Review: TrueRC X-Air MKII Antennas Upgrade for DJI Goggles 2

DJI Goggles 2

Finally, the long awaited antenna upgrade for your DJI Goggles 2 has landed – TrueRC X-Air MKII with MCX connector. I bought their antennas for the DJI FPV Goggles V1/V2 and they have been working exceptionally well (much better range than the original antennas), so I have high hope for these new antennas for the G2 as well.

 

Closer Look at the TrueRC X-Air MKII Antennas

The DJI Goggles 2 have two foldable antennas on top, they use MCX connectors and are easily removable.

 

The new TrueRC X-Air antennas are designed specifically for the DJI Goggles 2, and they also have MCX connectors.

They are a direct fit for the DJI Goggles 2 in place of the stock antennas. Simply pull out the stock antennas and push the X-Air in.

 

There are two more linearly polarized antennas inside the goggles (also omnidirectional). But to replace those you’d have to disassemble the goggles which isn’t something most people are willing to do. So we probably would have to leave those two internal antennas untouched, and just swap out the two antennas on the outside, which still shows massive boost in range.

Specifications

The TrueRC X-Air 5.8GHz MKII antennas appear to be identical to the previous patch antennas they released for the DJI FPV Goggles V1/V2, Walksnail Avatar Goggles and HDZero Goggles/VRX. This time it seems they just changed out the connector to MCX so they are compatible with the DJI Goggles 2.

The X-Air is a circular polarized patch antenna, you can choose between LHCP or RHCP. If you are going to use it with a Vista (which comes with LHCP antenna), then you should definitely want to choose LHCP.

Each antenna weighs at exactly 10.0g, double of the original antenna’s 5.0g, it’s still pretty light.

Specs from the manufacturer:

  • Bandwidth: 5.1GHz-6.7GHz
  • Gain: 9.5-10.5 dBic
  • Polarization: RHCP or LHCP
  • Beam-width*: 120deg
  • Beam-width @-3dB**: 68deg.
  • Connector: MCX male
  • Dimension: 34 x 34 x 24mm
  • Weight: 10.0g per antenna

*Coverage where reception is at least equivalent to an omni.
**Coverage where at least 70% of the max range is obtained.

Range Improvement

I am looking to testing them shortly, but according to a comment by TrueRC on Facebook, they have successfully tested at up to 30km range with the original DJI FPV Air Unit (not the O3) using these antennas. They also tested with the O3 Air Unit and got 23Km. That’s mind blowing if that’s true.

Downsides

These antennas are not foldable, and certainly not as compact as the original DJI antennas. You can remove them from the goggles pretty easily though. A quick google reveals that the MCX connectors have a minimum 500 mating cycles lifespan, so it shouldn’t be a huge issue.

The X-Air patches are directional antennas, they replace the original DJI antennas which are omnidirectional. As a result, you will gain more range directly in front of you, but lose range on your sides and behind you. When using these antennas, you have to be aware of where the quad is and possibly turn your head more often for optimal performance. They are certainly great for long range and penetration, but if you are just flying close to yourself in line of sight, there’s no need to upgrade to be honest.
