"Hornbeam" (Hrab) is a tri-band FPV drone video signal detector for the 1.2, 3.3 and 5.8 GHz bands, designed for use in vehicles and at fixed positions.
The detector automatically scans all bands in about 15 seconds: 900–2200, 2800–4070 and 4850–6100 MHz. The 1.2 GHz band is fully available on 24 V power, and on 12 V within 900–1600 MHz. When a video signal is detected, the device turns on the screen, gives audible and LED alerts and shows the received video with signal parameters.
The receiver unit and display can be placed up to 30 m apart, which is convenient for setting up the operator's workstation. Sensitivity and frequency are tuned manually, and friendly frequencies can be ignored. The housing is aluminum, power is 12–28 V (Type-C cable included), and consumption is about 5.3 W in search and 7 W in video mode. A connector for an additional screen is provided. The device only detects signals and is not designed to suppress them.
Key Advantages
- Three bands, full scan ~15 s
- Video, audible and LED alerts
- Receiver and display up to 30 m apart
- Ignoring friendly frequencies
- 12–28 V power, aluminum housing
