Overview

The BEITIAN BT series GNSS helical antenna is a compact, IP67-rated, SMA-J active antenna family for multi-constellation GNSS reception (GPS, BDS, GLONASS, GALILEO; model-dependent). Multiple models are available for different frequency combinations such as L1, L1/L2, and multi-band L1/L2/L5, including options that list SBAS, QZSS, and IRNSS support (model-dependent).

Key Features

  • Multi-constellation / multi-frequency working modes (varies by model): GPS, BDS, GLONASS, GALILEO; some models also list SBAS, QZSS, IRNSS, ABAS, and/or L-Band.
  • Helical/spiral antenna structure with SMA interface (SMA-J).
  • IP67 waterproof grade (listed across the series).
  • Small size and light weight (varies by model; weights listed in Specifications).
  • Customization statements provided: can be debugged according to requirements; antennas can be customized according to samples; antennas can be customized according to the concept.
  • Stated performance text: “High precision at the sub meter or centimeter level (Testing in open environments)”.
