- As the name implies, the signal transmitted does not include " inherent " directional information, in contrast to other navigational aids such as low frequency radio range, VHF omnidirectional range ( VOR ) and TACAN . NDB signals follow the curvature of the Earth, so they can be received at much greater distances at lower altitudes, a major advantage over VOR . However, NDB signals are also affected more by atmospheric conditions, mountainous terrain, coastal refraction and electrical storms, particularly at long range.
