Unwave unveils Choven-2 EW system disguised as a roof cargo box

Ukrainian company Unwave has unveiled Choven-2, a multi-channel electronic warfare system designed to protect mobile platforms from drones. Oboronka was the first to note that information about the new product appeared on the company’s website.

The system is built in the form of a roof-mounted cargo box that attaches to standard roof rails and can operate both on the move and in a stationary position. This design allows vehicles equipped with the EW system to retain a civilian appearance.

According to the manufacturer, Choven-2 is equipped with 14 jamming modules delivering 50 W each and covers key UAV control and video transmission bands: 320–1050 MHz, 1.9–2.7 GHz, and 5.1–5.3 GHz, including both horizontal and vertical polarisation. Drone antennas can be oriented vertically, horizontally, or at an angle and may change orientation during manoeuvres, so support for both polarisations reduces the likelihood that enemy UAVs can maintain a stable link.

A diagram published on Unwave’s website shows that Choven operates at 50 W per channel and suppresses FPV drones within a 50–300-metre radius around the vehicle. The communication link between the drone and its operator, which is typically maintained at distances of 2–4 km, is disrupted, while direct impact on the drone in flight reaches up to 300 metres with a vertical coverage angle of 45–60°.

The system’s total output power is up to 1 kW. It runs on 28 V DC and can draw more than 100 amps during operation. With the stated battery capacity, the system can operate for several hours without an external power source.

Among the system’s features, the manufacturer highlights a dedicated DC-DC converter for each module, allowing full power output to be maintained across different battery charge levels and preventing performance degradation during prolonged operation.

The system weighs no more than 100 kg and measures 215×90×45 cm.

Unwave suggests using Choven-2 in combination with the Bashur electronic intelligence detector. Bashur is claimed to offer a detection range of 70 MHz to 6.2 GHz and a detection distance of up to 2 km. Unwave describes an automated scenario in which Bashur detects a threat and triggers jamming, while the operator receives indicators and data on the control console.
