Compact devices for $450 can warn Russian soldiers about the approach of Ukrainian drones, but not everything is so simple.
In Russia, small businesses assemble drone detectors for the military. A Ukrainian soldier and radio technology expert with the pseudonym Sergiy Flash dismantled this technology on his Facebook page.
The Russian military is supplied to the front with small “pocket” devices that give signals when drones approach, it can be a sound or vibration. The detectors have two antennas operating in the 2.4GHz and 5.8GHz bands. Each band has an on/off button. Next to the antennas there are LEDs indicating the readiness of the device, another one is next to the buttons and shows the battery charge level.

At the bottom of the case is a connector for charging and connecting a data cable. The latter allows you to connect your device to a mobile app to monitor the frequency spectrum. The “insides” are filled with a compound – a polymer resin that protects against moisture.

Sergei Flash called the obvious shortcomings of Russian devices. The cost of the device is about $450, which is too expensive to provide the RF Armed Forces with a sufficient number of detectors in all directions. In addition, they respond to all sources of radio emission in the 2.4 GHz and 5.8 GHz bands, including conventional Wi-Fi signals.
“I believe that the device is assembled on an AD8317 chip. The choice of receiving chips operating in this range is small,” summed up Sergey Flash.
Earlier, Sergey Flash spoke about the creation of portable drone detectors for the Ukrainian military. Developers from the Netherlands, at the request of Ukrainians, redesigned an existing radio signal analyzer and installed new software. Now they are jointly trying to eliminate the identified shortcomings.
Recently, an expert assembled a “trench” electronic warfare system to protect against Russian drones. He spoke in detail about how it works and how Ukrainians can assemble such devices with their own hands. All parts will cost $1000-$1500 depending on the configuration.
