TW3870E / TW3872E

The TW3870E (and its housed version of TW3870) employs Tallysman’s unique Accutenna® technology which provides truly circular response over the entire bandwidth thereby producing superior multipath signal rejection resulting in higher positional and timing accuracy. The TW3870E covers the GPS L1/L2, GLONASS G1/G2, Galileo E1, BeiDou B1 and SBAS (WAAS, EGNOS & MSAS) frequency bands. The TW3870E offers excellent axial ratio and a tightly grouped phase center. The higher gain of the TW3870E makes it ideal for use with Trimble’s BD900 series receivers and other receivers requiring higher gain. This antenna sets a new price/performance standard in its category.

Features

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

Benefits

  • 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 (right angle MCX is shown in the drawing). 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 TW3870E is REACH and RoHS compliant.

Mechanical:

Architecture: Twin Dual, quadrature feeds
Size: 60mm diameter, 0.75mm thick
Weight: 75g
Attachment Method: Through hole screws in ground plane
Environmental: REACH and RoHS compliant

Electrical:

LNA Gain: 35dB typ, 32 dB min, each of L1 and L2 Bands
Supply Current: 18mA typ.
Supply Voltage: 2.5 to 16 VDC nominal (12VDC recommended max.)
Noise: 2dB max at 25°C
Axial Ratio, over full bandwidth, both L1 & L2: <1dB typical; 2dB max. at Zenith
