Our high-efficiency TrueRC X-AIR MK II transforms into a sleek, low-profile face mount for the HDzero VRX4 module. Slide the antennas onto the module’s rails and screw on the custom knurled SMA connectors. With a great 10dBic gain combined with a healthy flyable beam width of 120 degrees, it yields an amazing flight experience in a compact and low-profile package. Fill the remaining ports with a pair of OCP, and you have a full house of antennas.
