AU-300 single band antenna for high robustness and excellent cost performance

This antenna is designed to enable GNSS receivers to perform at their full potential even under harsh environments such as weather and interference. They provide safety and security for critical infrastructure systems such as 5G mobile base stations, TV broadcasting, PTP grandmaster clocks, power grids and various types of business radio systems, where service outages are not tolerated. AU-300 is a single-band antenna supporting only L1.


  • Single antenna (L1)
  • Support for global and regional satellite systems
  • High gain, low noise
  • Ideal for time synchronization applications
  • Superior out-of-band filtering
  • Built-in lightning protection – compliant with IEC 61000-4-5
  • IP67, CE, FCC & RoHS 2 compliant
