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.
