. S4C was added in 1982. 405-line TV was finally discontinued in the UK in 1985, but it appears that Arfon's VHF transmitters were decommissioned a year early in 1984 and More recently, Police and Ambulance communications have been added, in addition to mobile (cellular) telephone antennas. In 1993, Classic FM began using the site for FM coverage of north west Wales in preference to Llanddona (the BBC's regional FM site), partly due to a dispute over BBC charges for sharing fees of its transmitter masts and antennas, but more because Arfon, in conjunction with Great Orme's Head (near Llandudno) gave Classic FM better coverage than the BBC sites.
