RadioLink R9DS Replacement Receiver Antenna

The RadioLink R9DS Replacement Receiver Antenna (Part No: RLKA001013) is an official spare part designed to restore maximum signal performance to your 9/10-channel receiver. Specifically tuned to the 2.4GHz ISM band, this antenna is essential for maintaining the R9DS's impressive 3,400-meter air range. Replacing a damaged or kinked antenna is the most effective way to prevent signal "brownouts" and ensure a stable connection to your transmitter.

Key Features:

• Optimized Signal Clarity: Precisely manufactured to the correct active-element length to ensure peak resonance and sensitivity for DSSS and FHSS spread spectrum signals.
• Diversity Ready: Designed as a direct replacement for the antenna leads on the R9DS. Restoring a damaged lead allows the receiver’s diversity system to function correctly, switching between antennas for the strongest path.
• U.FL (IPEX) Connector: Features a micro-miniature "push-on" connector for a solder-free installation. You can simply snap the new connector onto the receiver board to complete the repair.
• High-Quality Coaxial Cable: Built with robust shielding to minimize interference from nearby electronics like high-power ESCs or video transmitters.
• Generous Length: Measuring approximately 145mm (5.71"), it provides enough reach to route the active tip away from internal components and outside of the fuselage if necessary.

Installation Tip:

The most important part of the antenna is the clear, unshielded tip. Pro-Tip: To maximize range, mount your two antennas at a 90-degree angle to one another (forming a 'V' or 'L' shape). Ensure the unshielded tips are at least 15mm away from any carbon fiber or metal parts, as these materials can "shade" the signal and cause failsafes during flight.

Repair Note: When snapping the new IPEX connector onto the receiver board, align it carefully before applying pressure. A small dab of non-conductive glue (like E6000) can be used to secure the connector in high-vibration environments, such as gas-powered planes or racing drones.
