Product Description

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

Maximize your video link performance with the TrueRC X-Air 5.8 Crosshair Antenna MK II, featuring a factory-installed 45-degree SMA connector. This specialized configuration is engineered specifically for FPV pilots who want a seamless, low-profile setup on their goggles without the signal loss or mechanical weakness of added adapters.

Building on the heritage of the original X-Air, the MK II offers a revolutionary reduction in size—fitting the power of a high-gain phased array into a compact 32mm footprint. With 9.5-10.5 dBic gain and a massive 120-degree beamwidth, this antenna provides the punch needed for long-range penetration while maintaining a forgiving reception window. You get the benefits of a directional antenna without the need for strict head tracking or precise aiming.

The integrated 45-degree SMA Male connector is rigidly mounted to the antenna, ensuring it sits at the ideal angle for FatShark, Skyzone, and other analog or digital receiving modules that use standard SMA. This "direct-fit" design minimizes connection points, reducing insertion loss and ensuring a robust, vibration-resistant link perfect for racing drones, freestyle quads, and fixed-wing aircraft.

Designed to serve a broad spectrum of users—from high school STEM programs and collegiate drone teams to sUAS defense contractors and military operators—the X-Air MK II delivers the reliability required for critical video feeds. Its wide bandwidth (5.1-6.7GHz) ensures compatibility with nearly all 5.8GHz video systems on the market today.

Key Features:

• Integrated 45° SMA Connector: Factory-installed connector eliminates the need for adapters, reducing weight and potential failure points.
