Low-profile Drone Antenna
Four-system full-frequency coverage
This THA‑7609A helix antenna supports four‑system full‑frequency coverage for global navigation satellite signals. It fully covers GPS L1/L2/L5, GLONASS L1/L2, Galileo E1/E5a/E5b, and BDS B1/B2/B3, together with QZSS, SBAS, IRNSS and L‑Band correction services. Such multi‑band, multi‑constellation reception ensures strong signal availability, high positioning continuity, and reliable high‑precision output even in complex environments like urban canyons, low‑elevation angles, and remote areas.
Centimeter-level accuracy
This antenna delivers centimeter‑level accuracy for high‑precision positioning. Supported by stable phase center performance, low deviation, and full‑frequency multi‑GNSS reception, it provides reliable centimeter‑grade positioning results for surveying, mapping, UAV surveying, and other high‑precision applications.
Low height and easy to integrate
Low height and easy to integrate. The THA‑7609A features a compact, low‑profile structure with a miniature form factor of just φ43.6×40.8mm and a weight as low as 30.5g. Its slim design allows flexible embedded installation in UAVs, mapping devices, and mobile platforms, while the bottom screw‑mounting structure ensures stable and reliable fixation. The lightweight and low‑height construction greatly reduces payload load, improves flight endurance, and supports seamless integration into space‑limited systems.
Wide working band and high reliability
The THA‑7609A supports a broad operating frequency range covering all major GNSS bands and L‑Band correction services, ensuring stable signal reception across global navigation systems. It features excellent out‑of‑band rejection, low noise figure, and stable electrical performance to resist electromagnetic interference. With an IP67 protection rating, wide temperature tolerance from ‑40℃ to +70℃, and 95% non‑condensing humidity resistance, this antenna maintains consistent performance in harsh outdoor and airborne environments, delivering long‑term durability and highly reliable positioning for mission‑critical applications.
Excellent satellite reception
Equipped with advanced D-QHA technology, the THA‑7609A significantly enhances low‑elevation tracking performance and maintains stable signal lock even in challenging environments. It supports full multi‑GNSS constellation and wide‑band reception, delivering strong omnidirectional signal capture, high gain, and low axial ratio. This ensures continuous, clear satellite signal reception, improved positioning availability, and reliable navigation output for UAV, surveying, and remote sensing applications.
