Product Overview

Pro-Grade Precision. Survey-Grade Reliability. The Kalmix ZENITH™ is a high-performance, four-system full-band surveying antenna designed to unlock centimeter-level accuracy for the next generation of autonomous systems. Whether you are building a permanent RTK base station, outfitting a mapping drone, or developing an unmanned ground vehicle (UGV), the ZENITH provides the stable, multi-constellation reception required for professional results.

Powered by an advanced passive antenna element and a high-gain Low Noise Amplifier (LNA), the ZENITH delivers exceptional signal quality even in "urban canyons" or under heavy foliage.

Why Choose Kalmix™ ZENITH?

1. Full-Spectrum Multi-Band Reception

The ZENITH supports all major global constellations including GPS, BDS, GLONASS, and GALILEO. Crucially, it tracks the L1, L2, L5, and E6 bands.

• Faster Fixes: Multi-band support allows for significantly faster RTK "Fix" times.
• PP Ready: E6 and L-Band support enable Precise Point Positioning (PPP) services like Galileo HAS, giving you high accuracy without a local base station.

2. High Gain & Low-Elevation Reception

The antenna's wide beam width and high gain (5.5dBi) ensure that it can track satellites low on the horizon. This is critical for maintaining a stable position in environments with signal obstructions.

3. Professional Interference Rejection

Integrated with high out-of-band rejection, the ZENITH effectively filters out interference from cellular base stations and other radio frequency noise that can cause system instability in industrial or urban settings.

4. Built for Harsh Environments

The ZENITH is housed in a compact, IP67-rated waterproof and dustproof shell. Its ultraviolet-resistant housing ensures long-term durability for permanent outdoor installations, from earthquake monitoring to bridge deformation tracking.
