On the Ukrainian battlefield, Russia tried to respond to the threat posed by drones by deploying a large number of anti-drone jammers. drone jammer However, it turned out that these radio jammers performed poorly in the face of Ukrainian drone attacks and even became the laughing stock of Ukrainian drone operators. Not only did these devices fail to effectively prevent drone attacks, but they also gave Russian soldiers a "false sense of security" due to design flaws, which ultimately exacerbated their casualties.cell phone jammer

　　The ideal and reality of radio jammers

　　In theory, the principle of anti-drone radio signal jammers is to cut off the communication between drones and their operators by emitting strong radio jamming signals, thereby affecting the control and navigation of drones. Wifi jammer However, the actual battlefield environment is complex and changeable, especially the flexible and diverse flight strategies adopted by Ukrainian drones, and Russian jamming equipment has not adapted well to these changes.GPS jammer

　　A well-known Russian blogger revealed this. He pointed out that the multi-frequency jammers worth $2,400 sold by Russia not only failed to achieve the expected results, but also gave soldiers a false sense of security due to major errors in design and manufacturing, which ultimately threatened their lives. The blogger specifically mentioned that this is not the first time that this device has failed on the battlefield. A few months ago, Ukrainian troops stole a Russian tank equipped with a similar jammer and also found it almost ineffective.

　　Upward antenna and fragile design

　　The blogger conducted a detailed analysis of the design of this radio jammer and pointed out several significant flaws. The first is that the direction of the antenna is not designed properly. An ideal droneGSM jammer should be able to broadcast radio signals in multiple directions, covering a large area, thereby interfering with drones in multiple directions and altitudes. However, most of the antennas of this jammer are fixed upward, which means that it can only cover the situation where the drone flies directly above.

　　Most of Ukraine's FPV (first-person perspective) drones attack from low altitude or from the side, and the upward antenna cannot cope with this flight path at all. As a result, the effective range of the jammer is extremely limited, and its role on the battlefield is greatly reduced. Worse, the fixed design of the antenna means that the device can only deal with drones in a small area directly above the jammer, which is almost impossible on a flexible and changeable battlefield.

　　In addition, the blogger also pointed out the heat dissipation problem of the device. Radio jammers generate a lot of heat when they are working, so an efficient cooling system is needed to ensure the continuous operation of the equipment. However, this jammer is only equipped with a simple fan, and there are no vents on the device casing. This means that the fan cannot exhaust the heat, and the device quickly overheats in a short period of time, and the internal electronic components are damaged. The blogger described this phenomenon as the "blast furnace effect", where the device casing quickly becomes overheated and the operator cannot even touch it.

　　The devastating impact of drones

　　According to analyst Andrew Perpetua, the Ukrainian army destroyed more than 100 Russian armored vehicles in one day, while Ukraine itself lost less than 30. This huge gap is shocking, and drones are undoubtedly a key factor in this result. Perpetua pointed out that more than 70% of Russian vehicles were destroyed by FPV drones, and the precision strike capability of these drones had a devastating impact on Russia's armored forces.

　　FPV drones are not only low-cost, but also highly maneuverable and flexible. The Ukrainian army used these drones in large numbers, which not only effectively dealt with Russia's armored forces, but also highlighted the importance of drones in modern warfare. However, Russia's anti-drone jammers, due to their design flaws and operational problems, were completely unable to deal with this new threat.

　　The failure and reflection of anti-drone technology

　　The blogger severely criticized the Russian manufacturers and social media influencers who designed and promoted these ineffective devices. He pointed out that these people sold inferior products for profit and sacrificed the lives of frontline soldiers. Not only did these devices fail to fulfill their defensive duties, but they also failed at critical moments, resulting in the death of soldiers in combat. Ukrainian drone operators can even "fly over and laugh at these high-tech wastes" when they see that these jammers are ineffective.

　　In the future, if Russia hopes to effectively deal with the threat of drones, it must thoroughly reform its anti-drone technology. First, the design of equipment needs to be more flexible to adapt to the changing flight paths and attack modes of drones. Second, improvements in key components such as cooling systems will be crucial to ensure that the equipment operates stably for a long time. In addition, the Russian military also needs to improve the education of frontline soldiers to help them recognize the limitations of these devices and avoid relying on these technical equipment with serious defects again.

　　Conclusion

　　The anti-drone radio jammers deployed by Russia on the battlefield in Ukraine not only failed to successfully prevent drone attacks, but also became a "fatal trap" for frontline soldiers due to a series of design defects. The failure of these devices exposes Russia's shortcomings in modern warfare technology and provides an important reflection on how to effectively deal with drone threats in future wars. As drone technology plays an increasingly important role on the battlefield, anti-drone technology must undergo a thorough technological innovation and strategic adjustment if it is to truly play a role.
