74-515: A radome (a portmanteau of " radar " and " dome ") is a structural, weatherproof enclosure that protects a radar antenna . The radome is constructed of material transparent to radio waves. Radomes protect the antenna from weather and conceal antenna electronic equipment from view. They also protect nearby personnel from being accidentally struck by quickly rotating antennas. Radomes can be constructed in several shapes – spherical, geodesic , planar, etc. – depending on

148-426: A compound , which fully preserves the stems of the original words. The British lecturer Valerie Adams's 1973 Introduction to Modern English Word-Formation explains that "In words such as motel ..., hotel is represented by various shorter substitutes – ‑otel ... – which I shall call splinters. Words containing splinters I shall call blends". Thus, at least one of the parts of a blend, strictly speaking,

222-438: A coaxial cable that connected to the microwave radio station at Hunters Stones , which was part of the long-distance telephone network. This connection was replaced in 1992 by a new high capacity fibre-optic cable. Later, two additional cables were added over which telephone and other communications could go to and from the base. These cables were capable of transmitting over 100,000 phone calls simultaneously. On 1 October 2000,

296-523: A form suitable for carrying on horseback; (now esp.) one in the form of a stiff leather case hinged at the back to open into two equal parts". According to The American Heritage Dictionary of the English Language ( AHD ), the etymology of the word is the French porte-manteau , from porter , "to carry", and manteau , "cloak" (from Old French mantel , from Latin mantellum ). According to

370-437: A full debate about missile defence and Menwith Hill. Actions continue into 2006. One particular local activist, Lindis Percy , was prosecuted, over a protracted period, under a number of different laws. In April 2012 activists affiliated with the global Occupy Movement held a four-day campsite at Menwith Hill. Protesters said they hoped the camp would "reignite the debate locally, nationally and globally about whether

444-482: A headquarters building, barracks, dependent housing and support facilities such as a cinema and social clubs. The operations building was located inside a secure compound, within a large antenna field, approximately 1.6 kilometres (0.99 mi) from the main site. It was equipped with large high frequency (HF) directional rhombic antennas that could detect signals from around the globe. Over two-hundred Collins R-390A HF communications receivers were used to collect

518-427: A kind of bath), the attributive blends of English are mostly head-final and mostly endocentric . As an example of an exocentric attributive blend, Fruitopia may metaphorically take the buyer to a fruity utopia (and not a utopian fruit); however, it is not a utopia but a drink. Coordinate blends (also called associative or portmanteau blends) combine two words having equal status, and have two heads. Thus brunch

592-578: A number of peace camps were established in close proximity to the station. A number of other individual protests have also taken place, predominantly related to nuclear proliferation and strategic missile defense. Protests also occurred at other US military locations in the UK such as Greenham Common . Objections to the Strategic Defense Initiative have led to demonstrators storming the perimeter fence, and to demands in 2007 from Labour MPs for

666-506: A radome is not necessary. An example of this is the pyramid which replaced the golfball-style radome installations at RAF Fylingdales . Portmanteau In linguistics , a blend —also known as a blend word , lexical blend , or portmanteau —is a word formed by combining the meanings, and parts of the sounds, of two or more words together. English examples include smog , coined by blending smoke and fog , as well as motel , from motor ( motorist ) and hotel . A blend

740-757: A report commissioned by STOA concerning the ECHELON system, at a "hearing of the Committee on Citizens Freedoms and Rights, Justice and Home Affairs on the subject the European Union and data protection" which prompted the European Union to set up the Temporary Committee on the ECHELON Interception System . On 5 July 2000, the European Union set up the European Parliament 's Temporary Committee on

814-481: A total blend, each of the words creating the blend is reduced to a mere splinter. Some linguists limit blends to these (perhaps with additional conditions): for example, Ingo Plag considers "proper blends" to be total blends that semantically are coordinate, the remainder being "shortened compounds". Commonly for English blends, the beginning of one word is followed by the end of another: Much less commonly in English,

888-585: A vast range of signal in the HF band, including carrier waves , voice signals, and burst transmissions . Within the operations centre was the communications centre which was staffed by cryptographers using deciphering equipment, however a large amount of the signals collected were encrypted before being forwarded for processing to the US National Security Agency's Fort Meade facility in Maryland . In

RAF Menwith Hill Royal Air Force Menwith Hill ( RAF Menwith Hill ) is a Royal Air Force station near Harrogate , North Yorkshire, England, which provides communications and intelligence support services to the United Kingdom and the United States . The site contains an extensive satellite ground station and

1036-622: Is a communications intercept and missile warning site. It has been described as the largest electronic monitoring station in the world. RAF Menwith Hill is owned by the Ministry of Defence (MoD), but made available to the US Department of Defense (DoD) under the NATO Status of Forces Agreement 1951 and other, undisclosed agreements between the US and British governments. His Majesty's Government (HMG)

1110-477: Is a Japanese blend that has entered the English language. The Vietnamese language also encourages blend words formed from Sino-Vietnamese vocabulary . For example, the term Việt Cộng is derived from the first syllables of "Việt Nam" (Vietnam) and "Cộng sản" (communist). Many corporate brand names , trademarks, and initiatives, as well as names of corporations and organizations themselves, are blends. For example, Wiktionary , one of Misplaced Pages 's sister projects,

