DJI FPV best RANGE which Antennas on Goggles and Air Unit

While doing "wingsuit style" DIVES with my quad in the alps, the last thing I want are RED RSSI indicators making me nervous. I was quite sure that my AIR Unit antennas are not placed optimal, and I knew there was more potential on the goggles antennas as well. Since DJI logs Bitrate for you in a file, you can test antennas and compare the LOG data in excel.
After this test-sessions on the field I swapped the menace patch with an ORT 3turn helical - it has a flexy SMA cable and better performance as well.
Overall I'm pretty confident with this VIDEO TRANSMISSION now!

DIVES like in the old days - but with modern gear

Hi dear RCSchim blog reader,
been busy flying with the Sector 5 (HGLRC, Review here) with DJI FPV system installed, Crossfire for control link and this all topped with Gopro7 in 4k30 with hypersmooth. I can't believe how much the technology has evolved in the last years (see my first DIVES and these new ones in comparison to see what I mean).

6S Battery Comparison (Racing Drone Packs)

That's a long video, USE the Jumpmarks in my VIDEO INDEX below for easier access to what matters to you. Grab some popcorn and whatch the whole thing if you've got time :)

If you're curious about how to CONVERT DJI SRT files to be useable in Excel, find the script here on a google drive: https://bit.ly/2waB7vD
There's also the FULL XLS Sheet I used in this review, check out the data in detail there.
I've included a 2nd SRT converter script there to re-format those SRTs for the essential infos (VOLT + Latency + Bitrate). If you want to get a tutorial how to overlay the data in a video (as I have here) let me know. If there's enough interest in it I'll do a tut...
