Description

This extension cable is engineered to provide a low-loss connection between the Holybro H-RTK Helical antenna and the flight controller or GNSS receiver. The 40cm length offers critical flexibility in system design, allowing the high-gain helical antenna to be positioned away from potential sources of electromagnetic interference (EMI) from the drone’s electronics, which is essential for maintaining a strong, multi-constellation GNSS lock.

Constructed with quality coaxial cable and robust SMA connectors, it ensures minimal signal attenuation, preserving the accuracy required for centimeter-level RTK (Real-Time Kinematic) and PPK (Post-Processed Kinematic) navigation. This accessory is a fundamental component for professional UAV builds utilizing ArduPilot or PX4 autopilots where precise geopositioning is mission-critical.

Key Features

  • Precision-engineered 40cm coaxial cable with SMA Female to SMA Male connectors.
  • Optimized for Holybro H-RTK Helical antenna compatibility and signal integrity.
  • Enables strategic antenna placement to minimize RF interference from drone components.
  • Robust connector design ensures a secure, vibration-resistant connection.
  • Essential for maximizing performance in RTK/PPK surveying and mapping drones.

Applications

  • Extending Holybro H-RTK Helical antenna placement on mapping and surveying drones.
  • Improving GNSS signal reception on ArduPilot or PX4-based autonomous UAVs.
  • Integrating high-precision RTK systems into custom multirotor or fixed-wing platforms.
  • Relocating antennas to reduce interference from video transmitters and ESCs.

Frequently Asked Questions

What is the primary function of this Holybro extension cable?

This 40cm cable extends the connection between the Holybro H-RTK Helical antenna and your flight controller's GNSS port. It allows for optimal antenna positioning away from electromagnetic noise sources on the drone, which is critical for maintaining a strong, stable satellite lock required for high-precision RTK and PPK navigation.

Is this cable compatible with other RTK antennas or GNSS modules?

While it uses standard SMA connectors, this cable is specifically designed and tuned for the Holybro H-RTK Helical antenna. Using it with other antennas may work electrically, but for guaranteed performance and signal integrity with the H-RTK system, it is recommended to use it as intended with the matching Holybro antenna.

How do I connect this extension cable to my drone's navigation system?

Connect the SMA Male end of the cable to the SMA Female port on the Holybro H-RTK Helical antenna. The SMA Female end of the cable then connects to the SMA Male port on your flight controller's dedicated GNSS module or a compatible receiver. Ensure all connections are hand-tightened securely to prevent signal loss.
