TW4721/TW4722

The TW4721 is a compact, wideband GNSS antenna that provides accurate reception for all upper L- band GPS, GLONASS, Beidou, and Galileo signals (L1, G1, B1, B1 BOC, B12, E1) and associated augmentation signals (WAAS, EGNOS and MSAS SBAS). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection resulting in higher accuracy of position and time. This antenna employs Tallysman’s patented Accutenna® technology.

Features

  • Accutenna® Technology
  • High rejection SAW filter
  • Low noise LNA: 1dB
  • Temperature compensating LNAs

Benefits

  • Superior multipath signal rejection
  • Great out-of-band signal rejection
  • Excellent signal-to-noise ratio
  • Consistent response in all operating
    temperatures

The TW4721 is housed in a compact, magnetic or adhesive mount, IP67 compliant housing. The antenna can be ordered without the magnet. In such cases, the magnet is replaced with a plastic plug to provide a smooth under surface. A double sided tape can then be used to mount the antenna.

It is RoHS and REACH compliant.
