When constructing a Beverage antenna, which of the following factors should be included in the design to achieve good performance at the desired frequency?
Its overall length must not exceed 1/4 wavelength
It must be mounted more than 1 wavelength above ground
It should be configured as a four-sided loop
It should be at least one wavelength long✓Correct answer
Explanation
A Beverage is a traveling-wave antenna: the signal induced in a long wire close to the ground builds up progressively as the incoming wave from the favored direction travels along it. That build-up needs at least a wavelength of wire, and preferably several, with the wire mounted low rather than high.
