Overview
The Beitian BT-200S is a full-band GNSS transmitting antenna designed for satellite navigation signal distribution and calibration-style differential measurement setups. It supports GPS L1/L2/L5, GLONASS L1/L2, and BDS B1/B2/B3, with 360° horizontal coverage, RHCP polarization, and an IP67-rated enclosure for outdoor deployment.
Key Features
- Full-band GNSS support: GPS L1/L2/L5, GLONASS L1/L2, BDS B1/B2/B3
- 360° horizontal coverage angle for omnidirectional signal capture
- Right-hand circular polarization (RHCP)
- 50 Ohm port impedance
- TNC-K connector interface
- Outdoor-rated structure: IP67 waterproof grade, 95% non-condensing humidity tolerance
- Operating temperature: -45°C to +75°C; storage temperature: -55°C to +85°C
- Mechanical interface: 5-8"/11UNC
- UV material: UV-resistant PC material (sun-proof/UV-resistant and intended to resist discoloration during long-term outdoor use)

Details

Built for full-band GNSS signal distribution, the BT-200S combines RHCP polarization, 360° coverage, and an IP67 enclosure for outdoor deployments.


Full-band transmission helps stabilize satellite navigation signal coverage for calibration-style differential measurement setups.


Installation is straightforward with a 5/8-11 UNC threaded mount, UV-resistant PC housing, and a TNC-K connector for 50-ohm GNSS systems.

A TNC-K interface and standard threaded mount support clean integration into indoor distribution layouts that relay GNSS signals from an outdoor receiving antenna.



Choose a single-antenna set or a package with BT-M110SLD and a 5 m TNC-to-SMA cable, depending on your setup requirements.
