Couldn't many viewers in the Republic receive BBC NI and Ulster TV when Telefís Éireann began in 1961 (with some viewers in Dublin and the south-east also being able to receive BBC Wales and TWW)?
It was Teledu Cymru from the Preseli transmitter that was receivable in SE Ireland, and that didn't start until Sept 1962, however, yes you're right, there were so many UK TV viewers in Eastern Ireland, obviously using 405 line sets, that RTE were forced to launch on 405 lines in those areas, (rather than exclusively on 625 lines)
remember Ireland had cable television way before the UK< starting in the late 1960s to bring the British channels to viewers in the Irish republic, starting off in Dublin.
