TW1829

The TW1829 employs Tallysman’s unique Accutenna technology providing dual band GPS L1/L2, GLONASS G1/G2, Galileo E1 and BeiDou B1 coverage and is especially designed for precision dual frequency positioning where light weight is important.

The TW1829 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 TW1829 has a strong pre-filter to mitigate inter-modulated signal interference from LTE and other cellular bands.

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

The OEM antennas are supplied with a standard 60mm diameter circular ground plane, with a coaxial cable terminated with a connector . Mounting holes are provided for attachment to larger ground planes. Custom tuning and ground plane options may be available, depending on purchase level commitment.

The TW1829 is REACH and RoHS compliant.

Mechanical:

Architecture: Twin Dual, quadrature feeds
Size: 48mm diameter, 12.2mm thick
Weight: 37g
Environmental: REACH and RoHS compliant

Electrical:

LNA Gain: 27dB typ, 26 dB min, each of L1 and L2 Bands
Supply Current: 12 mA typ.
Supply Voltage: 2.5 to 16 VDC nominal (12VDC recommended max.)
Noise: 2.5dB max at 25°C
Axial Ratio, over full bandwidth, both L1 & L2: <2dB typical; 1dB max. at Zenith
