The TW1322 is a high-performance, cost-effective GNSS antenna designed for GPS/QZSS L1 and SBAS (WAAS, EGNOS & MSAS).
Key Features
- Enhanced Bandwidth: The precisely tuned, single-feed patch element achieves 40% wider bandwidth compared to competitive antennas, supporting 1 dB RHCP received power across the full frequency bandwidth for GPS/QZSS L1 and GLONASS G1.
- Superior Signal Quality: Equipped with a dual-stage Low Noise Amplifier (LNA) and mid-section SAW, the TW1322 ensures excellent axial ratio across the entire frequency range.
- Advanced Filtering: The LNA pre-filter provides robust protection against high-level sub-harmonic signals such as LTE and nearby frequency signals like WiFi.
