The V band ("vee-band") of the electromagnetic spectrum ranges from 40 to 75 GHz.   The V band is not heavily used, except for millimeter wave radar research and other kinds of scientific research. It should not be confused with the 600–1000 MHz range of Band-V (band-five) of the UHF frequency range.
Band member Antony Brant came up with the band name "V" because V is the Roman numeral for five and there were five members in the band. V made their debut at the same time as McFly by supporting Busted 's arena tour in the spring of 2004.
