Air A21 GPS Antenna

Superior Noise Rejection

Agricultural vehicles and equipment, including aircraft, typically generate electrical "noise" and interference which can compromise the performance of an antenna. The A21™ Antenna is designed to help maintain tracking of GPS and differential correction signals in these types of environments, and in high-dynamic applications where the antenna may be turned on its side.

With a metal base, lower profile, improved multi-path mitigation, and ability to filter out an additional 30 decibels of radio band of frequencies, the A21 Antenna offers superior noise rejection. The antenna will track GPS, SBAS (WAAS, EGNOS, etc.) and L-band signals.

The A21 Antenna also features a TNC connector, which has a threaded coupling interface to ensure a secure connection.

The A21 Antenna was designed for use with the R101™ and R121™ Receivers with AgJunction Crescent® inside.

  • Low profile design with metal base
  • Precise tracking of GPS, SBAS (WAAS, EGNOS, etc.) and OmniSTAR® L-band signals
  • Improved multipath mitigation
  • Superior resistance to radio frequency interference
