The Titahi Bay Transmitter, which until 16 February 2016 was New Zealand's second tallest structure, transmitted AM radio signals from a 220 metres tall radio mast insulated against ground at Titahi Bay in New Zealand. [1] The station which previously had three masts, now consists of only one mast with a height of 137 metres. [2] A third – smaller – mast with a height of 53 metres was toppled on 10 November 2015. The tower's surrounding buildings were opened in 1937. [3] Five radio programmes broadcast on four frequencies from the tower:[ citation needed ]
In 2004 the tower was refurnished, badly corroded parts were removed and replaced, the whole tower was sand-blasted and repainted, and an array of LED warning lights were added at the behest of the NZCAA.[ citation needed ]
According to workers refurbishing it, scaling the tower takes 45 minutes. From the top there are views of the entire Kapiti coast region.[ citation needed ]
The site formerly transmitted Radio New Zealand's shortwave service, these broadcasts used a series of shorter free-standing masts supporting curtain arrays.[ citation needed ]
Under the right conditions, the AM signal for National Radio can be received as far north as Norfolk Island and as far south as Dunedin.[ citation needed ]
The Department of Conservation owns the land surrounding the tower, which is leased to Radio NZ for the transmitting towers, to the local Titahi Golf Club, and as farm land. The site is located within Whitirea Park, and is planned to come under the control of the Greater Wellington Regional Council.[ citation needed ]

The site was never used for overseas telephone links, which (before the advent of undersea cables and satellites) were provided by two New Zealand Post Office radio stations, Makara Radio (receiving) west of Wellington and Himatangi radio station (transmitting) near Himatangi Beach. Only a limited number of voice circuits were available, and overseas toll calls were expensive.[ citation needed ]
On 14 October 2015, it was announced that the tallest tower (220 metres) would be removed by March 2016, due to health and safety concerns caused by corrosion issues. [4] The smallest tower (53 metres) was demolished on 10 November 2015. [5] On 16 February 2016, the tallest tower was demolished. [6]
The remaining 137m-high mast is now responsible for all transmitting duties.[ citation needed ]
OMEGA was the first global-range radio navigation system, operated by the United States in cooperation with six partner nations. It was a hyperbolic navigation system, enabling ships and aircraft to determine their position by receiving very low frequency (VLF) radio signals in the range 10 to 14 kHz, transmitted by a global network of eight fixed terrestrial radio beacons, using a navigation receiver unit. It became operational around 1971 and was shut down in 1997 in favour of the Global Positioning System.
The Warsaw Radio Mast was a radio mast located near Gąbin, Poland, and was the world's tallest structure at 2,120 ft from 1974 until its collapse on 8 August 1991. The mast was designed for extreme height in order to broadcast Communist propaganda around the world, including to the remotest areas such as Antarctica. As of 2023, it was the third-tallest manmade structure ever built, after the Burj Khalifa tower in the United Arab Emirates in 2009, and Merdeka 118 tower in Malaysia in 2022.

The Longwave transmitter Solec Kujawski is a longwave broadcasting facility of Polskie Radio on a frequency of 225 kHz frequency. Its construction was necessitated by the collapse of the Warsaw radio mast on 8 August 1991 and the resistance of the local population to its reconstruction. The height above sea level of the station is 67 metres (220 ft).
The longwave transmitter Raszyn is a longwave broadcasting transmitter near Raszyn, Poland. It was built in 1931 and rebuilt in 1949. The designer of the mast is unknown. It has been claimed that the rebuilt tower consists of sections from the radio mast of former Deutschlandsender Herzberg/Elster; however, there is no proof of this theory. The mast of the Raszyn longwave transmitter was, at inauguration, the second-tallest man-made structure on earth and until 1962, with a height of 335 metres, the tallest structure in Europe. The tower's height is 1,099 feet.
The Burghead transmitting station is a broadcasting facility near Burghead in Scotland for long wave and medium wave radio transmission that started service on 12 October 1936.

Nauen Transmitter Station in Nauen, Havelland district, Brandenburg, Germany, is the oldest continuously operating radio transmitting installation in the world. Germany's first high power radio transmitter, it was founded on 1 April 1906 by Telefunken corporation and operated as a longwave radiotelegraphy station through World War II, and during World War I became Germany's main link with the outside world when its submarine communications cables were cut. Upgraded with shortwave transmitters in the 1920s it was Germany's most advanced long range radio station, continually upgraded with the latest equipment and serving as an experimental station for Telefunken to test new technology. At the end of World War II, invading Russian troops dismantled and removed the transmitting equipment. During the Cold War it served as the GDR's international shortwave station Radio Berlin International (RBI), and was the East Bloc's second most powerful radio station, disseminating Communist propaganda to other countries. Since German Reunification in 1991 it has been operated by Deutsche Telekom, Germany's state telecommunication service. The original 1920 transmitter building designed by architect Herman Muthesius is still used; it is one of the many remaining buildings designed by that architect that is a protected cultural heritage site.
