What frequency range does the VHF low band cover?

The frequency range that the VHF low band covers is indeed from 30 to 50 MHz. This segment of the radio spectrum is crucial for various communication purposes, including emergency services, public safety, and other forms of two-way radio communication. The VHF low band is particularly effective for long-range communication as it can penetrate through obstacles and has a longer wavelength, which helps in achieving wider propagation patterns, especially in rural areas.

The other frequency ranges mentioned in the alternative options correspond to different bands used for specific applications. The 150-174 MHz range is designated as the VHF high band, which is commonly utilized for public safety communications, while 450-512 MHz represents the UHF band used for various communication needs including law enforcement and commercial use. The 769-806 MHz range falls into the T-band, which is primarily used for specialized public safety purposes. Understanding these distinctions is essential for selecting the appropriate frequency band for various communications in emergency and professional settings.
