Description

The TrueRC X-AIR 5.8 Mk. II represents a refined generation of directional patch antennas, engineered for pilots prioritizing signal integrity over extreme distances. Its design utilizes advanced computer-aided engineering and high-quality PCB materials to achieve a wide 120-degree beamwidth and a high axial ratio, which translates to cleaner video feeds with reduced multipath distortion.

This antenna is optimized for the 5.1–6.7 GHz frequency spectrum, covering all standard 5.8GHz FPV channels used in both analog and digital HD systems like DJI, Walksnail, and HDZero. The compact form factor, a quarter the size of many traditional patches, allows for convenient mounting directly on FPV goggles without compromising on the generous coverage area, making it an ideal choice for long-range cruising, mountain surfing, and organized FPV racing events.

Key Features

  • Enhanced Beam Pattern: Features a -3dB beamwidth of 68 degrees within the total 120-degree coverage, concentrating gain effectively for a strong, stable signal.
  • High Axial Ratio: Maintains superior signal purity by effectively rejecting opposite-hand circular polarization, crucial for reducing video breakup in cluttered RF environments.
  • Broad Frequency Bandwidth: Covers 5.1–6.7 GHz, ensuring full compatibility with all 5.8GHz FPV video transmitters and future protocol developments.
  • Robust SMA Interface: Utilizes a standard SMA male connector for a secure, low-loss connection to receivers or adapter cables.
  • Goggle-Friendly Mounting: The lightweight 10g design and compact 32mm square footprint allow for secure attachment to most FPV goggle faceplates or tripod mounts.
  • Low Voltage Operation: Operates within a 2.7–5.5V range, making it directly compatible with the power supplied by most FPV video receivers and goggles.

Applications

  • Long-Range FPV Exploration: Ideal for fixed-wing planes, long-range quadcopters, and mountain surfing builds where maintaining a stable video link at distance is critical.
  • FPV Racing & Freestyle: Provides a wide, consistent signal window for pilots flying in environments with potential signal obstructions, reducing video dropouts.
  • Ground Station Receiver Arrays: Can be used in a diversity setup with an omni antenna on a ground station to automatically select the strongest signal source.
  • Digital HD FPV Systems: Compatible with DJI Goggles, Walksnail VRX, and HDZero receivers for enhanced digital video reception range and clarity.

Frequently Asked Questions

Is this antenna compatible with DJI FPV Goggles?

Yes, the TrueRC X-AIR Mk. II is compatible with DJI FPV Goggles (V1, V2, Goggles 2, Integra) when used with an SMA adapter or a module that has an SMA female port. Its LHCP polarization matches the standard used by DJI's air units and many other 5.8GHz video transmitters for optimal signal reception and reduced multipath interference.

What is the advantage of the 120-degree beamwidth?

A 120-degree beamwidth provides a very wide reception window, meaning you have a larger 'sweet spot' where the signal is strong. This reduces the need to constantly re-position your head or ground station antenna to maintain a clear video feed, which is especially beneficial during dynamic freestyle flying or when tracking a fast-moving racing drone.

Can I mount this antenna directly to my FPV goggles?

Yes, the antenna is designed for goggle mounting. Its compact 32x32mm size and lightweight 10g construction make it easy to attach securely to the faceplate of most FPV goggles using adhesive patches or a dedicated mount. Ensure your goggles have an SMA female port or you have the correct adapter (e.g., RP-SMA to SMA) for a proper connection.
