Introduction

ER-MA-08 GNSS Choke Antenna

Introduction

ER-MA-08 GNSS Choke Antenna is a high performance GNSS antenna for base station that covers comprehensive GNSS support: GPS, GLONASS, Galileo, BeiDou as well as L-Band correction service. It is a 2D choke ring antenna with strong multipath suppression performance, specifically designed for applications require absolute positioning accuracy and multi-constellation support.

Features:

High Phase Center Stability: The unique 2D choke ring design of ER-MA-08 ensures an excellent multipath reduction performance. And the antenna features the Harxon patented multi-point feeding technology to achieve greater phase center stability.

Tracking in Challenging Environments: The strong ability to receive low elevation signals with high gain and wide beam width makes ER-MA-08 an excellent choice for tracking visible satellites and provide stable and precision GNSS data.

Strong Anti-interference Performance: The antenna LNA features an excellent out-of-band rejection performance, which can suppress the EMI, providing the stability and reliability of GNSS signals.

More Ruggedized for Long Lasting Durability: The IP67 ruggedized cover is made of Glass Fiber Reinforced Polymer(GFRP) material. The newly designed choke rings are treated with a more robust double treatment for longer lasting durability in harsh environments.
