EW Jammer Q-JMR Block 5 AFS Defense Systems — Overview and Specifications

EW Jammer Q-JMR Block 5 AFS Defense Systems — a modular electronic warfare system designed for effective blocking of enemy UAVs and protection of mobile and stationary positions. Manufacturer: AFS Defense Systems. Product type: EW Jammers > Trench EW Jammers. The Q-JMR Block-X series features a versatile design: devices are convenient for installation on vehicles or deployment at stationary points, they have IP65 dust and moisture protection, allowing outdoor operation in all weather conditions, as well as confirmed vibration resistance for reliable operation during movement and transportation.

Key Features

Programmable modules of proprietary Ukrainian design allow individual adaptation of each device to specific tasks — both in terms of frequency ranges and system operation logic. It is possible to install different module configurations depending on needs.

Three system operating modes: emergency, operational, and expert. Emergency mode activates all modules simultaneously for quick response in critical situations. Operational mode allows the operator to select only the necessary channels, optimizing power consumption and efficiency. Expert mode provides full manual control of each channel with the ability to set precise frequency and bandwidth, allowing for reliable "cover" against enemy UAVs while simultaneously leaving a "window" for the operation of friendly UAVs.

Intelligent control panel displays the status of each channel in real time: operating frequency, module temperature, activity, or malfunction. The panel allows programming modes and quickly changing parameters without connecting to a PC. Remote control and manual control via toggle switches on the front panel are also provided.

Centralized control support: multiple devices can be combined into a single network via the RS-485 interface for synchronous or group control from one point.

*The module covers the entire 400–570 MHz range (or another selected range), but operates simultaneously in a selected band with a width of 25 to 100 MHz. The frequency and width of this band can be quickly changed via the control panel according to the current task.

The Q-JMR Block 5 EW jammer from AFS Defense Systems is ideal for military units and special forces requiring a reliable mobile complex for suppressing enemy UAVs and radio-controlled threats. Its modular architecture, intelligent control panel, and centralized control capability ensure high flexibility of application in field conditions.
