Radio electromagnetic spectrum refers to the range of frequencies of electromagnetic radiation that can be used for radio communication. The spectrum is divided into several bands, each with different characteristics and uses. Some examples of bands in the radio electromagnetic spectrum include: Very Low Frequency (VLF): 3-30 kHz, used for communication with submarines Low Frequency …

What does UHF stand for?

UHF in radio communications ¬†stands for ‘Ultra High Frequency’ The UHF frequency band covers the range between 300 – 3000 Mhz (Mega Hertz). UHF in radio communications is particularly useful in built up area such as cities, as the ‘wavelength’ is shorter the higher up ¬†in frequency you go. This means that the shorter wavelength …
