Directional Antenna «Harpina» 5.8 GHz BlueBird
The Harpina 5.8 GHz directional antenna from BlueBird is a professional circularly polarized module specifically optimized for operation in the 5.8 GHz (5800 MHz) frequency band. The antenna's design combines high directivity and compact dimensions, allowing it to effectively shape the radiation pattern for targeted impact on enemy transceiver circuits.
The antenna is available in left-hand or right-hand circular polarization options, enabling system adaptation to specific communication or jamming tasks. With a gain of up to 10.5 dBi and power handling of 50–60 W, the device ensures stable operation even under intense electromagnetic interference.
Purpose: The «Harpina» 5.8 antenna is designed for integration into electronic warfare (EW) systems and is effective for suppressing communication channels of unmanned aerial vehicles operating in the 5.8 GHz band, particularly models similar to DJI Mavic. It is developed for use in various integration configurations:
- mobile systems,
- stationary systems,
- vehicle-mounted options,
- tactical cases and other platforms requiring reliable directional action against drones.
