Why each option

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.

Acommonly used to cover large areas

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.

Blow gain

Directional antennas inherently have high gain due to their focused beam, not low gain.

Cprovides the most focused and narrow beam-widthCorrect

Directional antennas are designed to concentrate their radiated power into a specific angular region, creating a highly focused and narrow beam-width for signal transmission and reception.

Dreceive signals equally from all directions

Receiving signals equally from all directions is a characteristic of an omnidirectional antenna, not a directional one.

Ehigh gainCorrect

By focusing RF energy in a specific direction, directional antennas achieve higher gain, meaning they can transmit and receive signals over longer distances or with greater signal strength in that targeted direction compared to omnidirectional antennas.
