In the UK, Channel 4 started in 1982. It was rolled out nationally over a short timescale. The UHF channels had been assigned as part of thejoint BBC/ITV band planning process which gave 4 channels to each transmitter. The aim was to achieve full national coverage (99% of population?). Channel 5 was shoehorned in much later. A bit of a bodge job, with large areas not covered.
The 405 line services in Bands I and III (Low and High band VHF) were finally tuned off in 1985. These bands have not been used for TV since then. There are still a surprising number of antennas visible.
