I've been searching and haven't found one yet but that could just mean I have a green belt in google-fu.  Had my video cut out completely on me yesterday when I was 3 miles out, it happened as soon as I turned around and I'm guessing it's because of the medium sized battery and short antenna combo.  If I can't find one I'll just go to dual antennas because there are tons of those in all kinds of lengths but I do like the single antenna a lot.

Were you using the RC2 by chance?

I was not, I was flying with the Radiomaster Zorro with ELRS.

Same question, the shortness of the antenna definitely seems to cause some range issues independently of the RC2 issue that I've not seen people having on the dual antenna quads with ELRS
