Radiolink ANT-M7 RTK rover antenna
The Radiolink ANT-M7 is a compact, weatherproof RTK rover antenna for anyone who wants stable, accurate GNSS positioning in drones, autonomous vehicles, agricultural machinery and other advanced hobby or professional projects.
- High positioning accuracy with a stable phase center
- Support for multiple satellite systems such as GPS, GLONASS, Galileo, BeiDou, QZSS and IRNSS
- Dual interference protection against both in-band and out-of-band interference
- IP67-rated design – dustproof, water resistant and built for outdoor use
- Low weight of just 12.5 g – perfect for drones and mobile systems
Stable RTK positioning for demanding projects
The ANT-M7 is developed for applications where precise positioning is crucial. The passive antenna design with four feeds and eight arms delivers low phase center offset, good directivity and high repeatability – properties that matter in applications such as drone flight, mapping, autonomous vehicles and precision control.
Better reception from multiple satellites
The antenna is designed to provide strong reception even at low elevation angles. This makes it easier for the system to stay in contact with enough satellites, which contributes to more stable measurements and more reliable positioning.
Advanced interference protection
With a pre-SAF filter and a two-stage SAW filter, out-of-band interference is effectively attenuated. This reduces the risk of interference from sources such as radio equipment, 4G/5G masts and high-voltage power lines. The low noise level and the linear LNA design also provide good resistance to interference on the same frequency.
Built for outdoor use
With its IP67 rating, the Radiolink ANT-M7 is protected against dust and water, which makes it well suited for use in the field. It handles tough environments and can be used in everything from hobby builds to more professional applications.
