Under a massive white fabric dome visible from the road along the Pink Granite Coast in northwest France, a 340-ton metal structure has stood still for forty years. Located in Pleumeur-Bodou, in the Côtes-d'Armor region, this structure, known as the PB1 horn antenna, played a pivotal role in capturing the first ever live television images transmitted by satellite between the United States and Europe. This historic event took place during the night of July 10 to 11, 1962, marking a major milestone in global communications. The PB1 antenna was part of a fierce technological race between France and Britain, which France won by just one minute in 1962. The construction of the antenna was an extraordinary engineering achievement. Weighing 340 tons, it was built using a special alloy of magnesium and aluminum, assembled with precision to the thousandth of a millimeter. The site was carefully chosen for its granitic ground and its western location, which helped minimize electrical interference. The antenna, 34 meters high and 54 meters long, was protected by a 64-meter-diameter dome made of a 2-millimeter thick fabric called Dracon, coated with synthetic rubber that allows radio waves to pass through. This dome, held up by internal pressure, enabled the antenna to rotate while shielding it from the strong winds of the Breton region. The satellite involved in this historic event was Telstar, a 77-kilogram sphere with a diameter of 87 centimeters. Telstar was equipped with 3,600 photovoltaic cells to power its operations and was launched on July 10, 1962, from Cape Canaveral in the United States. Three days before the launch, the PB1 horn antenna was fully operational. On July 11, 1962, at 0:47, the station successfully captured the first live television images transmitted between the Andover station in the U.S. and Pleumeur-Bodou, in front of 190 technicians. France was the first to receive these signals, just a few seconds ahead of the Goonhilly station in the United Kingdom. The PB1 horn antenna was inaugurated by French President Charles de Gaulle on October 19, 1962. However, it became obsolete in 1964 with the introduction of geostationary satellites, which remained fixed in position relative to Earth. The antenna was decommissioned in 1985 but was later classified as a historical monument and has undergone regular maintenance, including its 11th restoration campaign. Today, the structure is part of the Cité des télécoms, a telecommunications museum, and houses a tour that allows visitors to stand beneath the 340-ton alloy structure, frozen in the exact position where it received the first live satellite television images from America to Europe in July 1962.
