UHF, conventionally defined portion of the electromagnetic spectrum, encompassing radiations having a wavelength between 0.1 and 1 m and a frequency between 3,000 and 300 megahertz. UHF signals are used extensively in televison broadcasting. UHF waves typically carry televison signals on channels.
Feb 22, 2018 · Ultra high-frequency (UHF) band: 300 MHz to 3 GHz (1 m to 10 cm) - this is also referred to as the decimeter−wave (dm−wave) band; Super high-frequency (SHF) band: 3 GHz to 30 GHz (1 cm to 1 cm) Extremely high-frequency (EHF) band: 30 GHz to 300 GHz (1 cm down to 1 mm) - this is also referred to as the millimeter−wave (mm−wave) band
UHF radios use a variety of frequencies, including: 450 MHz: This frequency is often used for commercial radio services, such as land mobile radio systems used by transportation companies. 470-512 MHz: This frequency range is used for public safety radio services, such as police and fire department communications.
Jul 21, 2023 · UHF represents a higher frequency range than Very High Frequency (VHF) and falls between the frequencies of 300 MHz (Megahertz) and 3 GHz (Gigahertz). UHF signals are widely used for various applications, including television broadcasting, mobile communication, satellite communication, wireless data transmission, and more.
Jul 14, 2015 · Ultra high frequency (UHF) refers to the band of electromagnetic radiation with a radio frequency range between 300 MHz and 3 GHz (3000 MHz). This band is also known as the decimeter band, with a wavelength ranging from 1 m to 1 dm.
Measurement. Mechanical oscillations. See also. References. External links. Radio frequency ( RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency [1] range from around 20 kHz to around 300 GHz.
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. 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.
