Dublin is the only city on the island where four League of Ireland clubs share a catchment, so the soccer argument here is genuinely local: Shamrock Rovers out in Tallaght, Bohemians at Dalymount, St Patrick's Athletic at Richmond Park and Shelbourne at Tolka Park. Over the top of all that sits Croke Park, where the Dublin footballers play their Leinster and All-Ireland games in front of crowds no club side gets near. The other half of the picture is the Premier League. Dublin has enormous Liverpool, Manchester United and Arsenal followings, which is exactly why so many households end up paying for two or three services at once and still miss games. If you are testing a service here, the sensible plan is to check one League of Ireland Friday night and one Premier League weekend, because they rarely sit on the same channel.
Dublin is several markets at once for anyone judging a connection. The older inner suburbs like Rathmines, Drumcondra and Phibsborough are dense with converted houses and apartments where landlords rarely permit a dish, while the newer estates out through Tallaght, Blanchardstown and Clondalkin were built with fibre in mind. Dún Laoghaire and the coastal southside sit between the two. If you are renting anywhere inside the canals, the no-installation part matters more than the price, because permission for anything fixed to the outside of a building is often simply not available. The useful test in a Dublin household is a weekday evening between seven and ten, when the whole city is streaming at once and the local exchange is under real load, rather than a quiet Sunday morning when everything looks fine.
