Overview

This antenna is a three-system seven-band four-arm helical antenna, covering GPS L1/L2, BDS B1/B2/B3, GLONASS L1/L2, widely used in navigation scheduling, tracking monitoring, measurement and control fields. Especially suitable for UAV and many other applications, such as aerial photography, traffic monitoring, remote telemetry, etc., but also can be used in a variety of handheld terminals, high-precision positioning modules.

Key Features

• RTK centimeter-level positioning accuracy

The antenna adopts a four-arm spiral structure to ensure that the error between the phase center and the geometric center of the antenna is small, which can effectively reduce the measurement error caused by the antenna;

• High gain, good performance

the antenna gain is high, the pattern beam is wide, the receiving effect of low elevation signal is good

• Small size, light weight, small equipment load

Dimensions(mm):57*Φ27.5，Weight（g）:≤25

suitable for use on equipment that has requirements for antenna weight, such as the field of drones. The antenna power consumption is small, which can effectively ensure the battery life of the equipment.
