What type of polarization do VOR antennas use?

• A. Vertical
• B. Horizontal
• C. Circular
• D. Elliptical

Answer: (B)

VOR antennas utilize horizontal polarization. This choice is significant because horizontal polarization helps improve the propagation of VHF signals in aviation. In a VOR system, the signals transmitted from ground-based antennas are designed to be received effectively by the directional receiving equipment on an aircraft. The horizontal polarization allows the signals to travel efficiently over the terrain and minimizes interference from obstacles, such as buildings or other structures that might occur in the vertical plane. By using horizontal polarization, VOR systems ensure that the aircraft can maintain accurate navigation data as the signal is less affected by typical obstructions encountered at lower altitudes. In the context of aviation navigation, the effectiveness of a VOR signal in differing environmental conditions makes horizontal polarization the optimal choice, thereby supporting reliable and accurate navigation for pilots.
