TW8829

The TW8829 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 TW8829 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.

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

It is highly recommended to use this antenna with a 12cm circular ground plane to improve the gain of the antenna, particularly at the L2 frequency.

The TW1829 is REACH and RoHS compliant.

Mechanical:

Architecture: Twin Dual, quadrature feeds
Size: 47.3mm diameter, 18.3mm thick
Weight: 52g
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
