What kind of reception restrictions are VORs subject to?

VOR reception is governed by line-of-sight geometry and the height of the transmitting antenna. VOR signals travel mainly in a straight line and don’t bend much through the atmosphere, so you must have a clear path between the aircraft’s receiver and the VOR antenna. The distance over which you can reliably receive the signal—the service area—depends on how high the VOR antenna sits and how high the aircraft’s antenna is; higher elevations give a longer radio horizon and extend coverage. Weather or time of day don’t significantly affect VOR reception, and aircraft speed doesn’t change the basic reception geometry. So the key idea is that reception is limited by line-of-sight and the transmitter’s altitude.
