The TW3882E employs Calian’s unique Accutenna® technology and is especially designed for precision dual-frequency positioning, providing dual-band GPS/QZSS-L1/L2, GLONASS-G1/G2/G3, Galileo-E1/E5a, and BeiDou-B1/B2 coverage, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)].


  • Very low noise preamp (< 2.5 dB typ.)
  • Low axial ratio (< 2.0 dB typ.)
  • Tight phase centre variation
  • LNA gain (35 dB typ.)
  • Low current (24 mA typ.)
  • Invariant performance from 2.5 to 16 VDC
  • ESD circuit protection: 15 kV
  • REACH and RoHS compliant


  • Ideal for dual-band PPP and RTK surveying systems
  • Excellent multipath rejection
  • Increased system accuracy
  • Excellent signal-to-noise ratio


The TW3882E is ideal for precision positioning PPP and RTK surveying systems, featured with excellent axial ratios and a tightly grouped phase center variation, and excellent circular polarized signal reception, as well as multipath and out-of-band signal rejection.

The TW3882E 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 wideband LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output.

The TW3882E offers excellent axial ratio, a tightly grouped phase centre variation, in addition to a pre-filter that increases the antenna’s immunity to high amplitude signals, such as LTE and other cellular signals, and near frequency signals, such as WiFi.

The antenna is supplied with a standard 60 mm diameter circular ground plane, with a coaxial cable terminated with your choice of connector (The mechanical drawing shows a right-angle MCX connector). Mounting holes are provided for attachment to larger ground planes. ,
