When choosing an FPV antenna, you want something reliable, efficient, and easy to use. This is where TRUERC antennas shine. Two of their popular models, the TRUERC X-Air and the X2-Air, are often compared by FPV pilots. Both antennas are designed to improve the performance of your goggles video signal, but they have some differences that could influence your decision based on your needs.
The TRUERC antenna is known for its compact size and great range. It’s ideal for pilots looking for a balance between portability and performance. It provides a solid, reliable signal that helps reduce interference and gives you a better connection, even when flying long distances.Â
In this review, we’ll break down the key differences between the TRUERC X-Air and X2-Air antennas, helping you choose the right one for your drone setup. Whether you’re a beginner or an experienced FPV pilot, understanding how these antennas perform can make a big difference in your flying experience.

Close Look
Both the X air and X2 Air antennas feature aerospace grade PCB materials and the latest computer-aided engineering, with no compromise on beamwidth or gain and current dimensions!
Compared to the first generation, the X Air 5.8G MK II is almost a quarter the size of the original. The X air is a square design, while the X2 AIR is a rectangular design, and I think this is to put two X AIR together to form the X2 AIR antenna. The product name and polarization are printed on the back of both, and the connector in the middle uses 3d printing to protect the connector, refusing to expose the entire connector.
By the way, the bronze pattern printing is the latest batch, and the old batch is still white pattern printing. The new and old patterns do not affect the use of functions, and the delivery is random.
Beam Width & Vertical Range
X2 AIR MK II Antenna
The antenna has a horizontal beam width of 150 degrees and a vertical beam width of 62 degrees. At -3dB, the horizontal beam measures 74 degrees, while the vertical beam is 34 degrees.
By combining both elements into a single feed, the antenna increases gain and widens horizontal coverage, though it slightly reduces vertical coverage, which isn’t as important for FPV flying. With an improved 13dBic gain and a wide beam width of 150 degrees, it delivers an exceptional flight experience, even in challenging conditions.
X AIR MK II Antenna
The antenna operates within a bandwidth of 5.1GHz to 6.7GHz, with a horizontal and vertical beam width of 120 degrees. At -3dB, the beam width for both horizontal and vertical narrows to 68 degrees.
Compared to the X2 AIR antenna, the X Air naturally looks slightly inferior, but still shows excellent beamwidth in a directional antenna of the same size.
Which One Should You Choose?
If you’re looking for an antenna that is compact, lightweight, and offers solid performance in most conditions, the X-AIR is a great choice. It’s easy to install and provides excellent signal quality, especially in wide-open spaces. On the other hand, if you need more power and are flying in challenging environments, the X2-AIR is worth the extra size. It offers superior signal strength and is better suited for long-range flights or areas with more interference.
Who needs it:
If you like to stand in the middle of the courtyard (open space) and fly 360 degrees around the house, then these two as directional mid-gain antennas are not very suitable for you. Because the picture is clear and the signal is strong in the 180-degree field of view in front of your goggles, once your drone is flying behind you, the signal will weaken until it loses signal. If you want to constantly switch from flying 360 degrees around the house to flying only 180 degrees, then I recommend the TRUERC omnidirectional antenna product with this directional antenna, this is the best solution for you.
Conclusion
Both the TrueRC X-AIR and X2-AIR antennas are excellent choices for FPV pilots, but they cater to slightly different needs. The X-AIR is ideal for those who want a balanced, all-around antenna that’s easy to use, while the X2-AIR is designed for pilots who demand the best range and performance, even in tough conditions. By understanding your flying style and the environments you usually fly in, you can pick the antenna that will best enhance your FPV experience.
