RadioLink AT10II Replacement Transmitter Antenna

The RadioLink AT10II Replacement Transmitter Antenna (Part No: RLKA001034) is the official factory spare part designed to maintain the long-range, high-fidelity signal of the AT10II 12-channel system. Because the AT10II is often used for long-range FPV and professional UAV missions, even minor physical damage to the antenna can result in reduced signal penetration and dangerous failsafes. This replacement restores the full 4km (air) range of the system.

Key Features:

• DSSS & FHSS Compatibility: Specifically tuned to handle RadioLink's unique hybrid spread spectrum technology, ensuring high anti-interference performance across 12 channels.
• Precision Swivel Mechanism: Features a reinforced 90-degree tilt and 360-degree rotation joint, allowing for optimal signal polarization during flight.
• Internal IPEX Connection: Comes with a pre-installed shielded coaxial cable and a micro IPEX (U.FL) snap-on connector, making the replacement process solder-free.
• OEM Engineering: This is an original RadioLink part, matching the specific impedance ($50\Omega$) and gain requirements of the AT10II’s internal RF circuitry.

Installation & Safety Guide:

Replacing the antenna on a 12-channel radio requires precision. Pro-Tip: When opening the AT10II casing, be mindful of the toggle switches on the top corners, as they can easily catch on the shell. When snapping the new antenna lead onto the RF board, ensure the connector is perfectly centered; pushing at an angle can flatten the tiny center pin on the board.

Signal Optimization Tip:

For maximum range when flying aircraft at high altitudes, the side of the antenna should face the model. Pro-Tip: Fold the antenna to a 90-degree angle so it is parallel to the ground. This ensures the "donut-shaped" signal radiation pattern is oriented vertically, providing the best coverage for long-distance flight. Avoid pointing the tip of the antenna directly at your drone.

Crucial Warning: Do not power on the AT10II while the antenna is disconnected or the case is open. Running the transmitter without the load of an antenna can cause the RF power amplifier to burn out within seconds.
