Tallysman TW2920 Antenna

This configuration includes SMA Female (jack) bulkhead connector, with no cable.

Tallysman introduced the TW2920 antenna for simultaneous reception of L-band correction signals and all of the upper band GNSS signals including GPS L1, GLONASS G1, Galileo E1, and BeiDou B1.

The TW2920 1dB bandwidth covers 1525MHz to 1559MHz for the L band down-link and 1559MHz to 1610MHz for the upper band GNSS.  The LNA of the TW2920 provides 28dB of gain. (A higher gain version with 35dB LNA gain is available as the TW2940. The TW2926 antenna is an unhoused OEM version of the TW2920 with 28dB of gain. Ask us about these.)

The TW2920 employs Tallysmans unique Accutenna technology which provides superior multi-path signal rejection, linear phase response, and tight Phase Centre Variation (PCV). The TW2920 covers GPS L1, GLONASS G1, BeiDou B1, Galileo E1, SBAS (WAAS, EGNOS, GAGAN, & MSAS) and the upper L-Band (1525 1559MHz). This makes it an ideal antenna for use in precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters.


  • Accutenna™ Technology
  • Tight Phase Centre Variation
  • High rejection pre-filter
  • Low noise: 2.5dB
  • Temperature compensating LNAs


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

The TW2920 is housed in a compact, industrial-grade weather-proof, magnet mount enclosure, and is available with a variety of connectors. It is also available without the magnet and an adhesive mount.

The TW2920 is also available with armoured cable. This encases the cable in a corrugated conduit of tough plastic, with a temperature range of -40 to 120°C, excellent chemical resistance, bending stable, high cold impact strength, and UL94HB flammability standard compliant. This extra protection increases the resilience of the antenna.

These are RoHS and REACH compliant.
