TW1721/TW1722

The TW1721 is a compact, wideband GNSS antenna that provides accurate circular reception for all upper L- band GPS, GLONASS, Beidou, and Galileo signals ( L1, G1, B1, B1 BOC, B1-2, E1) and associated augmentation signals (WAAS, EGNOS and MSAS). This antenna employs Tallysman’s patented Accutenna® technology.

The TW1721 provides truly circular response across the full frequency of the antenna providing superior multi-path signal rejection resulting in higher accuracy of position and time.

Features

  • Accutenna® Technology
  • Smallest high accuracy OEM L1 antenna
  • High rejection SAW filter
  • Low noise LNA: 1 dB typ
  • Temperature compensating LNAs

Benefits

  • Superior multipath signal rejection
  • Ideal for wearable devices
  • Improved carrier phase linearity
  • Excellent signal-to-noise ratio
  • Consistent response in all operating
    temperatures

OEM antennas are easily detuned by the local environment. Tallysman offers custom tuning services for optimized integration into OEM end-user modules.
