Holybro H-RTK Helical Mount (Vertical Mount)
The Holybro H-RTK Helical Mount (Vertical Mount) is a precision antenna mounting bracket designed specifically for RTK GNSS receivers and communication modules in UAV and robotics applications. Professional drone operators, surveying engineers, and autonomous system integrators rely on this mount to achieve optimal signal reception and system stability during high-precision positioning tasks. This vertical mount configuration solves the critical problem of antenna orientation and electromagnetic interference by providing a dedicated, mechanically stable platform that ensures consistent RTK signal quality and eliminates multipath errors in demanding field conditions.
Product Overview
The Holybro H-RTK Helical Mount utilizes a helical antenna design principle that maximizes circular polarization reception, essential for reliable RTK signal acquisition across varied environmental conditions. The vertical mounting orientation is engineered to maintain optimal antenna elevation angles relative to satellite constellations, ensuring superior lock-on performance and reduced convergence time for centimeter-level positioning accuracy. This mount accommodates standard Holybro RTK receiver modules and integrates seamlessly with popular autopilot systems including Pixhawk, PX4, and ArduPilot firmware ecosystems. The aluminum construction provides electromagnetic transparency while delivering mechanical rigidity that minimizes vibration-induced signal degradation during flight operations.
The vertical mount configuration is specifically optimized for multirotor and fixed-wing platforms where antenna orientation directly impacts RTK baseline resolution and heading accuracy. The helical element geometry provides superior gain characteristics across the L1 and L2 frequency bands used by GPS, GLONASS, BeiDou, and Galileo constellations. Installation involves direct integration with the vehicle frame using provided M3 fastening points, allowing flexible positioning for optimal sky visibility and minimal obstruction. The mount's design eliminates the need for additional RF shielding in most applications, reducing system complexity while maintaining performance specifications across temperature ranges of -20 to 60 degrees Celsius.

How to Use
Begin installation by identifying the optimal mounting location on your UAV or robotic platform, prioritizing unobstructed sky visibility above 15 degrees elevation to maximize satellite signal reception. Secure the Holybro H-RTK Helical Mount using M3 fasteners to your vehicle frame, ensuring the antenna element points vertically upward and remains at least 10 centimeters away from other RF-emitting components such as telemetry modules or video transmitters. Connect the receiver module to your autopilot system using the appropriate serial or CAN bus interface, then configure your flight controller firmware to recognize the RTK receiver by selecting Holybro H-RTK as the GNSS source in your parameter settings.
Prior to field deployment, perform a ground-based RTK initialization test by powering the system and allowing 30-60 seconds for initial satellite acquisition. Monitor your autopilot's status display to confirm RTK fix status transitions from float to fixed, indicating successful baseline resolution. During operation, maintain line-of-sight communication with your base station and verify that atmospheric conditions are favorable, as heavy precipitation or extreme multipath environments may temporarily degrade positioning accuracy. After each mission, inspect the antenna element for physical damage or debris accumulation, and store the system in a dry environment to prevent corrosion of aluminum components.
Frequently Asked Questions
What is the difference between RTK and standard GPS positioning accuracy?
Standard GPS provides accuracy of 5-10 meters under ideal conditions, while RTK (Real-Time Kinematic) positioning achieves centimeter-level accuracy by using a ground-based reference station to calculate and transmit differential corrections to the airborne receiver. The Holybro H-RTK Helical Mount is specifically engineered to receive these correction signals reliably, enabling positioning accuracy of 2-5 centimeters horizontally and 3-8 centimeters vertically when RTK fix is achieved.
Can this vertical mount be used on ground-based robotic platforms?
Yes, the vertical orientation of this mount is equally effective on ground robots, autonomous vehicles, and stationary base stations. The vertical configuration ensures optimal antenna elevation angles regardless of platform type. For ground applications, ensure the antenna maintains clear sky visibility above 15 degrees elevation and position it at least 1 meter away from large metal structures or RF-emitting equipment to minimize multipath errors.
What is the typical RTK convergence time with this antenna?
Convergence time typically ranges from 30-120 seconds depending on atmospheric conditions, baseline distance to the reference station, and satellite constellation geometry. The helical antenna design in this mount provides superior signal quality that generally reduces convergence time compared to patch antenna designs, particularly in challenging environments with partial sky visibility or high ionospheric activity.
Is this mount compatible with non-Holybro RTK receivers?
While this mount is optimized for Holybro H-RTK receiver modules, it can accommodate other standard GNSS receivers with similar form factors and connector types. However, we recommend verifying mechanical and electrical compatibility with your specific receiver model before purchase. Contact our technical support team for compatibility assessment of your particular system configuration.
How do I prevent multipath errors affecting my RTK accuracy?
Multipath errors occur when satellite signals reflect off nearby surfaces before reaching the antenna. Minimize these errors by mounting the antenna at least 30 centimeters away from large metal structures, carbon fiber booms, or RF-emitting components. Ensure adequate ground clearance on aerial platforms, and avoid mounting near reflective surfaces. The helical design of this antenna provides inherent multipath rejection superior to patch antennas, making it ideal for challenging environments.
