Tallysman TW3870E Antenna

The TW3870E Cover GPS L1/L2 GLONASS G1/G2 Galileo E1 BeiDou B1 Frequency Bands

The Tallysman TW3870E employs Tallysman’s unique Accutenna™ technology which provides truly circular response over the entire bandwidth thereby producing multipath signal rejection resulting in higher positional and timing accuracy. The TW3870E covers the GPS L1/L2, GLONASS G1/G2, and SBAS (WAAS, EGNOS & MSAS) frequency bands. The TW3870E offers excellent axial ratio and a tightly grouped phase center.


  • Accutenna™ Technology
  • Tight Phase Center Variation (PCV)
  • Low noise LNA: 2dB max.
  • Temperature compensating LNAs


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

The OEM TW3870E is 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. 

The TW3870E is REACH and RoHS compliant.
