In the world of wireless communication, frequencies play a crucial role in determining how effectively signals are transmitted and received. Two commonly discussed frequency ranges are Ultra High Frequency (UHF) and High Frequency (HF) . In this blog post, we will explore the differences between UHF and HF frequencies, their applications, advantages, and how they impact communication systems. What Are UHF and HF Frequencies? High Frequency (HF) HF refers to frequencies in the range of 3 to 30 MHz . This band is primarily used for long-distance communication because it can reflect off the ionosphere, allowing signals to travel beyond the horizon. HF is widely utilized in amateur radio , aviation , maritime communication , and shortwave broadcasting . Ultra High Frequency (UHF) On the other hand, UHF refers to frequencies ranging from 300 MHz to 3 GHz . UHF is commonly used for television broadcasting, mobile phones, GPS, and two-way radios. Unlike HF, UHF signals travel in a straight ...
