TW7972RXF

The TW7972RXF is a high‑performance, surface‑mount, triple‑band GNSS antenna based on Accutenna® technology, engineered for precision triple‑frequency positioning in demanding environments.

It delivers full coverage across all major global navigation satellite systems, including GPS, QZSS, GLONASS, Galileo, BeiDou, NavIC, and regional SBAS services (WAAS, EGNOS, MSAS, or GAGAN, depending on location). In addition, it supports L‑Band correction services, making it ideal for applications requiring the highest levels of accuracy and reliability.

Advanced Interference Mitigation

As the RF spectrum becomes increasingly congested, GNSS systems face growing challenges from LTE and satellite communication interference. Signals and harmonics from modern LTE bands — including those deployed in North America, Europe, and Japan — can overlap GNSS frequencies and degrade positioning performance. Uplink transmissions from Inmarsat satellite communications further increase the risk of antenna saturation and intermodulation.

To address these challenges, the TW7972RXF integrates Calian’s proprietary XF filtering technology. This advanced filtering architecture effectively suppresses both existing and emerging out‑of‑band signals, including Ligado and LTE transmissions, preventing saturation and ensuring optimal performance of both the antenna and connected GNSS receivers.

Precision Performance Where It Matters

Designed for mission‑critical applications, the TW7972RXF delivers:

• Superior multipath rejection
• Excellent axial ratio
• Linear phase response
• Tight phase centre variation (PCV)

These characteristics are essential for maintaining consistent, high‑accuracy positioning in precision‑driven environments.

Rugged Design for Real‑World Deployment

The antenna is housed in a robust, IP67‑rated weatherproof enclosure, making it suitable for continuous outdoor use in harsh conditions. It offers flexible installation options, including magnetic, adhesive, and screw‑mount configurations, to accommodate a wide range of platforms and use cases.

For optimal performance, a 100 mm diameter ground plane is recommended.

Ideal Applications

The TW7972RXF is particularly well suited for:

• Precision agriculture
• Autonomous vehicle navigation and guidance
• Surveying and geospatial systems
• Industrial and professional GNSS applications where accuracy is critical
