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

The TrueRC X-Air 5.8 Crosshair Antenna MK II RHCP is a cutting-edge redesign of the original X-Air 5.8, now featuring aerospace-grade PCB materials and advanced engineering for superior performance. With a compact form factor—nearly 1/4 the size of the original—this antenna maintains high gain (9.5-10.5 dBic) and wide beam coverage (120°), making it ideal for long-range FPV applications.

Designed for minimal aiming adjustments, the X-Air 5.8 MK II ensures strong signal reception, even at extreme distances. Its high axial ratio improves signal clarity, reducing interference for clearer video transmission. Whether for FPV drones, long-range video links, or ground station setups, this RHCP directional antenna delivers exceptional results. The SMA male connector allows compatibility with various FPV receivers and systems.
