Where should the radial wires of a ground-mounted vertical antenna system be placed?
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?
How does the feed point impedance of a 1/2 wave dipole change as the feed point is moved from the center toward the ends?
Which of the following is an advantage of using a horizontally polarized as compared to a vertically polarized HF antenna?
What is the approximate length for a 1/2 wave dipole antenna cut for 14.250 MHz?
