Refer to the exhibit. Which antenna emits this radiation pattern?
The correct answer is A. omnidirectional. The exhibit shows a radiation pattern characteristic of an omnidirectional antenna, which broadcasts signals in a 360-degree horizontal pattern.

Why each option
The exhibit shows a radiation pattern characteristic of an omnidirectional antenna, which broadcasts signals in a 360-degree horizontal pattern.
An omnidirectional antenna is designed to radiate radio frequency (RF) energy equally in all horizontal directions (360 degrees), producing a radiation pattern often described as a "donut" shape. This pattern is suitable for general coverage in an area.
RP-TNC (Reverse Polarity TNC) is a type of coaxial cable connector, not an antenna type or a radiation pattern.
A dish antenna is a highly directional antenna designed to focus RF energy into a narrow beam, making it unsuitable for broad, 360-degree coverage.
A Yagi antenna is a directional antenna that concentrates RF energy in a specific direction, differing significantly from an omnidirectional pattern.
