Dr-H-3 Handheld UAV Jammer with LCD Display and 500m Range (20W)

A drone can switch between different communication channels within seconds, which means a single-band solution may not cover every situation. The Dr-H-3 drone blocker combines WiFi 2.4G ( 2400-2500MHz), WiFi 5.8GHz ( 5725-5850MHz) and GPS L1/GLONASS L1 ( 1560-1620MHz) interference capability in one compact device, providing broader coverage for common UAV communication systems.

With 20W total output power and a built-in three-in-one 10dBi high-gain directional antenna, the handheld UAV frequency jammer focuses signal energy more efficiently and achieves an effective range of approximately 100–500 meters depending on the environment. It supports popular consumer quadcopters, including models from the DJI Phantom 4 series, Phantom 3 Professional...

The built-in rechargeable battery provides approximately 60 minutes of runtime. An aluminum alloy heat dissipation system enhances thermal performance, while 100% VSWR (Voltage Standing Wave Ratio) overload protection further ensures operational reliability.

An LCD screen on the handle allows users to view key information—such as remaining battery life—at a glance. Users can check the current battery status directly on the screen, eliminating the need to guess how much operating time remains. This convenient design improves the drone defender's ease of use during outdoor operations.
