DJI O3 Range - DJI stock Linear antennas on your copter vs TrueRC CP antennas

Been testing DJI O3 with stock antennas and better TrueRC Singularity antennas (next pic) to find out how the bitrate will be if flying a bit further out...

In the right chart you see that the bitrate stays really nice in the high 30-40mbit range, where it is more around 20mbit when I was using O3 stock (mixed with TrueRC Xair2 on the DJI goggles v2 - which is an polarization mismatch!).

SO - maybe pairing the DJI goggles2 stock antennas with their stock O3 airunit antennas on the copter will yield better results than my (left) scenario...

But I'm pretty sure that many pilots will have a mixed situation (since we also use Vistas and CP antennas because we don't buy 10 new O3 airunits ;) for alle the quads yet :)

O.R.T. Digieyes V2 - DJI FPV dualband Patch antennas

Eko from ORT sent me these antennas SPECIFICALLY created for the DJI FPV drone. Since the V2 goggles and the DJI FPV drone use Occusync3 and here two frequency bands (2.4GHz and 5.8GHz) you need to take care which antennas you use (if you want to move away from the stock stubbies). On V1 DJI we could just use any 5.8GHz antennas (from analog times). One reason to move to such directional aftermarket antennas would be the very limited poweroutput in CE mode. Skip to my conclusion to see the results of my 5 testflights - or get some popcorn and enjoy the show ;)

Profiles are loaded on program start (if you change something in these XML files, restart the program! They are sometimes "connected" or nested together. If the parent is missing you wont see a child profile! Profile "Labels" are only visible below a spectrum if in spectrum settings the option "accept profiles" is active! It's better to choose the profiles in "Config" of Spectrum rather than with the Ribbon button... BASIC RF spectrum knowledge:

• RBW (bandwidth - how accurate do I look at RF?) lower is better (more accurate) but slower sweep
• VBW (video filter - low (100khz) filters MUCH, FULL settings means highest detail!) higher is better (less smoothing) but you see more noise (set to low if you only wanna see powerfull signals clean)

Surprising results! DJI Goggles Antenna tested 2.3km away (stationary!)

1st Test up there: https://youtu.be/RQML-azG4bQ 

Last week I did a practical flying test with the same antennas: https://youtu.be/8TYY1-3Lo_c 

These are the DJI goggles V2 antennas: https://youtu.be/FsKhaigxpJs 

I also tested the ORT Digieyes (which are quite similar to the ChrystalHDs): https://youtu.be/PvSZYhobc24

VAS Cyclops V2 vs Helicals vs iFlight Chrystal (Hexplorer)

ad a very nice early spring evening (finally longer days!) and first a great longrange flight, then enough batteries to test some DJI antennas for you. See how the VAS CYCLOPS V2 perform against iFlight ChrystalHD and Henriks Deathray Helicals... If you don't like this "realworld" testing approach, skip it and wait for the next test (which will be the stationary 2.3km distance test again.
