TrueRC X²-AIR 5.8 MK II RHCP RP-SMA Directional Patch Antenna

RHCP (Right-Hand Circular Polarization) is specifically designed to combat multipath interference, which is a common cause of video static and breakup in FPV flying. When signals bounce off objects like trees or buildings, RHCP antennas reject these reflected, out-of-phase signals more effectively than linear polarized antennas, resulting in a cleaner and more stable video feed, especially in complex environments.

Yes, the TrueRC X²-AIR 5.8 MK II is universally compatible with any 5.8GHz FPV system that uses an RP-SMA female connector, which is the industry standard for most video transmitters (VTXs), receivers (VRXs), and FPV goggles. Its broad 5.1–6.7 GHz bandwidth covers all standard analog channels and digital HD systems like DJI, Walksnail, and HDZero operating in the 5.8GHz band.

For optimal performance, the antenna should be mounted with its flat patch surface facing the direction of your drone. The wide 150° horizontal beamwidth provides good coverage, but signal strength is strongest directly in front of the antenna. It is ideal for mounting on a fixed-position ground station, tripod, or on a drone's frame where it can maintain a consistent orientation towards the pilot or home point.
