Overview
Beitian BT-564 is a foldable quadrifilar helical GNSS antenna with an SMA-J connector, designed for RTK/UAV navigation and other GNSS positioning receivers that need stable multi-constellation signal reception in a compact form factor. It supports GPS, BDS, GLONASS, GALILEO, SBAS, QZSS, and IRNSS signal bands and provides 360° horizontal coverage.
Key Features
- Foldable design (up to 90°) to reduce volume
- Multi-system, multi-band reception: GPS L1/L2/L5; BDS B1/B2/B3; GLONASS L1/L2/L3; GALILEO E1/E5a/E5b/E6; SBAS L1/L5; QZSS L1/L2/L5/L6; IRNSS L5
- 360° horizontal coverage angle
- Right-hand circular polarization
- Low power consumption: operating current <50 mA (3.3–12.0 V)
- Compact and lightweight: antenna weight ≤28 g

Details
Insert the BT-564 foldable quadrifilar helical antenna for stable multi-band GNSS/RTK reception in a compact form factor.
Multi-constellation, multi-band support helps maintain reliable positioning across GPS, BDS, GLONASS, Galileo and more.
Designed for projects that need consistent positioning accuracy without the typical pitfalls of single-frequency reception.
360° horizontal coverage and right-hand circular polarization support stable signal tracking in UAV and RTK workflows.
The antenna body folds up to 90° to reduce overall volume when packing small UAV or handheld kits.
Low power draw and a built-in LNA support strong reception while keeping overall weight minimal for mobile platforms.
Clearance-friendly dimensions before and after folding make integration easier on tight airframes and compact enclosures.
Choose a multi-band design for better satellite coverage and fewer positioning interruptions in demanding environments.
One BT-564 antenna is included, suitable for drones, RTK receivers, and compact GNSS-enabled devices.
