For your last question, no the water reflection doesn’t influence at all the radar sensor. It’s just for the reflection rendering of antenna above water.
On side note, with SD3 have you set your last sensor.dat values activated to match the GWX original ones?
Wait, you have a MEP environment?...it has others values than GWX also!
So you have a mix of values from MEP, TKSS18 and GWX...you’ll have some editing work mate!
