TW2920 恶劣环境工作

The TW2920 employs Tallysman’s unique Accutenna™ technology which provides superior multi-path signal rejection, linear phase response, and tight Phase Centre Variation (PCV). The TW2920 covers GPS L1, GLONASS G1, BeiDou B1, Galileo E1, SBAS (WAAS, EGNOS, GAGAN, & MSAS) and the upper L-Band (1525 – 1559MHz). This makes it an ideal antenna for use in precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters.TW2920 TW2920

Applications 应用

• High Accuracy & Mission Critical GNSS  高精度与紧要任务

• Precision Agriculture, Mining & Construction 精确农业,矿山与建筑
• Military & Security 军用与保安

Features

  • Accutenna™ Technology
  • Tight Phase Centre Variation
  • High rejection pre-filter
  • Low noise:  2.5dB
  • Temperature compensating LNAs

Benefits

  • Superior multipath signal rejection
  • Great out-of-band signal rejection
  • Excellent signal-to-noise ratio
  • Consistent response in all operating temperatures

The TW2920 is housed in a compact, industrial-grade weather-proof, magnet mount enclosure, and is available with a variety of connectors. It is also available without the magnet and an adhesive mount.

The TW2920 is also available with “armoured” cable. This encases the cable in a corrugated conduit of tough plastic, with a temperature range of -40 to +120C, excellent chemical resistance, bending stable, high cold impact strength, and UL94HB flammability standard compliant. This extra protection increases the resilience of the antenna.  天线线缆加波纹管可选,宽温达-40 至+120C,耐化学性,耐折弯,高耐寒性, 防火等级符合UL94HB标准。额外保护套增强天线弹性。

They are RoHS and REACH compliant.
