TrueRC X-Air 5.8 Crosshair Antenna MK II RHCP (RP-SMA)
by True RC

The TrueRC X-Air 5.8 Crosshair Antenna MK II RHCP (RP-SMA) is a compact, high-performance 5.8GHz FPV receiver antenna, designed for long-range and wide-beam coverage. Built with aerospace-grade PCB material and computer-aided engineering, this redesigned version is nearly 75% smaller than the original while maintaining exceptional beam width and high axial ratio.

With a 9.5-10.5 dBic gain and 120-degree coverage, the X-Air 5.8 MK II ensures strong, reliable signal reception for long-distance FPV flights. Its optimized RHCP polarization minimizes interference, providing a clear and stable video feed without the need for frequent antenna adjustments. The RP-SMA connector ensures compatibility with a variety of FPV systems, making it an ideal upgrade for drone racing, freestyle flying, and long-range FPV applications.
