Flying today to check range on my new antennas (fatshark antennas, immersion rc 600 transmitter mw)
600 m and i lost fpv connection on approx 100 m hight
If you have a channel scanner on your FPV, try getting 10 m or so away and scan for the best signal. Mine chooses 7 and I've gotten as far away as 1.1km with video on FPV still pretty good. I have the lilliput with stock antenna.
I forgot to mention that I also use the ImmersionRC 600 mw transmitter
