REW04 EW Jammer, 4 Bands, 200-5800 MHz — Kalmius Tech

The professional electronic warfare jamming system REW04 from Kalmius Tech is designed for effective radio communication blocking across a wide frequency range of 200-5800 MHz. The REW04 model demonstrates high versatility and adaptability: the original description also mentions the REW08 modification for in-cabin installation with quadrifilar antennas and extensions for mounting on a vehicle roof. The casing can be made of plastic for reduced weight or metal for increased durability and shielding, with active cooling provided for stable operation under intensive use.

Specifications

• Possible frequency range: 200-5800 MHz
• Tactical range: 50-150 m
• Number of jamming channels: up to 4
• Power supply: 12 V, up to 40 A
• Power consumption: up to 100 W per channel
• Casing material: plastic or metal
• Weight: 5 kg

Features and Purpose

The REW04 is designed for tactical and operational suppression of radio signals in various conditions: protecting vehicle interiors, creating a "dead zone" for remote control, preventing data transmission, and enhancing security during special operations. Active cooling ensures stable operation under load, and the ability to power from a 12V on-board network (car battery) or an external PS12 charging station (sold separately) makes the device mobile and convenient to use.

Package Contents

• Radio jamming and control unit, 1 pc
• Power cable with terminals and alligator clips, 1 pc, 3 m
• Remote power disconnect switch, 1 pc, 2 m
• Antennas with magnetic and/or screw mounting: cloverleaf or quadrifilar, 1 pc per channel
• Coaxial antenna extensions, 1 pc per channel, 2.5 m

The set of components allows adapting the system to specific tasks: choosing the type of antennas (cloverleaf or quadrifilar), using extensions to mount antennas on the roof or other external points, and quickly disconnecting power using the remote control. A weight of approximately 5 kg and casing options (plastic or metal) allow optimizing the balance between mobility and electronic protection.

Product category: EW Jammers › Vehicle EW Jammers. Manufacturer: Kalmius Tech. Model: REW04 (the text also mentions the REW08 variant for in-cabin installation with quadrifilar antennas).

Other technical parameters: a tactical range of 50–150 m ensures localization of jamming effects in the area of operational necessity; power consumption up to 100 W per channel with a maximum of 4 channels meets the requirements of powerful electronic warfare systems; 12 V, up to 40 A power supply ensures compatibility with the on-board electrical systems of most vehicles. The REW08 modification with quadrifilar antennas and extensions allows installing the antenna assembly in the cabin or extending it to the roof to optimize coverage and jamming directionality.
