Not planning on using my Dji antenna as I would like to use my true Rc stubby, Q is can I plug it into any of the UFL ports on the unit or is there a specific one I should use.
Did notice one say Ant 1 or something but not sure if theat ois the one im looking for ??.
So I’ve got a stubby that I plan to use with my 03 at some point. Mine definitely has two connectors just like the one that came with the 03 unit.
I suspect the one you have is for a vista and may not be compatible
Yah it did come off my vista, I thought that one of the UFL connection is for ur visual and the other for controller But maybe I’m wrong hence why I can’t find any info about them …
Might have to stick the one that came with it on means finding a STL for a Nazgul antenna protector 
been at it most of the bloody day…
After a quick google search it seems that you can either buy a two in to one style antenna such as the stock DJI one or two separate antenna.
I suspect if you have two separate antenna you will need to ensure that they are the correct polarity for the goggles you are using.
Personally I bought this as it’s a direct replacement.
I just found this on AliExpress: ￡15.99 | FlyFishRC Dual-Band 5.8Ghz/2.4Ghz ipex/UFL 40mm/95mm/145mm LHCP Long-distance Antenna Compatible DJI O3 Air Unit
I can understand why you’d think that and it may be correct.
In theory having two antenna should be better than that on the vista.
Probably better that you get something that’s meant for the 03 to avoid any further problems and head scratching mate 
Yeh I hear you mate what I might do is try it with a single see what kind of signal strength I get … if it’s crap then just stick the original on at least I’ll know 
cheers mate
Ended up printing a new antenna mount so I can use the supplied one
Just found the below, very interesring, anyone ever tried it ???.
Good find. Seems like it answers your question.
I use DJI controller on my 03 so no good for me unless I change
