Overview

The M8HCT-A-SMA is a high-performance, multi-band active quadrifilar helix antenna designed for high-accuracy GNSS applications. It provides concurrent reception across L1, L2, and L5 bands, supporting GPS, GLONASS, Galileo, and Beidou constellations. Featuring an IP67-rated housing and a ground plane independent design, it is ideal for rugged, precise positioning in compact form factors.

Why Choose This Part

This antenna offers exceptional phase center stability and low phase center variation across both azimuth and elevation. Its ground plane independent design allows for flexible mounting on non-metallic surfaces, while the IP67-rated SMA mount ensures reliability in harsh outdoor environments.

Applications

RTK Precision Navigation
Used in Real-Time Kinematic systems requiring centimeter-level accuracy by leveraging L1/L2/L5 multi-band signals.
Autonomous Robotics
Ideal for UAVs and ground robots where a small, lightweight antenna with a stable phase center is required.
GIS Data Collection
Suitable for handheld mapping devices that require high-gain reception without the need for a large ground plane.
Automotive Telematics
Provides reliable positioning for vehicle tracking and fleet management using automotive-grade internal electronics.

Getting Started

Connect the antenna to a GNSS receiver module capable of multi-band L1/L2/L5 reception, ensuring the receiver can provide the required 3V to 5V DC bias at up to 25mA through the coaxial center conductor. For optimal performance, mount the antenna with a clear view of the sky to maximize concurrent constellation tracking.
