Lafayette transmitter

Lafayette transmitter was a large facility used for transatlantic VLF-transmission, located at Marcheprime, Aquitaine, France. The Lafayette transmitter used an antenna, which was carried by eight free-standing lattice towers (each 250 metres tall) with triangular cross-sections, which were the second tallest free-standing towers in the world. The 250-meter-high tripod pylons were supplied by Pitt-Des Moines Co steelworks in Pittsburgh, Pennsylvania and transported by water to Bordeaux. [1]

In 1944 the installations of Lafayette transmitter were destroyed by retreating German troops. The last of the towers was demolished in 1953.

Junglinster Longwave Transmitter

The Junglinster Longwave Transmitter is a longwave broadcasting facility used by RTL near Junglinster, Luxembourg, which went into service in 1932. Its aerial consists of three free-standing steel-framework towers, which are ground fed radiators. These towers formed a directional aerial for the frequency 234 kHz and until 1980 were 250 metres high. Since 1980 their height has been 215 metres.

Mühlacker radio transmitter

The Mühlacker Broadcasting Transmission Facility is a radio transmission facility near Mühlacker, Germany, first put into service on November 21, 1930. It uses two guyed steel tube masts as aerials and one guyed steel framework mast, which are insulated against ground. It has two transmission aerials for shortwave and one free standing steel framework tower for directional radio services. The shortwave transmitter was shut off on October 19, 2004. The medium wave transmitter was switched off in January 2012.

The Sottens Transmitter is the nationwide transmitter for French-speaking Switzerland. The transmitter is located at Sottens, Canton of Vaud, Switzerland. It is run on 765 kHz with a power of 600 kilowatts and is easily receivable during the night throughout the whole of Europe. Since 1989 the aerial used has been a centre-fed dipole fixed on the outside of a 188-metre-high grounded freestanding steel framework tower. Before 1989 a 190-metre high self-radiating, free standing steel framework tower was used as a transmission aerial. The Sottens transmitter most recently broadcast the Option Musique radio programme from Radio Suisse Romande, up until 5 December 2010.

Lakihegy Tower Historical radio tower in Hungary

The Lakihegy Tower is a 314-metre-high (1,031 ft) radio mast at Szigetszentmiklós-Lakihegy in Hungary. The Blaw-Knox type tower was built in 1933 and was one of Europe's tallest structures at the time of construction. It was designed to provide broadcast coverage for Hungary with a 120 kW transmitter. It was built for the purpose of transmitting the radio station "Budapest I.", which it served until 1977.

Żórawina radio transmitter

The Żórawina radio transmitter is a facility for FM transmission at Żórawina, south of Wrocław. It was established in 1932 as "Reichssender Breslau" and used as an antenna tower. Originally it was a 140-metre-tall free-standing lattice tower built of wood, on which a wire antenna was hung up. On the top of the tower there was an octagonal ring of bronze with a diameter of 10.6 metres for electrical lengthening of the antenna.

Wavre transmitter

The Wavre radio transmitter is a facility for Fm, Dab+ and TV broadcasting near Wavre in Belgium. Formerly the mediumwave transmissions used a grounded 250-metre-high guyed mast. Furthermore, there was a backup mast for medium wave transmissions, which was 90 metres high. For shortwave broadcasting there were several directional antennas and a curtain antenna.

Radio masts and towers Tall structure designed to support antennas

Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them.

RKS Liblice 2

The RKS Liblice 2 are two 355 m (1,165 ft) tall guyed masts located east of Prague near Liblice, in close proximity of the RKS Liblice 1. These lattice steel towers are built 120 m (390 ft) apart from each other, at which cage aerials are mounted. Designed by Jan Šťovíček, these supertall towers currently stand as the tallest towers in the world used for broadcasting in the medium-wave range. RKS Liblice-2 was built in 1976, and is currently used for broadcasting on 639 kHz. During construction, two new transmitter devices of the type Tesla SRV 750 with an output power of 750 KW were installed. In regular operation, these transmitters are switched in parallel for a transmission power of 1500 KW.
