The ideal aiming point is just below the freezing level ofthe storm. The best way to find this point is to use the Vertical Scan feature. Theantenna tilt angle can be centered on the strongest return area in the verticalscan to get a more accurate view of the coverage and intensity of the target inthe horizontal scan.
