Question

What are two characteristics of a directional antenna? (Choose two.)

Options

Acommonly used to cover large areas
Blow gain
Cprovides the most focused and narrow beam-width
Dreceive signals equally from all directions
Ehigh gain

Explanation

Directional antennas are characterized by their ability to focus RF energy into a narrow beam, which results in higher gain and a more concentrated signal.

Common mistakes.

A. Directional antennas are typically used for point-to-point links or specific area coverage, not for covering large, general areas that usually require omnidirectional antennas.
B. Directional antennas inherently have high gain due to their focused beam, not low gain.
D. Receiving signals equally from all directions is a characteristic of an omnidirectional antenna, not a directional one.

Concept tested. Directional antenna gain and beamwidth
