The Zephyr 3 Geodetic antenna utilizes the Trimble Stealth Ground Plate to function optimally in areas with high multi-path interference. It is protected by weather-resistant materials and a low profile design, so when the antenna is used for a permanent installation, you can count on many years of continuous operation without the need for a radome.

Two antennas are available for geodetic applications:

  1. Trimble Zephyr 3 Geodetic antenna
  2. Trimble GNSS Ti-V2 Choke Ring antenna

Each option is proven to deliver the performance network operators demand to ensure long-term success. In addition, two unique antenna designs provide the flexibility to reach a wide range of operational goals. The choice of what kind of antenna you ultimately choose is driven by your operational needs. Depending upon your priorities, it may become clear that one antenna style is a better fit for your particular application. Here are some questions to consider when choosing the antenna for your project:

  • Are you running a network or performing a geodetic campaign?
  • Does an external organization dictate the antenna style that you must use?
  • Are size and weight important considerations for installation or long-term deployment?
Although there are many different factors to consider and evaluate before making this important decision, Trimble has a solution that will meet your precise needs.

The extended ground plane of a geodetic antenna is intended to stop the multipath signals that come from near or below the horizon. This illustration describes how the innovative technology responds to unwanted multipath signals.
