The Sender Bielstein (Transmitter Bielstein) is an FM- and TV-broadcasting facility on the 393-metre-high Bielstein mountain in the Forest of Teutoburg, North Rhine-Westphalia, Germany.
Bielstein transmitter, which is the property of Westdeutscher Rundfunk and used for transmitting its programmes was established in 1951. It used until 1954 a 60-metre-tall mast. This mast was replaced in 1954 by a 102-metre-tall antenna tower. However this mast was not able to supply the whole area with FM and TV-programmes and so a taller antenna mast was soon planned. Finally in 1968 construction work started for a 298-metre-tall guyed steel tube mast. This mast, which was completed in 1970 enabled a satisfactory supply of FM- and TV-programmes in the area.
On January 15, 1985, at 6.26 MST as result of too much ice load and great wind-induced stress, one of the upper guys of the mast was torn off. As result the mast bent and cracked 160 metres above ground. Afterwards the rest of the mast collapsed as the falling upper parts destroyed the guys holding its lower parts. Already on the afternoon of that day as replacement for the first FM-transmitter which used the mast went on air again, by using a communication tower of Deutsche Telekom as the transmission site. Three days later, TV broadcasting was also restored. On Bielstein mountain, a temporary 85-metre-tall auxiliary transmission mast for transmitting the TV and FM-programmes was erected. Of course, reception of the signals radiated from this auxiliary mast was much worse than from the former 298 metre mast and so construction work for a new 302-metre-tall guyed lattice steel mast started, which was completed in August 1986.
In April 2006 the mast got a new antenna for DVB-T broadcasting, which reduced its height to 290 metres.

The Warsaw Radio Mast was a telecommunications tower located near the town of Gąbin, central Poland, and the world's tallest structure at 646.38 metres (2,120.7 ft) from 1974 until its collapse on 8 August 1991. It was the second tallest structure ever built, being surpassed as tallest by the Burj Khalifa, completed in 2009.
Sender Zehlendorf is a radio transmission facility which has been in service since 1936, when a short wave transmitter was built in Zehlendorf as part of the establishment of permanent radio services. This Zehlendorf site, which until the end of World War II was referred to as the Rehmate Radio Transmission Centre, had 26 different antennas.
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 Langenberg transmission tower is a broadcasting station that transmits MW, FM and TV signals. It is located in Langenberg, Velbert, Germany and has had a very turbulent history since its inauguration. The transmitter first went into service in 1927 with 60 kilowatts (kW) of power and a T-aerial hanging on two 100-metre freestanding steel-frame towers insulated against ground.
The Transmitter Hamburg-Billstedt is a broadcasting facility in Hamburg-Billstedt, established in 1934. It is owned and operated by the Norddeutscher Rundfunk public broadcasting service, but open to competitors, too.
The Transmitter Ismaning was a large radio transmitting station near Ismaning, Bavaria, Germany. It was inaugurated in 1932. From 1932 to 1934 this transmitter used a T-antenna as transmitting antenna, which was spun between two 115-metre-high free-standing wooden lattice towers, which were 240 metres apart. As this antenna had an unfavourable vertical radiation pattern, which produced much skywave resulting in a too small fading-free reception area at night, in 1934 a new antenna was installed. Therefore, one of the towers was dismantled and rebuilt on a 39-metre-high (128 ft) wooden lattice base. While this work took place, an L-Antenna was used, which was spun between the other tower and a small auxiliary wooden tower. It became defunct in 1977 and was destroyed in 1983.
The Rheinsender is a large medium-wave transmission facility near Wolfsheim, southwest of Mainz for the frequency 1017 kHz. The Rhine transmitter was established in 1950 and went on the air May 15, 1950. It belongs to SWR and transmitted until the middle of the 1990s with 600 kilowatts. In the last years the transmission power was reduced to 100 kilowatts.
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.
The Tacolneston transmitting station is a facility for both analogue and digital VHF/FM radio and UHF television transmission near Tacolneston, 11 miles (18 km) south-west of Norwich, Norfolk, England.
The Lichfield transmitting station is situated close to Tamworth in Staffordshire in the West Midlands between the A5 and A51. The nearest geographical feature is Hopwas Hill. The station is owned and operated by Arqiva. The mast is known locally as Hopwas mast or Hints mast.
The Wiederau transmitter is the oldest broadcasting facility in Saxony. It is located near Wiederau, a village which is part of the municipality of Pegau, and is used for medium-wave, FM and Television broadcasting.
Marnach transmitter was a broadcasting facility of RTL near Marnach in the commune of Munshausen, in northern Luxembourg. The Marnach transmitter was built in 1955 for improving the transmission of the English-speaking program on 1439 kHz, which was transmitted from 1951 with an omnidirectional antenna from Junglinster, to the British Isles and for a better transmission on this frequency to Germany at daytime. Therefore, it was given a directional antenna with a switchable directional characteristic pointing North-northeast towards the Rhine-Ruhr area, Germany's most populated area, and West-northwest in the direction of the UK. This antenna was implemented in form of a directional antenna consisting of three ground-fed 105-metre tall guyed mast antennas arranged in the form of an isosceles triangle with a 90 degree angle. As transmitters, two 100 kW units switched in parallel were used when it went in service in December 1955.
