The top of the range Trimble® Zephyr™ external GNSS antenna contains advanced technology for multipath reduction, outstanding low elevation satellite tracking, and sub-millimeter phase center stability. The Trimble Zephyr 2, Zephyr 2 Rugged, and Zephyr 2 Geodetic antennas offer full support for current and near-future GNSS signals in combination with the rugged durability of each antenna, means the investment in a Trimble Zephyr series antenna will last for many years.


The Trimble Zephyr 2 is a high-performance lightweight GNSS rover antenna optimized for precision RTK applications. The Zephyr 2 GNSS antenna is typically used in roving applications. It minimizes multipath, and offers robust low elevation tracking and sub-millimeter phase center repeatability.


The Trimble Zephyr 2 Rugged Antenna is intended for installations subject to high shock and vibration on the job site. Ideal for drilling rigs, marine vessels, cranes and other vehicle applications, it offers precise positioning with sub-millimeter phase center accuracy.

Key features of the Zephyr 2 and Zephyr 2 Rugged:

  • Optimized for GNSS rover applications
  • Robust low-elevation satellite tracking
  • Minimized multipath
  • Sub-millimeter phase center repeatability


The Trimble Zephyr 2 Geodetic antenna is extremely rugged and ideal for control work. The Zephyr 2 Geodetic is recommended for all base station applications. This antenna is also suitable as a fixed rover antenna for use in high multi-path
environments. The Zephyr 2 Geodetic antenna’s quality performance and extreme accuracy are achieved through sub-millimeter phase center repeatability, robust low-elevation tracking and significantly reduced ground-based multipath.

Key features:

  • Optimized for GNSS base station applications
  • Robust low-elevation satellite tracking
  • Large ground plane for best multipath rejection
  • Sub-millimeter phase center repeatability
  • Ideal for fixed reference stations and GNSS infrastructure networks


The Trimble Zephyr 2 antennas have the ability to track Modernized GPS signals, GLONASS, Galileo, BeiDou, OmniSTAR, and SBAS, the Zephyr 2 antennas are an excellent investment for the future.
