BASIC ANTENNA TILT SETUP

The following discussion is a simple method for setting up the weather radar antenna tilt for most situations.

It is not to be considered an all encompassing setup that works in all situations, but this method does provide

good overall parameters for the monitoring of threats. Ultimately, it is desired to have the antenna tilted so that

the bottom of the radar beam is four degrees below parallel with the ground. The following example explains

one way of achieving this.

With the aircraft flying level, adjust the antenna tilt so ground returns are displayed at a distance that equals

the aircraft' s current altitude (AGL) divided by 1,000. For example, if the aircraft is at 14,000 feet, adjust the

tilt so the front edge of ground returns are displayed at 14 nautical miles. Note this antenna tilt angle setting.

Now, raise the antenna tilt 6 degrees above this setting. The bottom of the radar beam is now angled down 4º

from parallel with the ground.
