Ham Radio General Class Practice Test

Which description fits a Beverage antenna?

1. A vertical antenna constructed from beverage cans

2. A broad-band mobile antenna

3. A helical antenna for space reception

4. A very long and low directional receiving antenna

The correct answer is: A very long and low directional receiving antenna

A Beverage antenna is best described as a very long and low directional receiving antenna. This type of antenna is designed primarily for receiving low-frequency signals, particularly in the shortwave range, and is known for its effectiveness in maximizing the reception quality of weak signals. The design typically consists of a long wire that is laid out parallel to the ground, often at a height of only a few feet, which helps improve the reception of low-angle radio waves. This positioning takes advantage of the ground wave propagation characteristics associated with these frequencies. The directional nature of the Beverage antenna allows it to be oriented towards specific points of interest, enhancing the reception from those directions while minimizing interference from others. The other descriptions do not accurately represent the typical characteristics and purpose of the Beverage antenna. For example, beverage cans do not form a functional antenna, a broad-band mobile antenna implies a design for different frequencies rather than long wavelength reception, and a helical antenna is typically used for transmitting and receiving signals from space or for specific applications that require different design principles than those used in a Beverage antenna.
