TW4821

The TW4821 employs Tallysman’s unique Accutenna™ technology in a compact magnetic mount antenna covering the BeiDou B1, GPS L1, Galileo E1 and SBAS (WAAS, EGNOS, QZSS & MSAS) frequency band (1557 to 1593 MHz). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection.

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 TW4821 is housed in a compact, magnetic mount, IP67 compliant housings. It is RoHS and REACH compliant.
