Help with TV channels in Ireland

Hello.
I will be moving to Ireland from the UK soon.
In the UK I've had acccess to most channels that I needed through Freeview: BBC, ITV, Channel 4 and radio channels such as BBC Radio 5 Live, BBC Radio Live Sports Extra and Talksport.
The set up seems different in Ireland as when I plug in a coaxial cable through my smart tv I get no channels.
Does anyone know what I need to watch and listen to the channels above in Ireland? I might be interested in Sky as well for NFL and tennis, but the other ones are priority. I want a good feed so not something like BBC Iplayer as that's too far behind to be useful.
