TW3740 / TW3742

The TW3740 employs Tallysman’s unique Accutenna™ technology covering the GPS L1, GLONASS G1, BeiDou B1, Galileo E1, and SBAS (WAAS, EGNOS & MSAS) frequency bands (1559 to 1606 MHz). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection resulting in higher accuracy of position and time.

Features

  • Accutenna™ Technology
  • High Gain – 40 dB
  • High rejection SAW filter
  • Low noise LNA
  • Temperature compensating LNAs

Benefits

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

The TW3740 is housed in a through-hole mount, weather-proof enclosure for permanent installations. They are available with either a flat or conical radome in either grey or white. The TW3740 is also available with either a TNC or N-Type connector on the base of the antenna or with a flying lead and a variety of connectors.

L-Bracket or Pipe Mount (part numbers 23-0040-0, 23-0065-0 respectively) are available for non-rooftop installation. They are IP67, RoHS, and REACH compliant.
