DJI Goggles V2 w/ Iflight Crystal antenna patch

This setup combines the industry-leading digital video performance of the DJI FPV Goggles V2 with a popular aftermarket upgrade—the iFlight Crystal Patch Antenna—to create an enhanced immersive FPV experience optimized for long-range and focused flight.

Core Component: DJI FPV Goggles V2

The foundation of this package is the DJI FPV Goggles V2, the central hub for DJI's digital FPV ecosystem. Key features include:

• Stunning HD Low-Latency Feed: Provides an incredibly immersive, real-time view from your drone with a crystal clear 810p/120fps video feed and an ultra-low latency of under 30ms.

• Broad Compatibility: Designed to work seamlessly with the DJI FPV Drone, drones equipped with the DJI O3 Air Unit, and legacy drones using the original DJI FPV Air Unit.

• OcuSync 3.0 Transmission: Utilizes DJI's advanced dual-band (2.4 GHz and 5.8 GHz) technology for a robust, stable, and long-range connection up to 10 km, with automatic frequency switching to avoid interference.

• Integrated Design: Features a built-in battery for up to 110 minutes of cable-free operation, an adjustable headband for comfort, and diopter adjustment lenses (from -8.0D to +2.0D) for users who wear glasses.

• Onboard DVR: Records your flight perspective directly to a microSD card for analysis and sharing.

Performance Upgrade: iFlight Crystal Patch Antenna

This setup is enhanced by replacing one of the stock omnidirectional antennas with a high-gain directional antenna:

• Optimized Signal Focus: The patch antenna concentrates its receiving power in a specific, forward-facing direction, much like a spotlight. This results in a stronger, clearer, and more stable video signal when flying at long range or when the drone is positioned in front of the pilot.

• Increased Range & Penetration: The higher gain and focused signal can significantly extend the reliable range of your video link and improve its ability to penetrate light obstacles like trees.

• Reduced Interference: The directional nature makes it less susceptible to signal reflections and multipath interference, which can cause video flickering.
