DXer2,

I never personally saw the location when the station/transmitter was there but I am informed it is in the area of this link:

down to the left where a blue bin and telephone pole are visible.

BTW
It is interesting to note that the mediumwave "Tee" aerial for the other main pirate in the area up to 1989 (wlr) on 1197kHZ was still standing and looking intact for many years post 1988, until around the early 2000s ??? located on the north-western outskirts of waterford city near FM tower.

BTW Broadcaster Timmy Mallett was cycling around that area of Ireland in recent days and enjoying his Irish touring by bike!
