What type of radio operates on a low range frequency?

The correct answer is VHF Radio. VHF, or Very High Frequency, operates typically in the range of 30 MHz to 300 MHz. This frequency range is effective for communication over moderate distances, often utilized in marine, aviation, and emergency services communications, including emergency medical services. VHF radios provide clear communication in areas with line-of-sight paths and are less affected by physical obstructions compared to higher frequency radios.

UHF, or Ultra High Frequency radios, operate on frequencies from 300 MHz to 3 GHz. These radios are often used for shorter-range communication and perform better in urban environments due to their ability to penetrate buildings. HF (High Frequency) radios, which operate from 3 MHz to 30 MHz, are effective for long-distance communication, particularly over the horizon due to their ability to reflect off the ionosphere. Spectrum Radio is not a standard classification of radio frequency, thus it lacks a clear definition within the context of amateur or professional radio communication.

By understanding the specific ranges and applications of each type of radio frequency, one can determine the appropriate use for different communication needs in emergency and non-emergency scenarios.
