Hi all, I've been looking around but the only thing I seem to find are people saying they are getting the same range with the MA2 controller and the Smart Controller. I certainly don't 
I use my MA2 to monitor sea mammals and we have an authorisation to fly long distance for that purpose only. I've pushed the MA2 to 5.5km with the original controller with no issues at all, no break in HD reception, perfect. I'm sitting on a hill at about 50m above sea level when flying it.
I tested today with my new SC, and it's terrible, or I should say it's pretty much like my original Mavic 2 Pro (Ocusync 1.0) was.
Curious to see if anyone else has experienced that or can think about what the issue could be? Thanks!

- With MA2 controller, signal icon becomes orange (loses 2 bars) at about 4km. I am not sure when it gets red/loses full reception, but it'a definitely above 5.5km in my scenario.
- With SC controller, signal icon becomes orange (loses 2 bars) at about 1.7km, video starts pixelating, signal gets red about 2.5km then by 3km it's pretty much unusable, communication is lost, RTH kicks in. I got the antennas facing down making a 90 degree angle with the controller.
