Tallysman TW8829 Dual Band GNSS Antenna

The TW8829 from Tallysman is a dual band antenna with GPS L1/L2, GLONASS G1/G2, Galileo E1, and BeiDou B1 coverage and is especially designed for precision dual frequency positioning for applications where light weight is important, such as for unmanned aerial vehicles. It features a precision tuned, circular dual feed, stacked patch element. The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wide-band LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output. The TW8829 has a strong pre-filter to mitigate inter-modulated signal interference from LTE and other cellular bands.

This antenna is ideal for dual frequency positioning where minimizing weight is important because the 52-gram TW8829 provides excellent axial ratio and tight Phase Centre Variation (PCV), features a precision tuned, circular dual feed, stacked patch element. The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wide-band LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output and also includes an LNA pre-filter that provides enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi. Is housed in an industrial-grade weather-proof enclosure that can be surface mounted via magnet, screws or adhesive material.

Features

  • Accutenna™ Technology
  • Light weight (37g)
  • Low noise LNA
  • Temperature compensating LNAs

Benefits

  • Superior multipath signal rejection
  • Ideal for RTK applications
  • Excellent signal-to-noise ratio
  • Consistent response in all operating temperatures.

 

 

Tallysman recommends using this antenna with a 12cm circular ground plane to improve the gain of the antenna, particularly at the L2 frequency.

The TW8829 is REACH and RoHS compliant.
