STA-901 RTK GNSS Antenna | Multi-Band Quadrifilar Helix with SMA-J Connector

Product Content

Short Description

The STA-901 RTK GNSS Antenna is a compact multi-band quadrifilar helix antenna designed for high-precision positioning applications. It supports multiple GNSS constellations, features RHCP polarization, 360° azimuth coverage, an SMA-J connector, and an IP67-rated housing.

Product Overview

The STA-901 is a professional multi-band RTK GNSS antenna designed for high-precision positioning and navigation systems. Its compact quadrifilar helix architecture provides reliable satellite signal reception while maintaining a small mechanical footprint suitable for integrated and external GNSS equipment.

The antenna supports multiple satellite navigation constellations, including GPS, BeiDou, GLONASS, Galileo, and L-band signals. RHCP polarization, 360° azimuth coverage, and an axial ratio of ≤1.5 dB help provide stable reception for positioning applications where antenna orientation and low-elevation satellite signals are important.

With an SMA-J connector, IP67 protection, and an operating temperature range of -40°C to +85°C, the STA-901 is suitable for professional RTK receivers, surveying equipment, UAV positioning systems, robotics, precision agriculture, and other high-accuracy GNSS applications.
