How does the radiation pattern of a horizontally polarized antenna vary with increasing height above ground?
Pick an answer to check it.
Answer: B. The takeoff angle of the lowest elevation lobe decreases
Raising a horizontal antenna higher above ground lowers the takeoff angle of its lowest lobe. Lower angles favor long-distance contacts.
Tip: Higher antenna, lower takeoff angle.
