The Tallysman TW7972 is ideal for precision agriculture, autonomous vehicle tracking, Unmanned Aerial Vehicles (UAV), and other applications where precision is a top priority. The antenna provides superior multi-path rejection and axial ratio, a linear phase response, and tight Phase Center Variation while protecting against intermodulation and saturation caused by high level cellular 700MHz signals.

The Tallysman TW7972 is designed with a dual feed circular stacked patch element. The two signals from the orthogonal feeds are summed in quadrature, pre-filtered in a low loss filter to protect against interfering signals, amplified in high linearity, wide-band LNA, then band-split, tightly filtered and amplified prior to signal recombination at the output.

Key Features:

  • Accutenna Technology
  • Tight Phase Center Variation (PCV)
  • Provides GNSS + INS Solutions at 10Hz Update Frequency
  • Low noise LNA: 2.5dB typ.
  • Temperature compensating LNAs

Key Benefits:

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