G9B07
How does the feed point impedance of a horizontal 1/2 wave dipole antenna change as the antenna height is reduced to 1/10 wavelength above ground?
Pick an answer to check it.
Answer: B. It steadily decreases
As a horizontal dipole is lowered toward 1/10 wavelength above ground, the ground's effect makes its feed point impedance steadily decrease, well below the free-space value of about 72 ohms.
Tip: Lower dipole, lower impedance.
