The Beidweiler longwave transmitter is a high-power broadcasting transmission site owned by RTL Group and operated by RTL company Broadcasting Center Europe. It was used to transmit the French-speaking programme of RTL on longwave frequency 234 kHz until 1 January 2023. Based in Beidweiler, Luxembourg, the transmission site is situated at 49°43'58" N and 6°19'08" E and went into service in 1972 as replacement of the old Junglinster Longwave Transmitter. Junglinster remained in use as a backup site and for additional broadcast services.


The facility uses a directional antenna consisting of three 290-meter (950 ft) tall guyed masts, each equipped with a cage antenna. The output of this array is mostly directed toward Paris. When the site was inaugurated in 1972 it operated with a transmission power of 1400 kilowatts, which was pushed up to 2000 kW in 1974, making it one of the most powerful broadcasting stations in the world at the time.[1]


In 1994, the facility's transmitters were replaced with Thomson-Csf TRE 2175 units, which in turn were replaced by a new Transradio TRAM/P 1500 LS solid-state transmitter in 2011 that could support DRM digital radio broadcasting.[2] The maximum power of the site is 1500 kW (reduced to 1000 kW at night);[3] since 2020, the output power has been set to 750 kW daytime or 375 kW at night.[4]

In 2019, RTL Group and Luxembourgish energy company Enovos [lb] began work on an extensive solar generation facility at Beidweiler.[5] The first phase of the project, consisting of 16,100 photovoltaic solar panels, was connected to the national energy grid in 2020. A second group of panels went online in 2021. Together with a similar solar generation facility at Junglinster, the transmission sites make up the largest solar facility in Luxembourg, generating almost 10.5 gigawatt-hours of energy per year.[6]

In October 2022, RTL parent company Groupe M6 announced plans to cease broadcasting from the site, citing the need to reduce electricity consumption.[7] Transmissions from Beidweiler stopped on 2 January 2023, with listeners advised to switch to FM, DAB+, or streams delivered via digital TV and mobile apps.[8]
