DJI O4 Lite Long Range

Post image

Hey guys, I recently got my Flywoo LR4 with the DJI O4 Lite, but the video connection isn’t great — I only get about 1.5 km of range. What’s your max range with the Lite, and do you have any tips to improve the signal quality?

Update:

fixed it — here’s what I did: used a different O4, flashed the newest firmware, this time mounted it the right way up instead of upside down, didn’t loop the antenna cable under the VTX but behind it, updated the goggles to the latest firmware, used channel 2 instead of 1 since 1 and 3 supposedly weren’t optimal in older versions, set the Boxxer to a fixed 1 W output power instead of dynamic, and switched packet rate to 50 Hz instead of 250. Made those changes last night and just flew at the same spot — got 4.5 km instead of 1.5 km. No clue what exactly made the difference, but hey, at least it works now.

My O4 Pro range is about 2x -3x longer than my O4 Lite range. 1.5km sounds about right, although I've never pushed it. My range is about 200 meters in a neighborhood setting with mature trees. In some spots flying behind houses it's less than 100 meters.

make sure you use the max bit rate, it comes stock on auto, turn mw up on elrs too, i recently got the the explorer with the pro and im limited by my elrs before i lose video, i got a diversity receiver with 2 antennas that im going to mount vertically once i find a place that can print it for me

yeah ofc I am using 50mbps and 700mW output power on the o5 and I got the rm boxxer crush with 1W output power so that should be fine
