LNY4N03A is a Mini Choke Ring Antenna capable of tracking all satellite constellations, GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS, SBAS as well as L-Band correction service, and is multi-frequency. This antenna has a high anti-interference function, making it perfect for operations in harsh environments. In addition, LNY4N03A have high gain even with low elevation signals tracking.

Product Features

MINI Choke ring antenna

1. High Phase Center Stability: The LNY4N03A antenna adopts a unique ring structure that offers outstanding multipath suppression performance for satellite signal tracking. The stability of this antenna reaches submillimeter values, ideal for monitoring and permanent GNSS networks.

2. Excellent Signal Tracking in Challenging Environments: LNY4N03A excels its signal tracking performance thank to its high gain and wide beam width for directional diagram, which ensures ideal satellite signal reception.

3. Powerful Anti-interference Performance: The antenna has high immunity to interference and is ideal for operation in harsh environments.

4. Mini Design with Ruggedization and Durability: The LNY4N03A is a ruggedized and durable mini choke ring antenna designed to protect the interior from dust and water (IP67). This antenna has excellent performance in a small size, with a diameter of only 185mm and a low weight of ≤2.5Kg. This allows easy installation compared to standard Choke Ring antennas, which are larger and heavier.
