Before they were decommissioned between 1982 and 1985, there were many instances of 405-line transmitters in the United Kingdom, having first been used in 1936. Below is a list of all transmitters:
Alexandra Palace in London hosted the first 405-line transmitter, active between 1936 and 1939, then again from 1946 through to 1956. From 1949 onwards the Band I VHF 405-line BBC transmitter network grew quickly.
| Channel | Vision Carrier Frequency |
|---|---|
| B1 | 45.00 MHz |
| B2 | 51.75 MHz |
| B3 | 56.75 MHz |
| B4 | 61.75 MHz |
| B5 | 66.75 MHz |
In 1955 with the advent of ITV a parallel effort to provide a Band III network was also underway. The pre-1955 BBC stations used the five channels of Band I, but with the introduction of Band III some BBC stations started appearing there too (most of them on channels 12 or 13). All ITV transmitters were in Band III (most on channels 8, 9 or 10).
| Channel | Vision Carrier Frequency |
|---|---|
| B6 | 179.75 MHz |
| B7 | 184.75 MHz |
| B8 | 189.75 MHz |
| B9 | 194.75 MHz |
| B10 | 199.75 MHz |
| B11 | 204.75 MHz |
| B12 | 209.75 MHz |
| B13 | 214.75 MHz |
There were eventually 41 high power "main stations" owned by either the BBC or the IBA (see below). Most were built during the 1950s. The BBC's last main station to enter service was Belmont in Lincolnshire in November 1966, the IBA's last main station was the Welsh service from St. Hilary which went on-air in February 1965.
The main stations were supported by a large number of off-air relay stations to fill awkward gaps in the service from the main stations. The last of these (Llanelli in south Wales (BBC) and Newhaven in southeast England (IBA) had been built by late 1970.
The entire system was decommissioned between 1982 and January 1985.
