Cairn Hill transmission site

Cairn Hill transmission site is a broadcast facility near Longford that transmits television and radio signals across the surrounding region. The installation uses different frequency bands to deliver programming to homes and communities across a wide area.

The transmission site opened in 1978 as one of the first UHF television stations built by Irish broadcaster RTÉ. The location was part of an effort to expand television coverage and reach more people across the country.

The facility enables households across the region to receive radio and television broadcasts that are part of daily life for local communities. It connects people to national programming and shapes how the wider area accesses information and entertainment.

The site sits on elevated ground northeast of Longford and is generally not open to visitors since it remains an active broadcast facility. Those passing through the area will spot the antenna from a distance rising above the surrounding landscape.

The transmission station sends signals that reach far beyond Ireland's borders into Northern Ireland. This means people on the other side of the border can receive broadcasts from this station, making it an unplanned cross-border communications link.
