What type of aircraft uses an omnidirectional, vertically polarized antenna?

• A. Helicopter
• B. Single-engine propeller aircraft
• C. VOR
• D. Jet aircraft

Answer: (C)

An omnidirectional, vertically polarized antenna is commonly used for VHF Omni-Directional Range (VOR) systems, which are ground-based radio navigation systems for aircraft. The omnidirectional characteristic of the antenna allows it to receive signals from all directions, which is essential for pilots navigating in three-dimensional space. The vertically polarized design helps ensure that the signals transmitted from the VOR stations are optimally received by the aircraft's navigation systems. While helicopters, single-engine propeller aircraft, and jet aircraft may also utilize antennas for various communication and navigation functions, the specific reference to an omnidirectional, vertically polarized antenna aligns directly with the VOR system and its operational characteristics. This distinctive feature is primarily seen in the context of VOR, making it the best choice among the options provided.
