Serhii "Flash" told what a "trench" or small electronic warfare device consists of and how it works (video)

Serhiy Flesh's channel has posted a video about "trench REB" (as Serhiy calls it) or "small REB". The video discusses the technical aspects of the system. In particular, it was noted that the modules purchased in China have adjustable power from 10 W to 100 W. It was also noted that a wider frequency band allows signals to be distributed with a lower density of interference.

The video also mentions the importance of proper power supply and cooling of the modules. To connect the modules, it is recommended to use a voltage converter up to 12 V or 24 V, as well as to install radiators and fans to prevent overheating.

Particular attention is paid to the structure of the trench REB, where it is recommended to use 3 modules per frequency band for optimal system efficiency. It is also important to take into account the peculiarities of using cloverleaf antennas for better performance to counter FPV drones.
