New Zealand Masts
New Zealand Masts and Towers range in size from short flagpoles to high radio transmitter antenna structures. The highest mast is in Titahi Bay, being the highest structure in the Southern Hemisphere at time of construction. Later it became the highest in New Zealand and then later second to the Sky Tower in Auckland. Height * Skytower is tall, as measured from ground level to the top of the mast, making it the tallest free-standing structure in the Southern Hemisphere. *The radio mast of the Titahi Bay Transmitter is New Zealand's second tallest structure. The tower is tall, and owned by Radio New Zealand. The antenna is a 'guyed support' type, broadcasting at the low end of the medium wave AM radio broadcast band, 567 kHz, with 50 kilowatts of power. The AM radio transmitting antenna is a high structure, due to the height being a function of wavelength (station frequency). * television masts were built in many strategic locations (such as Waiatarua and Christc ...

Solid State (electronics)
Solid-state electronics means semiconductor electronics: electronic equipment using semiconductor devices such as transistors, diodes and integrated circuits (ICs). The term is also used as an adjective for devices in which semiconductor electronics that have no moving parts replace devices with moving parts, such as the solid-state relay in which transistor switches are used in place of a moving-arm electromechanical relay, or the solid-state drive (SSD) a type of semiconductor memory used in computers to replace hard disk drives, which store data on a rotating disk. History The term "solid-state" became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology based on the transistor, in which the electronic action of devices occurred in a solid state, from previous electronic equipment that used vacuum tubes, in which the electronic action occurred in a gaseous state. A semiconductor device works by controlling an electric current c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Mast
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. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guys. Broadcast engineers in the UK use the same terminology. A mast is a ground-based or rooftop structure that supports antennas at a height where they can satisfactorily send or receive radio waves. Typical masts are of steel lattice or tubular steel construction. Masts themselves play no part in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio New Zealand National
RNZ National ( mi, Te Reo Irirangi o Aotearoa Ā-Motu), formerly Radio New Zealand National, and known until 2007 as the National Programme or National Radio, is a publicly funded non-commercial New Zealand English-language radio network operated by Radio New Zealand. It specialises in programmes dedicated to news, the arts, music, and New Zealand culture generally, including some material in the Māori language. Historically the programme was broadcast on the (AM) "YA" stations 1YA, 2YA, 3YA and 4YA in the main centres. In 2013, RNZ National had a 10.3 per cent market share, the highest nationwide and up from 9.1 per cent in 2009. Market share peaked at 11.1 per cent in 2011, probably due to the station's coverage of the Christchurch earthquake. In 2014 493,000 people listened to RNZ National over the course of a week – the second-largest cumulative audience. A 2021 survey estimated 609,800 listeners (13.5% of the 10+ population), Morning Report being the most popular, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Kaukau
Mount Kaukau () is a large hill in the northern suburbs of Wellington, New Zealand near Johnsonville, Khandallah and Ngaio. The summit is 445 metres above sea level and is the most visible high point in the Wellington landscape further accentuated by Wellington's main television transmitter mast, which stands 122m from the summit. The city, harbour and the Remutaka and Tararua Ranges can be seen from the summit. On a clear day Mt. Tapuae-o-Uenuku and the Kaikoura Ranges in the South Island may be seen, whilst northwest is the Porirua Basin and the Tasman Sea. Name The hill's original name ''Tarikākā'' means 'where the parrots rested' and is shared with the nearby settlement in Ngaio at the base of the mountain. Before the clearing of the native totara forest on the slopes and general area, the native parrot kākā was common through the city. Over a hundred years later today, the population of kākā has begun to regenerate thanks mostly to the efforts at Zealandia, an ...

Cook Strait
Cook Strait ( mi, Te Moana-o-Raukawa) separates the North and South Islands of New Zealand. The strait connects the Tasman Sea on the northwest with the South Pacific Ocean on the southeast. It is wide at its narrowest point,McLintock, A H, Ed. (1966''Cook Strait''from An Encyclopaedia of New Zealand, updated 18-Sep-2007. Note: This is the distance between the North Island and Arapaoa Island; some sources give a slightly larger reading of around , that between the North Island and the South Island. and is considered one of the most dangerous and unpredictable waters in the world. Regular ferry services run across the strait between Picton in the Marlborough Sounds and Wellington. The strait is named after James Cook, the first European commander to sail through it, in 1770. In Māori it is named ''Te Moana-o-Raukawa'', which means ''The Sea of Raukawa''. Raukawa is a type of woody shrub native to New Zealand. History Approximately 18,000 years ago during the Last Gla ...

Wellington
Wellington ( mi, Te Whanganui-a-Tara or ) is the capital city of New Zealand. It is located at the south-western tip of the North Island, between Cook Strait and the Remutaka Range. Wellington is the second-largest city in New Zealand by metro area, and is the administrative centre of the Wellington Region. It is the world's southernmost capital of a sovereign state. Wellington features a temperate maritime climate, and is the world's windiest city by average wind speed. Legends recount that Kupe discovered and explored the region in about the 10th century, with initial settlement by Māori iwi such as Rangitāne and Muaūpoko. The disruptions of the Musket Wars led to them being overwhelmed by northern iwi such as Te Āti Awa by the early 19th century. Wellington's current form was originally designed by Captain William Mein Smith, the first Surveyor General for Edward Wakefield's New Zealand Company, in 1840. The Wellington urban area, which only includes urbanised ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
