Question A-007-007-001

For a 3-element Yagi antenna with horizontally mounted elements, how does the main lobe takeoff angle vary with height above flat ground?

Correct Answer

It decreases with increasing height

Explanation

As a horizontal antenna (like a Yagi) is raised higher above ground, the angle of the main radiation lobe (takeoff angle) generally decreases, which is favorable for longer distance DX communication via ionospheric reflection.
