More gain and more convenience! This is the adaptation of the all-mighty X²-AIR into a slick low profile face mount for the HDzero VRX4 module. Simply slide on the antennas on the module’s rails and screw on the custom knurled SMA connectors. Improved 13dBic gain and massive combined beam width of 165deg, yield an amazing flight experience in the toughest conditions. Fill the remaining ports with a pair of OCP and you got the antenna full house.

Dual elements array provide 13Dbi circular polarized beam of 75deg

By combining the two elements onto a single feed, the gain is boosted and horizontal coverage is widened by compromising the vertical coverage which isn’t used much in FPV.

Low profile design, only 15mm thick.

Most compact antennas of this gain level at only 15mm thickness, letting you leave them on at all the time without fear of breaking them. The included double-sided foam tape gives a solid bound to your goggles’s face plate and install in minutes.

Custom made SMA connectors, fit the HDzero in style.

As with all other components of X²-AIR antennas, the custom SMA connector is made to the highest standards to fit your HDzero module perfectly and make sure every bit of RF power is transferred from the X²-AIR. A knurled finish provide easy tightening and a quality look exclusive to TrueRC.

Pair them with our OCP omni antennas.
