Among the several threads on this forum and on DJI forum regarding the issue of
Goggles RE and
Mavic 2 combo having signal range issues, I have seen others mention the same as you and after their testing (as well as my own) I notice an increase in range when locking in to 2.4Ghz, however, the increase is negligable. Mine has been consistently cutting out at 1000ft. When I lock it into 2.4Ghz, I made it approx 1100ft but this wasnt on every occurance.
So, Id say its part of the overall issue, but there is still much more to it.
Ive eluded to this in other forum threads that Im noticing an extreme correlation regarding signal cutout at 1000ft having alot to do with RF Interference in that area. Let me explain a bit...
So, Ive had 3 good flight with my
Goggles RE, where I made it 2+ miles out and all w/o the slightest signal loss... On the other hand, Ive had 60+ flights, using the
Goggles RE, where I was SOLID out to 900ft, then 950, stuttering FPV, then 1000ft, complete cutout, Black/White screen...
THE ONLY DIFFERENCE BETWEEN MY SUCCESFUL FLIGHTS VS MY 1000FT AWAY CUTOUTS WAS THAT I WAS FLYING OVER LAKE MICH where theres NO RF INTERFERENCE! (I even verified this with an RF Spectrum Analyzer)
All the other locations, where I had 1000ft signal cutouts were in residential areas, or parks, with residences nearby, where there was wifi in the area HOWEVER, not enough to hurt the
Mavic 2 signal when the
Goggles RE are not connected
THATS MY MAIN SIGNIFIER THAT THERE IS A REAL ISSUE WITH THE
GOGGLES RE!
WHEN I HAVE SIGNAL LOSS ON
GOGGLES RE, I IMMEDIATELY DISCONNECT/PWR OFF
GOGGLES, AND WITHIN 3 SECS, THE
MAVIC 2 REGAINS A FULL & SOLID SIGNAL, IN EVERY INSTANCE, AND THEN LITERALLY FLIES FOR MILES.
THATS MY MAIN TEST.
IMO, the issue rests in firmware, where the
Goggles RE just freak out in the presence of even the slightest bit of RF Interference.
Alas, we'll never know until DJI decides to give a **** about their customers and our investments!!! A LONG SHOT, Im starting to see.
