High-Performance OEM Antenna for Iridium® Satellite Communications
The TW1600 is a cost-effective, OEM-ready antenna module engineered for optimal performance on the Iridium® satellite network. Powered by Calian’s patented Accutenna® technology, it features a dual-feed, passive RHCP (Right Hand Circularly Polarized) design, operating across the 1616 MHz to 1626 MHz frequency band.
Key Features
- Accutenna® Technology: Enhances signal-to-noise ratio for superior Iridium® communication.
- Dual-Feed Wideband Patch: Delivers an exceptional axial ratio across the full Iridium® bandwidth.
- Multipath Rejection: Outperforms single-feed antennas with true circular polarization and reduced signal distortion.
- Integrated Ground Plane: Includes a 35 mm circular ground plane; optimal performance achieved with an additional 100 mm system ground plane or reflective surface (no DC connection required).
Optimized for OEM Integration
The TW1600 is designed for seamless integration into OEM systems. Since antenna performance can be affected by the surrounding environment, Calian offers custom tuning services to ensure optimal performance in your specific application.
