Which statement about TACAN range is true?

Explanation:
TACAN range is determined by line-of-sight propagation. The system uses UHF radio waves that travel in straight lines, so signals are limited by the curvature of the Earth and the relative heights of the aircraft and the ground station. The higher you fly (and the higher the station is), the farther the horizon, and thus the farther the usable TACAN range. Weather can influence signal slightly, but it doesn’t create unlimited range. TACAN is a ground-based aid, not satellite-based, so its range isn’t determined by satellites.
