Select two properties of a directional antenna.

Directional antennas focus their radiated power in a specific direction, leading to a more concentrated signal. This concentration results in a high gain, meaning the antenna is more efficient at transmitting and receiving signals along its intended path. The focused energy also creates a narrow beam-width, which is the angular measure of the antenna's coverage. This narrow beam is ideal for point-to-point links or covering specific areas, rather than broad coverage. Omnidirectional antennas, in contrast, receive signals equally from all directions and are typically used for covering large areas with lower gain.
