Overview

The Beitian BT-208 is a full-frequency, multi-constellation GNSS survey antenna designed for RTK measurement, intelligent inspection, and deformation monitoring. It features a multi-feed-point design with a fully symmetrical antenna structure to help maintain a stable phase center and reduce antenna-pair measurement error. High gain and low VSWR improve reception, including low-elevation signals in challenging environments.

The antenna uses an anti-multipath choke plate and an anti-surge design to help suppress out-of-band strong interference for reliable operation. It is rated IP67 for outdoor use.

Key Features

Full-frequency GNSS reception across multiple systems (GPS, BDS, GLONASS, Galileo, SBAS, QZSS, IRNSS, L-Band)
Multi-feed-point, fully symmetrical antenna structure for stable phase center
Low VSWR and improved low-elevation signal reception
Anti-multipath choke plate and anti-surge design to suppress strong out-of-band interference
IP67 waterproof grade
