Émetteur de l'aiguille du Midi, Telecommunications antenna at Aiguille du Midi summit in Chamonix-Mont-Blanc, France.

The Émetteur de l'aiguille du Midi is a 29-metre broadcasting tower and equipment building on the summit of the Aiguille du Midi, at 3842 metres the highest transmission site in France. Its lower cylinder is clad in greyish-white panels with a railing and small antenna; above it a narrower yellow-orange cylinder with horizontal seams ends in a grey tapered cap and a thin spike. A lower rectangular building with a grey metal roof stands beside it, linked by a walkway.

The broadcasting station was built by TDF to provide television and radio coverage across the mountainous regions of Haute-Savoie. It was created to reach the isolated Alpine valleys with modern communication signals.

The site broadcasts four public FM radio stations, including a local station for the Chamonix area. Mobile phone relays are not mounted on the tower itself but stand near the cable car arrival station, so the summit installation and the telephone coverage are separate.

The transmitter stands on the summit reached by the cable car from Chamonix; the mobile phone relays are not on the tower itself but near the cable car arrival station. The tower and its building sit on the rocky peak, so access is limited to the summit terraces open to cable car passengers.

The relays for mobile telephony and other transmissions are not mounted on the 29-metre tower itself but stand near the cable car's arrival station. The tower, operated by TDF, carries TNT television and four public FM stations, including the local station.
