| has gloss | (noun) 300 to 3000 megahertz UHF, ultrahigh frequency |
| has gloss | eng: Ultra High Frequency (UHF) is a electromagnetic radiation. Especially its frequency is between 300 MHz and 3 GHz (3,000 MHz). Because of short wavelenth, UHF has strong directivity and it has small area. UHF is commonly used for television signals. It is strong enough to be protected from other signal, but because of its strong directivity, receiving error by an obstacle occurs more. Hence it needs sensitive sensors. Uses UHF frequencies have higher attenuation from atmospheric moisture and benefit less from bounce, or the reflection of signals off the ionosphere back to earth, when compared to VHF frequencies. The frequencies of 300–3000 MHz are always at least an order of magnitude above the MUF (Maximum Usable Frequency). The MUF for most of the earth is generally between 25–35 MHz. Higher frequencies also benefit less from ground mode transmission. |
| has gloss | eng: Ultra high frequency (UHF) designates a range of electromagnetic waves with frequencies between 300 MHz and 3 GHz (3,000 MHz), also known as the decimetre band or decimetre wave as the wavelengths range from one to ten decimetres (10 cm to 1 metre). Radio waves with frequencies above the UHF band fall into the SHF (super high frequency) and EHF (extremely high frequency) bands, all of which fall into the microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. See Electromagnetic spectrum and Radio spectrum for a full listing of frequency bands. |
