18. Which of the following antennas is designed to give a 360-degree coverage pattern in the horizontal plane?
- Directional
- Unidirectional
- Omnidirectional
- All of the above
Answer: C) Omnidirectional
Explanation:
In antenna theory, omnidirectional refers to the property of an antenna that transmits or receives electromagnetic waves equally in all directions. An omnidirectional antenna is designed to give 360-degree coverage and is commonly used in situations where a signal must be broadcast or received in many directions.
