Extra exam question E9H01

WhyA Beverage antenna should be at least one wavelength long to achieve good performance at its design frequency. A Beverage antenna needs to be at least one wavelength long to achieve good directional performance at its design frequency, since its directivity comes specifically from the traveling wave built up along that substantial length of wire, answer D. It isn't limited to a quarter wavelength (that would be far too short for a Beverage to work as intended), doesn't need to be mounted more than a wavelength above ground (Beverage antennas are typically strung low, close to the ground), and isn't configured as a loop, that describes a different receiving antenna type.
