Right up there anyway, though perhaps only amongst a certain generation. And I say that conscious of Carrauntoohil's height and Brandon's pilgrimage. I think I made this comment to Simon last weekend as we were on its slopes and as it amused him, so it may amuse you to know of its fame. Before I ever picked up a geography book in national school and learned about mountains I was a fan of the tv. Its been a long running affair, if anything it has deepened over the years. Anyway, as a child in the mid to late 70s, we had the grand total of 2 channels on a black and white telly. And we and all of my age lived in the fear of that dreaded message that regularly flashed up on our screens..."we apologise, there is a problem with our transmitter at Mullaghanish...". So when I say most famous summit in the SW, I mean amongst the people of the SW. It was almost like a mantra, everyone knew of this summit, it was pointed out to every wide eyed kid as the family drove over the county bounds between Cork and Kerry, it was a marvel of engineering and technology to us all, almost up there with Kerry Airport and the Dursey Cable Car.
Anyway, some facts lifted from www.irish-tv.com...
Because of the mountainous nature of the area served, it has the highest amount of relays for an Irish transmitter. That site says this is a "dubious honour"...I have to concede I don't actually know what this means!
It transmitted RTE's first attempt at regional television, in the early 1970s, with the programme Munster Matters. This was produced in Dublin and transmitted after RTE shut down at night, when Mullaghanish was the only transmitter that stayed on. The experiment failed, and so RTE stopped regional programming for decades afterwards.
It was one of the 5 original Teilifis Eireann transmitters, opening in 1962. Linkback: https://mountainviews.ie/summit/199/comment/6675/
