Trench EW Systems

Trench EW Systems

Trench EW is a stationary electronic warfare system designed to protect Ukrainian Armed Forces positions from drones, navigation signals, and enemy communications. Such devices are placed directly in trenches, dugouts, observation posts, or near field infrastructure.

Purpose of Trench EW Systems

The main task of trench EW is to create an active protection zone around a position. The device:

• jams UAV control signals;  
• blocks data transmission between drones and operators;  
• creates interference for satellite navigation;  
• protects command posts and personnel from aerial surveillance.  

How Does Trench EW Work?

The principle of operation is simple: the system detects the frequencies on which drones or other communication devices operate and creates a strong radio pulse in the corresponding range. This leads to:

• loss of communication between the drone and the pilot;  
• disruption of coordinate transmission;  
• reduced targeting accuracy or complete disabling of the drone.  

Some models are equipped with intelligent signal analysis algorithms, allowing them to automatically adapt their operation to a specific threat.

Technical Specifications of Trench EW Stations

Range — up to 1500 meters  Jamming formats — GPS, 2.4G, 5.8G, LTE, GSM  Power supply — from external batteries or generator  Startup time — 5–10 seconds  Protection — IP65 or higher  Weight — 5–10 kg (depending on model)
These stations are easily mounted in shelters, operate in dusty, humid conditions, withstand temperature fluctuations, and do not require special maintenance.

Key Advantages of Trench EW

• Stable operation in field conditions  
• Camouflage and mobility  
• Effective jamming of kamikaze and FPV drones  
• Autonomous operation for up to 24 hours  
• Rapid response to threats  
• Intelligent approach to radar

These systems are already actively used on the front lines and have proven their effectiveness in real combat conditions.

How to Choose Trench EW?

Before buying trench EW, pay attention to:

• the types of signals the system jams;  
• the operating range (for trench format, 800–1500 m is optimal);  
• the possibility of autonomous operation;  
• resistance to external factors.
