What is the take-off angle in antenna terminology?

The angle above the horizon at which the antenna radiates the largest amount of energy.

Take-off angle is the elevation angle above the horizon at which the main lobe of the antenna’s radiation pattern reaches its maximum, meaning where the antenna radiates the largest amount of energy. This is the direction in which most power is sent into space. The other ideas don’t fit: radiating below the horizon would be downward energy, the impedance minimum refers to the feed-point electrical property, and a mechanical tilt is about how the antenna is mounted, not where its main energy goes.

The angle below the horizon at which the antenna radiates the largest amount of energy.

The angle at the feed point where impedance is minimum.

The angle at which the antenna is physically tilted
