Radiolink ANT-M7 - RTK Rover Antenna - Dual Anti-interference of Out-of-band and In-band Interference
- Accurate Directivity
- Multi-star Reception
- Anti-out-of-band Interference
- Anti-in-band Interference
Accurate Directivity
Adopting four-feed eight-arm passive antenna reception, the Radiolink RTK Rover has a low axial ratio, small phase center offset, high positioning accuracy, high phase center stability, great repeatability, and directivity. Suitable for high-speed aircraft.
Multi-star Reception
The four-feed eight-arm passive stereo antenna increases the receiving area and height, greatly improves the low-elevation-angle gain, and has strong low-elevation-angle satellite tracking capabilities, ensuring the measurement system has enough satellites.
Anti-out-of-band Interference
The antenna adopts the design of a pre-SAF filter and two-stage surface acoustic wave filter, with high out-of-band suppression, effectively suppressing out-of-band interference signals, without fear of being close to radio communication equipment, 4G/5G transmission towers, high-voltage lines, etc.
Anti-in-band Interference
Ultra-low noise coefficient, high linearity LNA, and wide dynamic range make the Radiolink RTK Rover achieve strong anti-same-frequency interference ability.
IP67 Protection
Dustproof, waterproof, and corrosion-resistant design, worry-free of the outdoor harsh environment of wind and sun, supports all-weather continuous operation.
Fast Switching between Base Station and Rover
The RTK base station and RTK rover use the same design and firmware. You only need to load different configuration parameters to complete fast switching. The base station and rover use Type-C interfaces, and both ends can be switched freely.
Cost-effective Solution
RTK kit (RTK receiver RTK F9P+ base station antenna ANT-B10+ rover antenna ANT-M7), combined with the PIX flight control series, can be used for the Radiolink automatic driving control system for agricultural machinery vehicles which support 90-degree on-the-spot steering*, or the M435 Heavy Lift Drone, etc. It can provide high-precision positioning within the communication range of the mobile station and is suitable for many professional scenarios such as agriculture, surveying and mapping, inspection, express delivery, takeout, and rescue material delivery.
