12.4.4 Adjusting the Antenna Tilt Angle
In order to make an accurate interpretation of a storm cell, the radar beam
should be pointed at the wet part of the weather cell to record the proper rainfall
intensity (color level). The ideal aiming point is just below the freezing level of
the storm. The best way to find this point is to use the Vertical Scan feature. The
antenna tilt angle can be centered on the strongest return area in the vertical
scan to get a more accurate view of the coverage and intensity of the target in
the horizontal scan.
1. While viewing the WX Radar page touch the
TILT
key. An
