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.

Ultra High Frequency (band)

Ultra High Frequency was a Long Island, New York based alternative rock band.

History

Formed in 2001 by Frank Fussa (vocals / guitar), Jonny Brown (guitar / vocals), Chris Johanidesz (bass / vocals) and Dennis Joseph (drums / vocals), the band would go on to produce two LPs, two EPs and a number of singles.

In 2005 the band signed with White Elephant Recordings and their next full length Matter in Time (2006) was recorded at Laundry Room Studios in Seattle, Washington by producer/engineer Barrett Jones, known for his prior work with Nirvana and Foo Fighters. Upon its release the band toured the US, including notable dates with fellow Long Island bands Brand New and As Tall As Lions and would play one of the last shows at famed NYC club CBGB.

In 2007 the band relocated to Los Angeles to write for a new record and shift their focus to touring on the West Coast. While in California the band released the single 44 Mph, a slowed down version of their 2006 single 88 Mph and recorded a set of demos. After a Halloween show at the Viper Room the band announced it was their last show and they were breaking up. Frank and Chris have emerged with a new band called Morning Fuzz.

High frequency

High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 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 metres). Frequencies immediately below HF are denoted medium frequency (MF), while the next band of higher frequencies is known as the very high frequency (VHF) band. The HF band is a major part of the shortwave band of frequencies, so communication at these frequencies is often called shortwave radio. Because radio waves in this band can be reflected back to Earth by the ionosphere layer in the atmosphere – a method known as "skip" or "skywave" propagation – these frequencies are suitable for long-distance communication across intercontinental distances. The band is used by international shortwave broadcasting stations (2.310 - 25.820 MHz), aviation communication, government time stations, weather stations, amateur radio and citizens band services, among other uses.
