Horizontal Antenna Patterns

The 2D horizontal pattern is displayed with top view. The angle stretches from 0 to 360° and is oriented counter-clockwise.

The direction of 0° is describing the direction with maximum gain. But this is not mandatory. Also, other directions can be used. But as the direction of 0° is often visualized in radio planning tools, it helps the network planner if the main energy is also radiated in this direction.
