The AU-500 and AU-300 are multi-GNSS timing antennas built for critical infrastructure where service outages cannot be tolerated — such as 5G mobile base stations, TV broadcasting, PTP grandmaster clocks, power grids and business radio systems. The AU-500 is a dual-band antenna (L1/L5) engineered for maximum robustness, while the AU-300 is a single-band (L1) antenna offering excellent cost performance.
Both antennas are designed to let GNSS receivers perform at their full potential even in harsh environments affected by weather and interference, providing safety and security for critical infrastructure systems.
Key Features
Supports worldwide GNSS — L1 and L5 bands (L5 available on AU-500 only).
Integrated ground plane improves sensitivity and reduces interference and multipath; high-quality polymer radome prevents snow accumulation and is waterproof/dustproof to IP67.
Superior out-of-band filtering eliminates interference near 1.5 GHz from 4G/LTE base stations and other radio waves.
Built-in lightning protection compliant with IEC 61000-4-5.
High water resistance to minimise field problems from heavy rain and flooding.
Standard TNC connection.
Highest robustness when combined with Furuno GNSS receivers (GT-100/9001/90/88 & GF-880x series).
Easy, correct installation with the AFB-01 antenna mounting kit.
Optional TVA-05V coaxial lightning arrestor protects both antenna and receiver.
