What is the frequency range of the airband?

The frequency range of the airband is 108.0 to 137.0 MHz. This specific range is designated for aviation communications, which includes both navigation and voice communication systems used by pilots and air traffic control. The lower end of this range (108.0 MHz) is primarily occupied by very high frequency (VHF) navigation aids like VOR (VHF omnidirectional range), while the upper end (137.0 MHz) is used for air traffic control communications and other aviation-related operations.

Utilizing this specific range ensures that these critical communications can occur without interference from other radio services, maintaining safety and operational efficiency in aviation operations.
