Turn off contour lines in footprint :
Disable red TX nulls markers in footprint:

Select location for footprint beamcenter by clicking in the map!
NOTE: The plotter is based on ITU-R B0.1213-1 antenna pattern
First contour from beamcenter = -0.5dB
Next contours every -1dB until -30dB.
Then -35dB and -40dB follows
Every -5dB is marked with thicker line
TX antenna nulls is marked with red lines
The old footprint plotter can be found at Jens T. Sætre
