DATASHEETTrimble Zephyr 3 Base Antenna
PRECISION BASE ANTENNA WITH MILLIMETER ACCURACY
Integrated with Trimble StealthTM ground plane to minimize multipath andprotected by weather resisting materials, the top of the range Zephyr 3 Baseantenna is the ideal antenna for control work.

Key Features►► Comprehensive GNSS support,

COMPREHENSIVE GNSS SUPPORTThe Trimble Zephyr 3 Base antenna offers full support for current and nearfuture GNSS signals including GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS,
OmniSTAR, Trimble RTX and SBAS.

including GPS Modernization signals,GLONASS, BeiDou and Galileo►► Robust low-elevation satellitetracking►► Large Trimble StealthTM ground planefor multipath rejection

TRIMBLE ZEPHYR 3 BASE►► Millimeter phase center repeatability

In addition to fixed base stations, the Zephyr 3 Base antenna is also suitable asa rover antenna for use in high multi-path environments. The Zephyr 3 Baseantenna’s quality performance and extreme accuracy are achieved throughmillimeter phase center repeatability, robust low-elevation tracking andreduced ground-based multipath interference.

GNSS infrastructure networks►► Additional Iridium and Japanese LTEfiltering►► High signal gain (50dB) for reliabletracking

Key Features:►►

Additional Iridium filtering above 1616MHz allows antenna to be used asclose 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 stealthtechnology with enhanced right hand circular polarization to reduce
multipath interference►►

Advanced LNA (low noise amplifier) to reduce interference by highpower out-of-band transmitters►►50 dB signal gain for reliable tracking in challenging environments andlong cable runs

TRANSFORMING THE WAY THE WORLD WORKS►► Ideal for fixed reference stations and►► Low cross-sectional profile to reducewind loading
