Band V
Encyclopedia
Band V is the name of a radio frequency
range within the ultra high frequency
part of the electromagnetic spectrum
. It is not to be confused with the V band
in the extremely high frequency
part of the spectrum.
Sources differ on the exact frequency range of UHF Band V. For example, the Broadcast engineer's reference book and the BBC
define the range as 614 to 854 MHz. The IPTV India Forum define the range as 582 to 806 MHz and the DVB Worldwide website refers to the range as 585 to 806 MHz. Band V is primarily used for analogue and digital (DVB-T
& ATSC
) television
broadcasting, as well as radio microphones and services intended for mobile devices such as DVB-H
.
The following table shows TV channel allocations in Band V in the UK.

United Kingdom
In the UK, Band V allocations for television are 8 MHz wide, traditionally consisting of 30 channels from UHF 39 to 68 inclusive. There is also a channel 69, but in the UK, this is allocated to radio microphones. Semi-wideband aerials of the group E type cover this entire band. However, aerials of types group B and group C/D will cover the lower and upper halves of Band V respectively with higher gain than a group E.The following table shows TV channel allocations in Band V in the UK.
