__________ antennas project a signal in only one direction and are most often used on the inside of an exterior wall pointing to the inside of the building for security reasons.

Question

BlackTom AI · Accepted Answer

When evaluating antenna types for projecting a signal in a single direction, the concept that fits this description is a directional antenna, which concentrates energy in a specific path rather than radiating uniformly in all directions.
Option 1: Directional. This choice directly matches the idea of antennas that project a signal in only one direction, commonly used to focus transmission toward a target area such as the inside of a building for security with centralized coverage.
Option 2: Microware. This appears to be a misspelling of Microwave and does not describe a directional property of an antenna type; microwaves refer to a frequency range, not a directional radiation pattern in itself.
Option 3: Omnidirectional. Antennas of this type radiate or receive signals equally well in all horizontal directions, which is the opposite of projecting in a single direction, so it does not fit the prompt.
Option 4: Radio. While radio antennas can be directional or omnidirectional, the term 'Radio' alone is too generic and does not specify a one-direction projection characteristic required by the description.
Option 5: Vertical. A vertical antenna describes orientation (upright) rather than the radiation pattern; vertical is not inherently about beam directionality toward a single area, so it does not meet the stated requirement.
In summary, options that imply multi-directional radiation or broad frequency concepts do not align with the description of projecting a signal in only one direction, whereas Directional explicitly captures the targeted, single-beam behavior intended for security-focused interior coverage.
