TW3870E、TW3872E双频天线 35dB增益-Gatewing无人机采用

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, and SBAS (WAAS, EGNOS & MSAS) frequency bands. The TW3870E offers excellent axial ratio and a tightly grouped phase center. This antenna sets a new price/performance standard in its category.

支持GPS L1/L2, GLONASS G1/G2, 北斗B1,Galileo E1和SBAS (WAAS, EGNOS & MSAS)，75克重。

Features特点

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

Benefits优点

  • Superior multipath signal rejection           多路径抑制
  • Ideal for RTK and PPP applications     RTK与单点精密定位应用理想天线
  • Excellent signal-to-noise ratio                                                极佳信噪比
  • Consistent response in all operating temperatures         全温侯连续响应

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.
