Description

The TrueRC X-AIR 5.8 Mk. II antenna represents a significant miniaturization of the proven X-Air platform, reducing its footprint by approximately 75% while maintaining high-performance characteristics. Its advanced phased array elements are engineered to deliver a high axial ratio, which is critical for maintaining Left Hand Circular Polarization (LHCP) purity. This results in cleaner video signals with reduced multipath interference, especially in environments with reflective surfaces.

Constructed on an aerospace-grade PCB, the antenna offers robust durability against vibration and minor impacts common in FPV flight. The integrated 45-degree adapter allows for optimal positioning on goggle mounts, aligning the antenna’s wide 120-degree beam for maximum coverage during aggressive maneuvers and long-range excursions. Its broad bandwidth from 5.1 GHz to 6.7 GHz ensures compatibility with all common 5.8 GHz analog and digital FPV systems.

Key Features

  • Compact Mk. II Design: Measures only 32x32mm, offering a significantly reduced profile for streamlined goggle mounting.
  • High-Gain Directional Performance: Delivers 9.5–10.5 dBic gain for extended range and stronger signal penetration.
  • Wide Flight Beam: 120-degree beam-width provides a generous reception cone, reducing the need for precise head tracking.
  • Superior Axial Ratio: Engineered for excellent polarization purity, minimizing signal degradation from multipath reflections.
  • Integrated Angled Adapter: Built-in 45-degree connector facilitates an ergonomic fit on most FPV goggle antenna ports.
  • Broadband Compatibility: Covers the full 5.1–6.7 GHz spectrum, supporting all standard 5.8GHz FPV video transmitters.
  • Durable PCB Construction: Aerospace-grade printed circuit board ensures reliability and consistent electrical performance.

Applications

  • Long-range 5.8 GHz analog or digital HD FPV exploration builds.
  • Freestyle and racing drones where consistent video signal during complex maneuvers is critical.
  • Goggle-mounted diversity receiver setups, paired with an omnidirectional antenna.
  • Cinewhoop and micro long-range builds requiring a compact, high-gain directional antenna.
  • Fixed-wing FPV aircraft where a wide beam-width aids in maintaining link during banking turns.

Frequently Asked Questions

What is the advantage of the 45-degree integrated connector on this antenna?

The integrated 45-degree RP-SMA connector allows the antenna to sit at an optimal angle when mounted on FPV goggles, aligning its directional beam for better coverage during flight. This ergonomic design improves signal reception without requiring bulky external adapters and helps maintain a low profile on your headset.

Is this antenna compatible with both analog and digital HD 5.8 GHz systems like DJI FPV?

Yes, the TrueRC X-AIR Mk. II covers the full 5.1–6.7 GHz bandwidth, making it compatible with all common 5.8 GHz FPV systems. This includes analog video transmitters as well as digital HD systems such as DJI FPV, Walksnail, and HDZero. Its LHCP polarization matches the standard used by most high-performance VTX and VRX setups.

How does the wide 120-degree beam-width benefit FPV flying?

A 120-degree beam-width provides a broad reception cone, meaning you have a larger effective signal area. This reduces the need to constantly point your head (and goggles) directly at the drone, which is especially useful during freestyle maneuvers, racing around obstacles, or when flying long-range where precise head tracking is impractical.
