Band I

The VHF Band I ( in short: Volume I ) is the frequency range in the VHF range 47-68 MHz. This area demonstrate the television channels 2, 3 and 4, which are used in the terrestrial television and cable television. In cable networks, this frequency range is used depending on the upgrade status for the rear channels of Internet and telephony.

In the Radio Regulations Radio Regulations of the International Telecommunication Union, the band I in addition to other radio services is even allocated to the broadcasting service, but according to the frequency allocation plans of Germany and Austria should this tape be used in future no longer for television broadcasting.

Due to high power and long range it was possible to supply large areas with few stations, however, this frequency range is prone to ranges of up to 2000 km.

In Germany last sent (until November 2008), only the ox-head transmitter (Channel 4) in this frequency range. The Band I transmitter Biedenkopf (Channel 2), Kreuzberg (Channel 3), Gruenten (Channel 2), Raichberg (Channel 4), Flensburg (Channel 4) and Göttelborner height ( channel 2) were 2006 and 2007 under conversion off to DVB -T.

The so-called ox-head antenna for channel 4 was widespread in the GDR for the ARD receiving from the same transmitter site and colloquially the antenna for the Western television. Because delivery West Germany and East Germany used the same CCIR channel grid is possible.

For all the stations used VHF band I, spare channels were provided in the UHF band V. As these, however, have a much shorter range, only a few of the spare channels were also used ( eg channel 55 in Steinkimmen or channel 53 in Calau ). Numerous spare channels have been used elsewhere, such as the initially planned for the station ox head channel 60 was used in Würzburg for RTL Television.

Analogue TV channels and frequencies

Outline of the analog television channels in the VHF band I according to CCIR standard ( frequency information in MHz):

Channel 1 was theoretically defined as a channel, but found virtually no application. Outside of the usual grid existed the offset channel 2A, which was used in Austria by ORF in St. Pölten (transmitter Jauerling ) to switch on the transmitter to DVB -T. The frequency offset of the channel 2A avoiding mutual interference with a frequency similar TV channels after OIRT norm in Hungary. Channel 2a is 1.5 MHz above the frequency of the channel 2
