Émetteur de Traînou, Broadcasting tower in Traînou, France

Émetteur de Traînou is a 200-metre guyed steel mast at the corner of the route de Fay-aux-Loges (D11) and the chemin d'Orléans à Sully-la-Chapelle, 2 km from Traînou. The lower and middle sections are painted white, the top in red and white bands; two platforms below the banded section carry white drum-shaped and vertical antennas, and a building at its foot houses the transmitters.

The Traînou transmitter broadcast five analogue television channels until 19 October 2010, and was the only transmitter of France 5 / Arte and M6 in the Loiret. On 5 April 2016 all TNT switched to MPEG-4, ending multiplexes R5 and R8 and adding LCI and France Info. On 11 June 2024 the R9 multiplex in HEVC was activated, and since 6 January 2025 the site carries the local station ICI Orléans, formerly France Bleu Orléans.

The site is run by TDF and carries four public FM stations, all at 3 kW, including the local station ICI Orléans, renamed from France Bleu Orléans on 6 January 2025 and covering Loiret and Loir-et-Cher. Drivers pass it at the corner of the route de Fay-aux-Loges (D11) and the chemin d'Orléans à Sully-la-Chapelle, 2 km from Traînou village.

The facility is located roughly 20 kilometers east of Orleans and is visible from nearby roads. As an active transmission station, the site has restricted access due to safety and operational requirements.

The 200-metre guyed mast is the tallest structure in the Loiret department and ranks among the tallest buildings in France. It carries EDF's COM TER transmissions and a TDF microwave beam, plus a 3 GHz WiMAX link operated by IFW.
