Overview
Beitian BT-236 is an RTK GNSS antenna with a quadrifilar helix (four-star) full-frequency design. It is designed for small RTK equipment and supports use with a variety of receivers in surveying/mapping and robotics applications where compact size, light weight, and positioning accuracy are required.
Key Features
- Full-frequency GNSS support: BDS B1/B2/B3/B2a, GPS L1/L2/L5, GLONASS G1/G2/G3, GALILEO E1/E6/E5
- Right-hand circular polarization (RHCP)
- 360° horizontal coverage angle
- Low VSWR: ≤ 1.5 (antenna), output VSWR ≤ 2
- Fixed-hole mounting with 4 × M3 mounting holes (mechanical drawing)
- SMA-J connector with RG178 cable
