Noun
/juˌeɪtʃˈɛf bænd/
The UHF band refers to a range of electromagnetic frequencies in the radio spectrum that are typically used for television broadcasting, mobile phones, and other forms of wireless communication. UHF stands for "Ultra High Frequency," which generally ranges from 300 MHz (megahertz) to 3 GHz (gigahertz). The usage of UHF frequencies is prevalent in both oral and written contexts, particularly in discussions about telecommunications, broadcasting, and technology.
The term "UHF band" is relatively technical and is more frequently found in written contexts, such as technical manuals, academic papers, and industry literature. However, it can also be heard in conversations relating to telecommunications or media.
"The UHF band is essential for the transmission of high-definition television signals."
"La banda UHF es esencial para la transmisión de señales de televisión de alta definición."
"Many walkie-talkies operate on the UHF band to ensure clear communication."
"Muchos walkie-talkies operan en la banda UHF para asegurar una comunicación clara."
"Regulations for the UHF band have evolved to accommodate new wireless technologies."
"Las regulaciones para la banda UHF han evolucionado para acomodar nuevas tecnologías inalámbricas."
The term "UHF band" is not commonly used in idiomatic expressions, as it is more technical. However, various phrases can be constructed around the context of radio frequency and communication:
Meaning: Not able to communicate due to distance or interference.
"Signal lost on the UHF band."
"Señal perdida en la banda UHF."
Meaning: Communication has been interrupted or cannot be received.
"Clear signal in the UHF band."
"Señal clara en la banda UHF."
The term "UHF" is an abbreviation for "Ultra High Frequency," which has its origins in the 20th century as technology progressed and the need for higher frequency bands in telecommunications emerged.
