Beschreibung

SR-303 is a full‑frequency quad‑helix antenna designed for GPS L1/L2/L5, BDS B1/B2/B3, GLONASS L1/L2, and GALILEO E1/E5a/E5b. With compact size and lightweight construction, it is widely used in navigation dispatch, tracking monitoring, and telemetry. The quad‑helix design provides stable phase center, high gain, and excellent low‑elevation reception — making it especially suitable for UAVs, handheld terminals, and high‑precision positioning modules.

Key features
  • Quad‑helix design: stable phase center · improves measurement accuracy
  • High gain: wide beamwidth · excellent low‑elevation reception
  • Low noise amplifier: high out‑of‑band rejection · low power consumption
  • Compact & lightweight: Φ28×58.5mm · ≤17g
  • Multi‑GNSS: GPS, BDS, GLONASS, GALILEO
  • IP67 waterproof · wide temperature range

Applications: UAV navigation, aerial photography, traffic monitoring, remote telemetry, handheld terminals, high‑precision positioning modules, RTK systems.
