Which frequency band is primarily used by FM radios?

FM radios primarily utilize the VHF (Very High Frequency) band for their broadcasts. This frequency range typically spans from 30 MHz to 300 MHz. Specifically, FM radio stations usually operate within the 88 MHz to 108 MHz sub-range of the VHF spectrum. The characteristics of VHF make it particularly suitable for FM transmission, as it allows for better sound quality and less susceptibility to interference compared to lower frequency bands.

In contrast, other frequency bands serve different purposes. UHF (Ultra High Frequency) is generally used for television broadcasts, mobile phones, and some digital communication systems. SHF (Super High Frequency) is used for radar, satellite communication, and microwave transmissions. HF (High Frequency) is used for long-range radio communication, often involving amateur radio and international broadcasts. Each of these bands is designed for specific applications, highlighting why VHF is distinctively appropriate for FM radio use.
