Trimble Zephyr 3 Base Antenna

Precision base antenna with millimeter Accuracy. The antenna of choice for all RTK reference stations and rover applications in highly reflective environments. Integrated with Trimble Stealth ground plane to minimise multipath and protected by weather resisting materials

In addition to fixed base stations, the Zephyr 3 Base antenna is also suitable as a rover antenna for use in high multi-path environments. Quality performance and extreme accuracy are achieved through millimeter phase center repeatability, robust low-elevation tracking and reduced ground-based multipath interference.

Key Features

Additional Iridium filtering above 1616MHz allows antenna to be used as close as 20m of Iridium transmitter
Additional filtering below 1510MHz allows for antenna placement closer to Japanese LTE cell tower
Trimble Stealth Ground Plane – integrated lightweight stealth technology with enhanced right hand circular polarization to reduce multipath interference
Advanced LNA (low noise amplifier) to reduce interference by high power out-of-band transmitters
50 dB signal gain for reliable tracking in challenging environments and long cable runs
