RFD900u antenna cable (u.fl to SMA)
by RFDesign

Establish a secure, high-quality RF connection between your micro telemetry modems and external antennas with the RFDesign RFD900u Antenna Cable. Designed specifically for the RFD900u, RFD900ux, and RFD868ux series telemetry radios, this 150mm pigtail adapter converts delicate onboard u.FL (IPX) micro connectors into a robust, frame-mountable SMA Female bulkhead. This allows drone builders and systems integrators to remotely mount high-gain antennas away from the flight controller to maximize line-of-sight range while protecting sensitive PCB-level RF connectors from crash damage or cable stress.

This high-performance RF adapter is essential for maintaining reliable data links across demanding applications:

• sUAS & Commercial UAV Contractors: Provides a reliable, standardized bulkhead mounting solution for integrating high-power RFDesign telemetry modules into custom carbon fiber airframes and ruggedized ground control stations.

• Long-Range FPV & Fixed-Wing Pilots: Enables the use of standard SMA antennas with modern, ultra-compact u.FL telemetry radios, ensuring maximum transmission range for ArduPilot/MAVLink data networks.

• Educational & STEM Robotics: A perfect hardware component for university engineering labs building custom autonomous networks, allowing students to seamlessly adapt micro-RF boards to standard laboratory test equipment or external antennas.

Installation Tip: u.FL connectors are rated for a limited number of mating cycles. When installing this cable onto your telemetry modem, carefully align the u.FL connector and press straight down until it "snaps" into place. Secure the mated connection with a small dab of electronics-safe silicone or hot glue to prevent the cable from popping off during high-vibration flights.

Key Features:

• u.FL to SMA Conversion: Converts delicate IPX/u.FL PCB-level connections into a standard SMA Female interface for easy high-gain antenna integration.

• Bulkhead Mounting Design: The SMA end features a threaded bulkhead and securing nut, allowing clean, structural mounting through carbon fiber frame plates or plastic ground station enclosures.

• Optimized for RFDesign Modems: Specifically spec'd for RFD900u, RFD900ux, and RFD868ux telemetry modems, but fully compatible with any standard 50-ohm u.FL RF application.

• Flexible 150mm Length: Provides approximately 6 inches of flexible coaxial routing to easily reach from deep within an avionics bay to the exterior of the airframe.
