What is the frequency range of VHF high band?

The frequency range of VHF high band is indeed from 150 to 174 MHz. In the context of radio communication, VHF stands for Very High Frequency, which is subdivided into several bands. The VHF high band specifically encompasses frequencies used for various forms of communication, including public safety, broadcasting, and two-way radio systems.

This particular range is critical as it is commonly utilized for emergency services, allowing for effective communication among responders during incidents. Frequencies within this range provide a balance of decent range and good propagation characteristics, which are advantageous for both urban and rural communication needs.

The other provided ranges do not fit into the VHF high band classification. For instance, the 30-50 MHz range falls under VHF low band, while the ranges of 450-512 MHz and 470-512 MHz are classified as UHF (Ultra High Frequency). Understanding these distinctions is essential for anyone working in emergency communications or related fields, as it informs decisions on equipment selection and frequency allocation in various operational contexts.
