Review: TrueRC X-Air MKII Antennas Upgrade for 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.

Where to Buy?

USD$59.99 for a set of two antennas, that’s all you need. Note that the two antennas are mirrored, not identical.

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. Truerc X Air 5.8ghz Mkii Directional Patch Antenna Dji Goggles 2 Fpv Mmcx 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 FPV Goggles. 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.

Get yours now before they are out of stock :) GetFPV: https://oscarliang.com/product-h1mp

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.

Based on the information I’ve just received, Goggles 2 (as well as Integra) purportedly employ linear polarization. Consequently, these antennas will not operate at their optimal capacity on these Goggles… Am I correct? Kindly confirm. Thank you!

Thank you for yet another perfect article, you’re the best!
I’m in the process of transitioning to those antennas, but I have the Integra, so the process takes a bit longer because I have to order parts from three different sides of the world :D
With stock antennas, my range on the Chimera7 Pro V2 was 4.6 km… I hope with these antennas it will be at least 7 km (in the Alps).
Anyway, without further ado, I’m only interested in one thing – I can’t find any data on how much gain the Integra antenna has. Thanks in advance for your response!

Are the antannas installed on the avata, linear? so using circular patch antennas with
linear antennas is not the optimal setup? You loose about 3dBm?

Reply
Oscar 5th February 2024 - 4:35 pm

Yes, it’s linear. And yes, mixing linear and circular will lose about 3db but the X-Air has way higher gain than the stock Goggles 2 antennas (way higher than 3db), so ultimately you will still gain range.

Could you point me in the right direction, I’m looking to improve my DJI googles 2 and dji avata, and if there’s anything else

How is it possible for DJI Air Unit to go so far? 13km limit was limitation of previous generation of DJI FPV Goggles? (V1&V2) and this does not account for Goggles2?

Your intelligence in this community is freakin awesome and you’ve helped me with your posts Many Times! Thank you for that…. Can you please tell me, with the Goggles 2 can you tell me what antenna I would need on my Cadxx Vista to make them work really well? I’ve connected them via new firmware, but range is horrid. I was told briefly the antennas are different. Can you please link me to the Vista antenna that will work flawless with the goggles 2? Thank you in advance.

Hi,

Isn’t the goggles 2 dual band 2.4 & 5.8? yet these antennas are only 5.8? would you be able to use these on an Avata or with remote controller 2?

Thanks

Reply
Oscar 28th April 2023 - 12:38 pm

2.4ghz is only used with their radio remote, so don’t use these antenna with the Avata.

in this case it will be ok to use TrueRC Duality 2.4/5.8 Stubby

Hey Oscar!
First of all – great respect that you share your knowledge in such a skilful and understandable way. Everyone from novices to professionals get a handful of information from your blog. On behalf of the FPV community – thx for this.
And secondly – you write that you are going to test them (TrueRc antennas) soon. I wonder if that has already happened? Because watching a few tests on YT I have the impression (after the comments after the videos I conclude that I am not the only one) that these antennas do not change much and the original ones are comparable [Googles 2 & O3]. Even considering the distance. Also, I’m curious about your opinion, have you already tested it yourself? Regards

HI ! i did a 15 km test with them with good success, had 15-17 mbps left at 15 km, will to 18 km next time.

have OSD proof of all this.

Question, If you are using the O3 air unit…. wichi is says is “dual-polarized”….. does it menas i need to choe 1 LHCP and 1 RHCP? or with 2 LHCP its done?

Reply
Oscar 14th April 2023 - 8:08 pm

I have seen tests done on the O3 Air Unit antennas, and the original antenna perform just as well as using 1 LHCP and 1 RHCP antennas, if not slightly better.
I hope to test this myself at some point, but from what we have seen the original antenna works just find and doesn’t need replacing (at least for now).
The test TrueRC did where they achieved 23Km was also using the original antenna on the O3 AU.

Reply
ray 4th June 2023 - 3:46 pm

NO. the O3 antenna has 2 linear mounted at 90 degrees to eachother within.

If I leave one stock antenna on, do I get both onmi and directional or it just wouldn’t work that way for reasons?

Reply
Oscar 29th March 2023 - 1:01 am

Yea you can do that if you want :)

BOB 6th April 2023 - 12:20 am

Lumenier sells adapters for goggles 2, so I might try two of their dual AXII antennas on it. They are like a flat-pancaked-ish omnidirectional, but at least they work front and back, I just have to tilt one up and the other one down, and they are long too so I don’t feel too bad bending them for portability.

Greg 7th March 2023 - 10:51 pm

Hey Oscar, I am just wondering, how did you confirm that the original DJI antennas were omni directional? Did DJI release that info?

Only asking because I heard they were directional. If they are omni, that would be much better for me, because I would have 2 different antenna configurations to choose from.

Thanks in advance!

Do these help with both transmission and reception? I use an ELRS radio with my O3 quads, so I think I only need to boost reception of the video signal. But I’m unsure what these antennas do exactly.

Reply
Oscar 7th March 2023 - 10:24 pm

Yes they boost transmission and reception range.

Rick 22nd February 2023 - 2:39 am

Be careful you don’t loose your antennas, they come out easily and it’s hard to get replacements at the moment.
