False.

High Frequency (HF) radio waves are primarily used for long-distance communication, not short-range communication. HF radio waves have the ability to travel long distances because they can bounce off the Earth's ionosphere and follow the curvature of the Earth. This property makes HF communication suitable for purposes like long-range aviation, maritime communication, and long-distance radio broadcasting.

For short-range communication, especially within a limited area, other frequency bands like Very High Frequency (VHF) and Ultra High Frequency (UHF) are typically used because they provide more direct and line-of-sight communication and are less affected by atmospheric conditions.
