These TrueRC X2-Air antennas are designed to fit onto the rail mount of the new HDZero VRX. In addition, they\’re excellent patch antennas, with a high maximum gain and an unusually wide beam angle. In this video, I cover the reasons you might want to use these antennas. I also compare them to the built-in patches on the Sharkbyte receiver to see whether they are worth the increased cost and bulk.
