Name the two primary types of antennas.

• A. Omni and directional
• B. Dipole and Monopole
• C. Yagi and Patch
• D. Spiral and Helical

Answer: (A)

Antennas are categorized by their radiation pattern: they can be omnidirectional, radiating energy uniformly around the horizontal plane, or directional, concentrating energy in a specific direction to gain range and reduce interference. Omnidirectional antennas provide broad, all-around coverage, while directional antennas focus power toward a particular area for increased reach. The other terms refer to specific designs or elements rather than this broad pattern category—for example, dipole and monopole are basic radiating elements, while Yagi and patch are particular directional designs, and spiral and helical are specialized shapes. So the two primary types are omnidirectional and directional.
