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.
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.
