Product Description

TrueRC X-Air 5.8 Crosshair Antenna MK II (Factory 45° RP-SMA) - LHCP

Optimize your signal integrity and digital reception with the TrueRC X-Air 5.8 Crosshair Antenna MK II (LHCP). Featuring Left Hand Circular Polarization and a factory-installed 45-degree RP-SMA connector, this antenna is precision-engineered for pilots running DJI Digital FPV systems (V1/V2 Goggles) or analog pilots looking to separate their video signal from the standard RHCP crowd.

The MK II represents the pinnacle of compact antenna design. By utilizing high-grade PCB materials, TrueRC has shrunk the high-gain Crosshair element down to a 32mm square without sacrificing performance. It delivers a robust 9.5-10.5 dBic gain and an expansive 120-degree beamwidth, ensuring you maintain a glitch-free video feed even when flying behind obstacles or at the edge of your range.

The integrated 45-degree RP-SMA connector is the standout feature of this model. Unlike setups requiring bulky adapters that can loosen or degrade signal, this antenna mounts directly to your goggles at the perfect reception angle. This streamlined design is critical for reducing insertion loss and maintaining a low profile for transport.

Ideal for high-density racing environments, commercial sUAS operations, and educational robotics teams, the LHCP polarization helps reject interference from other pilots flying standard RHCP gear. With ultra-wideband performance spanning 5.1GHz to 6.7GHz, this antenna is future-proof and ready for any 5.8GHz frequency requirements in both civilian and government applications.

Key Features:

• Native LHCP Polarization: Perfect for DJI Digital FPV Goggles (V1/V2) and high-interference racing environments.

• Integrated 45° RP-SMA Mount: Factory-fixed angle eliminates the need for adapters, improving durability and signal purity.

• Exceptional Gain-to-Size Ratio: Offers ~10dBic gain in a footprint barely larger than a standard patch antenna.

• Massive Bandwidth: Consistent performance from 5.1GHz to 6.7GHz ensures reliability across all available channels.
