Directional Antenna "Harpina" 2.4 GHz BlueBird is a highly efficient directional transmit-receive module with circular polarization, designed to operate in the nominal 2400 MHz (2.4 GHz) band. The antenna is available in left or right polarization options, allowing for optimal selection for specific tasks and equipment compatibility. With a gain of up to 10.8 dBi and a power handling capability of up to 50-60 W, this model provides directed intensive radiation for reliable suppression of control and telemetry channels.
Purpose and Application:
The Harpina 2.4 antenna is designed for use in electronic warfare (EW) systems against unmanned aerial vehicles (UAVs) operating in the 2.4 GHz band, specifically for targeting and suppressing signals from DJI Mavic series drones. It is optimized for targeted suppression of control and telemetry transmission channels and can be integrated into various platforms and complexes:
- stationary complexes
- mobile complexes
- transport platforms
- tactical cases and other form factors
