Anti-drone technology is considered a vital defensive tool on the battlefield in Ukraine. However, Russian anti-drone jammers have repeatedly proven ineffective.drone jammer Not only did these devices fail to effectively curb Ukrainian drone attacks, but they also gave Russian frontline soldiers a "false sense of security" due to major design flaws, which ultimately led to 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.

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.
Upward antenna and fragile design
The blogger conducted a detailed analysis of the design of this radio jammer and pointed out several significant flaws at the same time. 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.
Worse, the cooling system design of this jammer is extremely simple. Radio jammers generate a lot of heat during operation, and usually require complex heat dissipation mechanisms to prevent the equipment from overheating. However, the Russian jammer is only equipped with a simple fan, and the casing where the fan is located has no vents. This means that the fan not only fails to effectively dissipate heat, but also causes the device to heat up rapidly in a short period of time. The blogger described this phenomenon as the device quickly becoming a "blast furnace", not only the casing is too hot to touch, but the electronic components inside are also degraded or even damaged by the high temperature.
