ultra high frequency wikipedia - EAS
- From Simple English Wikipedia, the free encyclopedia Ultra High Frequency (UHF) is a electromagnetic radiation. Especially its frequency is between 300 MHz and 3 GHz (3,000 MHz). Because of short wavelength, UHF has strong directivity and it has small area.

High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters). Frequencies immediately below HF are denoted medium frequency (MF), while the next ban…
