Definition
A continuous range of frequencies lying between two defined limits, used to group portions of the radio spectrum for a specific purpose such as voice communication, navigation, or broadcast.
Plain English
A stretch of radio frequencies that sit between a lower and an upper limit and are grouped together because they are used for the same kind of job.
Context Anchor
Seen in discussions of aircraft radios, navigation receivers, antennas, and other equipment that sends or receives radio signals.
Derivation
From Old English 'band,' meaning a strip or something that binds. In radio, the idea is the same — a strip of frequencies bound together between two limits.
Why Pilots Care
Knowing the correct band ensures the radio reaches the intended station and avoids interference from other services.
Analogy
Think of the whole radio-frequency range like a long road. A band is one marked section of that road reserved for a certain kind of traffic.
Intuition Check
Band does not mean a musical group or a strap here. In aviation radio use, it means a defined range of radio frequencies.
Example Sentence 1
Air traffic control voice communications take place in the VHF band between 118 and 137 MHz.
Example Sentence 2
The transponder transmits on the L-band frequency.
