Dome EW Systems

A dome EW system is a stationary or mobile system that creates a protective radio frequency field — a jamming "dome." Its purpose is to block control, navigation, and data transmission signals of approaching FPV drones. Such an anti-drone EW dome is ideal for covering warehouses, headquarters, and logistics points.

Purpose of Dome EW Systems

The main task of a dome EW system is to create interference that prevents drones from operating within the system's range. This allows for:

  • Protecting military facilities, command posts, ammunition depots, and logistics hubs;
  • Preventing enemy fire adjustment that relies on aerial reconnaissance;
  • Complicating drone navigation by blocking GPS/GLONASS signals;
  • Suppressing communication channels between the operator and the drone.

Principle of Operation of Dome EW Systems

A dome EW system operates on the principle of active jamming of enemy radio signals. The system analyzes the airwaves, detects drone control signals, and instantly generates broadband interference on the required frequencies. Thanks to radar and monitoring systems, dome systems can act preventively — that is, create a jamming "umbrella" even before a threat approaches.

Main Components of EW System Design

A dome EW system consists of:

  • Antenna arrays for circular or sectoral coverage;  
  • Transmitters and interference generators operating in a wide frequency range;  
  • A control system that automatically changes jamming parameters depending on the situation;  
  • Power supply, usually with backup sources (generator or battery).  

Design Characteristics

  • Wide frequency spectrum: GPS, GLONASS, Wi-Fi, 4G, 5G.  
  • Automatic detection and adaptation to drone types.  
  • Compatibility with other defense systems.  
  • Ability to localize the signal of the control source.  

Advantages of Dome EW Stations

  • Scalability: can cover both small points and large infrastructure facilities.  
  • High power and multi-channel capability.  
  • Full autonomy — automatic operation without constant operator control.  
  • Versatility — application in field conditions, on rooftops, in shelters, etc.  
  • Intelligent algorithms allow operation even in complex electronic warfare conditions.  

How to Choose a Dome EW System

Before buying a dome EW system in Ukraine, consider:

  • Type of object and threat (FPV, GPS drones);  
  • Power and coverage range;  
  • Installation conditions (roof, field, shelter);  
  • Need for integration or autonomy.  

At Flash Army, you can buy a dome EW system with warranty and service. Our specialists will help you choose and buy a dome EW system in Ukraine at a fair price, including anti-drone EW systems and professional dome-type EW systems. The price of a dome EW system depends on the range, number of frequencies, and form factor — contact us for a consultation.

Frequently asked questions about products in this category Dome EW Systems

A dome EW jammer is an electronic warfare system that creates a protective zone around an object based on the "dome" principle. It is designed to block UAV control and data transmission channels within a defined radius. Such systems are used to protect positions, equipment, warehouses, and stationary objects.
The system creates radio interference that disrupts communication between the drone and its operator or navigation systems. As a result, the UAV may lose control, hover, change its route, or enter emergency mode. The specific reaction depends on the drone's settings and the type of signal.
The average range of a dome EW jammer is typically from 1 to 10 km, depending on the system's power and environmental conditions. In open terrain, the coverage area may be larger, while in built-up areas or complex terrain, it may be smaller. Actual performance depends on frequencies and equipment configuration.
Dome EW jammers typically support 4 to 16 simultaneous jamming channels, depending on the model. Each channel is responsible for a separate frequency band, allowing for coverage of various signal types. The number of channels affects the system's ability to counter multiple threats simultaneously.
The operating time of a dome EW jammer typically ranges from 6 to 24 hours, depending on the power source and load mode. In stationary conditions, systems are often connected to a permanent power supply, allowing for unlimited operation. Autonomy also depends on the power and number of active channels.
Dome EW jammers typically operate from a 220V mains supply or generators and can also use backup batteries. Active cooling systems with fans or combined solutions with radiators are used for cooling. The type of cooling system is determined by the equipment's power and operating duration.
Most commonly, the 2.4 GHz, 5.8 GHz, 868 MHz, and 915 MHz bands, used by most drones, are suppressed. In some configurations, GPS navigation frequencies within approximately 1.2–1.6 GHz are additionally blocked. The specific list depends on system settings.
The effectiveness of dome EW depends on the system's power, proper deployment, and level of countermeasures. Under favorable conditions, such systems can significantly limit the operation of FPV drones and reconnaissance UAVs within the coverage area. The result is determined by range, frequencies, interference density, and tactical use.
