Ultra high frequency

Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimetre band as the wavelengths range from one meter to one decimetre. Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is high enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications.

The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz. Two other IEEE radar bands overlap the ITU UHF band: the L band between 1 and 2 GHz and the S band between 2 and 4 GHz.

UHF (song)

"UHF" is an original song by "Weird Al" Yankovic in the key of E major and based on several different riffs. It is the theme song from the film UHF. It is a style parody of themes that are played to advertise television stations. The video parodies other artists and music videos popular during the 1980s, including Guns N' Roses, George Michael, Robert Palmer, Prince, Talking Heads, Peter Gabriel, ZZ Top, Billy Idol, The Beatles, INXS and Randy Newman.

UHF (Portuguese band)

UHF is a Portuguese rock band formed in the late 1970s in Almada by António Manuel Ribeiro (vocals, guitar and keyboard), Renato Gomes (guitar), Carlos Peres (bass) and Zé Carvalho (drums).

They were the driving force behind the Portuguese rock boom of the early 1980s. At this time very few rock bands had success singing in Portuguese.

UHF already had released their first single, "Jorge morreu" ("George died"), about a death by Overdose, when Rui Veloso, considered by many people as "the father of Portuguese rock", released his monumental first album Ar de rock ("Looks like Rock", a pun on "Hard rock", which is how it sounds in Portuguese). After Veloso's success, a second single, "Cavalos de corrida" ("Racing horses"), was released, followed by three very successful albums in Portugal: À flor da pele, Estou de passagem, and Persona non grata. The group has celebrated 35 years of existence in 2014, with the only member from the original formation being António Manuel Ribeiro, the leader and frontman of the band, and considered to be one of the best rock poets in the history of Portuguese Rock.

Very high frequency

Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 MHz to 300 MHz, with corresponding wavelengths of ten to one meters. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF).

Common uses for VHF are FM radio broadcasting, television broadcasting, two way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of kilometres with radio modems, amateur radio, and marine communications. Air traffic control communications and air navigation systems (e.g. VOR, DME & ILS) work at distances of 100 kilometres or more to aircraft at cruising altitude.

VHF was used for analog television stations in the US, and continues to be used for digital television.

Propagation characteristics

VHF propagation characteristics are suited for short-distance terrestrial communication, with a range generally somewhat farther than line-of-sight from the transmitter (see formula below).
