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)”.

Details

Choose the right BT-series model by comparing supported GNSS bands, size, power range, and waterproof rating across the lineup.

Customization is available for firmware/debug settings and antenna variations to match your sample or design concept.

An SMA-J active helical design supports multi-constellation reception, with frequency coverage varying by model.

IP67 sealing, compact cylindrical housing, and an SMA interface make the antenna suitable for demanding outdoor GNSS installs.


Gain spectrum test plots provide a quick reference for how different BT-series variants perform across their intended bands.

Common use cases include hydrographic surveying and geodetic fieldwork where stable satellite reception is required.
