Choke Ring Gnss Antenna | Mini Choke Ring Antenna

Overview

The Harxon HX-CGX611A is a high-performance GNSS base station antenna designed for absolute positioning accuracy and multi-constellation support. It provides comprehensive GNSS coverage including GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS, SBAS, and L-band correction services.

Featuring a mini choke ring design, the HX-CGX611A delivers excellent multipath suppression and stable signal tracking, making it ideal for GNSS base stations, reference stations, CORS networks, and other high-precision positioning applications.

Key Features

High Phase Center Stability

HX-CGX611A adopts unique choke ring structure design which delivers extraordinary multipath suppression performance. It also features Harxon patented multi-point feeding technology to achieve the repeatability of phase center and geometrical center.

Excellent Signal Tracking in Challenging Environments

HX-CGX611A excels its signal tracking performance thank to its high gain and wide beam width for directional diagram, which ensures ideal satellite signal reception.

Powerful Anti-interference Performance

The LNA of this antenna features an excellent out-of-band rejection performance, which can suppress unwanted electromagnetic interference(EMI) and avoid many other interferences.

Mini Design with Ruggedization and Durability

HX-CGX611A is a ruggedized and durable mini choke ring antenna that built into an IP67 rating housing with multiple protection designs to withstand exposure against dust, rain, splash or sunlight.
