Key Features:

Multi Feed Point Design for Enhanced Performance

• Multi Feed Point Design: This design features multiple feed points, ensuring uniform signal reception and transmission. It reduces phase center variation, improving signal stability.

• Right-Handed Circular Polarization: This polarization type enhances the antenna’s ability to receive right-handed circularly polarized signals from satellites, minimizing errors from reflection and multipath effects.

• Phase Center Stability: The stable phase center improves positioning accuracy by minimizing measurement errors.

High Gain and Excellent Low Elevation Reception

• High Gain: The antenna’s high gain ensures stronger signal reception from satellites, especially over long distances, enhancing overall performance.

• Low Elevation Satellite Reception: With good reception for low elevation satellites near the horizon, the antenna increases the number of available satellites, improving positioning accuracy and system reliability.

Advanced Low Noise Amplifier with Pre-Filtering Technology

• Low Noise Amplifier (LNA): The built-in LNA amplifies weak signals while minimizing added noise, maintaining high signal quality.

• Pre-Filtering Technology: This technology effectively suppresses out-of-band interference signals before amplification, enhancing the system’s reliability and performance.

Durable and Reliable Design

• IP67 Protection: The IP67-rated enclosure ensures the antenna is dust-tight and water-resistant, providing long-term durability for field operations.
