From 1985 and before Freeview it became a popular transmitter from which to receive Channel 4 which was not broadcast on Welsh transmitters (Channel 4 launched in 1982, but wasn't available from Huntshaw Cross until the summer of 1984). Evidence of this can easily be seen in Swansea (for instance) where many Group C/D TV aerials can be seen pointing south, across the water. The 405-line transmissions from Huntshaw Cross were discontinued in the 2nd quarter of 1983, somewhat before the final UK-wide shutdown of the VHF system in January 1985.
