Introduction

Introduction

Introduction

CM004 is a miniaturized, high precision base station antenna that supports full band for GPS, BDS , GLONASS and Galileo. As it adopts unique choke structure design, the product has the obvious Characteristics of stable phase center, good multi-path suppression, high positioning accuracy, good low elevation receiving effect and so on.

Product Features

1. Submillimeter level phase center, and good repeatability;
2. Small Size, light weight, reliable structure.
3. Adopting the design of Integrated choke ring，multi-path suppression is more effective；
4. Protection level can reach IP67，which can meet the requirements of long-term use under various harsh outdoor environments.
