What is the HF frequency range?

The correct answer identifies the HF (High Frequency) range as 2-29.999 MHz. This range is crucial in military and civilian communication systems because HF frequencies are widely used for long-distance communication, especially over the horizon. This capability is largely due to the phenomena of skywave propagation, where signals can be reflected off the ionosphere, allowing them to travel much farther than they would on line-of-sight alone.

HF is highly favored for tactical radio communications in the field since it provides a reliable means of communication despite geographical obstacles, which can be critical in various operational environments. Understanding these frequency ranges is vital for any personnel working with communication equipment as it influences equipment selection, communication strategies, and the effectiveness of transmissions in various scenarios. This knowledge directly supports mission success and operational readiness.
