What are the standard frequency ranges for VHF communications?

The standard frequency range for VHF (Very High Frequency) communications is indeed from 30 MHz to 300 MHz. This band is commonly utilized for various forms of communication such as FM radio broadcasting, television transmissions, and two-way radio communications in aviation and marine applications.

VHF signals are particularly known for their ability to travel long distances over the horizon, especially when reflecting off the ionosphere, making them suitable for communication over significant distances without the need for line-of-sight. The characteristics of VHF frequencies allow for reliable communication in many situations, including during the day and at night, with a reduced impact from atmospheric noise compared to lower frequency bands.

The other frequency ranges listed in the choices correspond to different bands that serve distinct communication needs. For example, frequencies from 3 MHz to 30 MHz fall under the HF (High Frequency) range, which is primarily used for long-distance communication via skywave propagation. The range of 300 MHz to 3 GHz is classified as UHF (Ultra High Frequency), used for television broadcasts, mobile phones, and other communications, while the range of 3 GHz to 30 GHz is classified as SHF (Super High Frequency), typically used for microwave communications and satellite transmissions.
