The majority of people receive UTV on cable/MMDS or satellite, though it is not on the Sky EPG in the Republic. "Deflectors" - an Irish uphamisim for unauthorised terrestrial retransmitters (which were illegal until 1999 but legal from then until 2012) were a method of reception mainly in the South and West but are now almost all gone. Note though that most of the deflectors in the South would have retransmitted HTV/S4C rather than UTV/Channel 4, at least until ITV went free to air on satellite.
Did this happen during he 1970s? and 1980s?
