complex battlefield. Therefore, the design of the equipment severely limits its use scenes, unable to adapt to the flexible and changeable attack modes of drones.
This antenna orientation error also means that the interference range of the device is extremely limited, making it difficult to form an effective protective barrier. Even after the enemy aircraft enters the interference range, the interference signal cannot quickly and accurately affect its communication system. The fixed design of the antenna further weakens its flexibility, making it only suitable for specific environments and unable to cope with the ever-changing attack methods on the battlefield.
Equipment overheating: cooling system design defects
In addition to the antenna problem, the cooling system design of the jammer also has fatal flaws. Radio jamming equipment generates a lot of heat when working, and usually requires an efficient cooling system to maintain the stable operation of the equipment. However, the cooling system design of this jammer is too simple and is only equipped with a small fan. The fan lacks sufficient ventilation design and can only circulate hot air in the closed plastic shell, which cannot effectively dissipate heat.
