We've seen portable drone-jamming devices before, although they tend to take the form of big guns that would be a hassle to carry for long distances. The new clip-on Pitbull, however, is designed to be worn by dismounted soldiers for hours at a time.
Made by Danish firm MyDefense, the Pitbull weighs 775 g/1.7 lb (not counting the battery), and can reportedly run for up to 20 hours in standby or for two hours when jamming.
Users can manually activate the device, causing its internal directional antennas to emit radio signals in the 2.4GHz, 5.8GHz and GNSS (Global Navigation Satellite System) frequency bands up to a range of 1 km (0.6 miles). A not-yet-available optional external antenna covers additional frequencies.
These signals will reportedly disrupt those being used to remotely control an enemy drone, while not interfering with the soldier's own radio communications system.
That said, the device can also be hooked up to MyDefence's recently-released Wingman 103 wearable drone detector, which will automatically cause the Pitbull to start jamming when the control and/or video signals of an incoming drone are picked up. It adds an additional 735 g of weight (1.6 lb), and has a range of up to 2 km (1.2 miles).
