Multiple Choice

The preferred location of a VOR antenna on light aircraft is on.

VOR reception is best when the antenna has an unobstructed view of the sky and is high above the aircraft structure. Placing the VOR antenna on top of the cabin puts it above most of the airframe, keeping it away from shielding by wings and fuselage and reducing multipath reflections from the airframe. The two elements arranged in a V with the apex pointing forward ensures the antenna is oriented to present the proper directional pattern and preserve the correct phase relationship between the elements, which helps the navigation receiver determine the bearing accurately. Mounting it on the bottom, in the cockpit, or at the tail would place the antenna inside or behind metal where the signal is more easily weakened or distorted, leading to poorer reception.
