Sorry but I did not express myself correctly.My point is that I noticed that wx radar saturates (no attenuation) more easily on approach than on climb , even if you work with the tilt,gain,rane, etc.
e.g: On gnd you check the wx and after take off it keeps aprox the same.
Prior to descent you scan the area but at low altitudes , even working with tilt up &/or gain it saturates more easily.