1184-489: Is a blend of wiki and dictionary . The word portmanteau was introduced in this sense by Lewis Carroll in the book Through the Looking-Glass (1871), where Humpty Dumpty explains to Alice the coinage of unusual words used in " Jabberwocky ". Slithy means "slimy and lithe" and mimsy means "miserable and flimsy". Humpty Dumpty explains to Alice the practice of combining words in various ways, comparing it to

1258-440: Is both phonological and orthographic, but with no other shortening: The overlap may be both phonological and orthographic, and with some additional shortening to at least one of the ingredients: Such an overlap may be discontinuous: These are also termed imperfect blends. It can occur with three components: The phonological overlap need not also be orthographic: If the phonological but non-orthographic overlap encompasses

1332-412: Is entitled to possession of the site and retains control over its use and its facilities, though the administration of the base is the responsibility of the US authorities, with support provided by around 400 staff from Government Communications Headquarters (GCHQ), in addition to United States Air Force (USAF) and US National Security Agency (NSA) personnel. In 2014, the number of American personnel

1406-692: Is neither a breakfasty lunch nor a lunchtime breakfast but instead some hybrid of breakfast and lunch; Oxbridge is equally Oxford and Cambridge universities. This too parallels (conventional, non-blend) compounds: an actor–director is equally an actor and a director. Two kinds of coordinate blends are particularly conspicuous: those that combine (near‑) synonyms: and those that combine (near‑) opposites: Blending can also apply to roots rather than words, for instance in Israeli Hebrew : "There are two possible etymological analyses for Israeli Hebrew כספר kaspár 'bank clerk, teller'. The first

1480-664: Is not a complete morpheme , but instead a mere splinter or leftover word fragment. For instance, starfish is a compound, not a blend, of star and fish , as it includes both words in full. However, if it were called a " stish " or a " starsh ", it would be a blend. Furthermore, when blends are formed by shortening established compounds or phrases, they can be considered clipped compounds , such as romcom for romantic comedy . Blends of two or more words may be classified from each of three viewpoints: morphotactic, morphonological, and morphosemantic. Blends may be classified morphotactically into two kinds: total and partial . In

1554-405: Is often used to prevent ice and freezing rain from accumulating on antennas. In the case of a spinning radar parabolic antenna , the radome also protects the antenna from debris and rotational irregularities due to wind. Its shape is easily identified by its hardshell, which has strong properties against being damaged. For stationary antennas, excessive amounts of ice can de- tune the antenna to

1628-606: Is one of three main sites operated by the United States across the globe as a major satellite monitoring station and intelligence gathering location. The other two sites are located in America and Australia, having similar roles and working together with RAF Menwith Hill to develop knowledge around American, British and Australian interests. The Australian site is known as the Joint Defence Facility Pine Gap . In 1954,

1702-471: Is provided by the Ministry of Defence Police (MDP). One of three MDP Central Support Group units is based at Menwith Hill, providing armed officers who can be deployed regionally at short notice, to support wider MDP operations. On 1 April 2006, RAF Menwith Hill was designated as a protected site for the purposes of Section 128 of the Serious Organised Crime and Police Act 2005 . The effect of

1776-452: Is similar to a contraction . On the one hand, mainstream blends tend to be formed at a particular historical moment followed by a rapid rise in popularity. Contractions, on the other hand, are formed by the gradual drifting together of words over time due to them commonly appearing together in sequence, such as do not naturally becoming don't (phonologically, / d uː n ɒ t / becoming / d oʊ n t / ). A blend also differs from

1850-405: Is that it consists of (Hebrew>) Israeli כסף késef 'money' and the ( International /Hebrew>) Israeli agentive suffix ר- -ár . The second is that it is a quasi- portmanteau word which blends כסף késef 'money' and (Hebrew>) Israeli ספר √spr 'count'. Israeli Hebrew כספר kaspár started as a brand name but soon entered the common language. Even if the second analysis is the correct one,

1924-668: The 501st Combat Support Wing , both of which have their headquarters at RAF Alconbury in Cambridgeshire . According to the Royal Air Force "RAF Menwith Hill is an integral part of the US DOD world-wide defence communications network. Its primary mission is to provide intelligence support for UK, US and allied interests." The site is a field station of the US National Security Agency (NSA), with personnel from other parts of

1998-520: The OED Online , the etymology of the word is the "officer who carries the mantle of a person in a high position (1507 in Middle French), case or bag for carrying clothing (1547), clothes rack (1640)". In modern French, a porte-manteau is a clothes valet , a coat-tree or similar article of furniture for hanging up jackets, hats, umbrellas and the like. An occasional synonym for "portmanteau word"

2072-479: The nose cones often additionally serve as radomes. On airborne early warning and control (AEW&C) aircraft (e.g. the American E-3 Sentry ), a discus -shaped rotating radome, often called a " rotodome ", is mounted on the top of the fuselage for 360-degree scanning coverage. Some newer AEW&C configurations instead use three 120-degree phased array modules inside a stationary radome, examples being

2146-407: The 1951 NATO Status of Forces Agreement and other classified arrangements. The MOD retains control over the site's use and facilities, however the administration of the site is the responsibility of the US authorities. The US Air Force's 421st Air Base Squadron provides Menwith Hill with base and mission support services. The squadron is part of the 423rd Air Base Group which in turn is part of

2220-587: The 1960s, as a result of developments in digital technology and the increased use of satellites for signals intelligence, the specialist skills of engineers and technicians within the National Security Agency (NSA) and their contractors became increasingly important. Therefore, on 1 August 1966, with the agreement of the British Government, control of Menwith Hill Station was handed from the US Army to

2294-478: The 451st Intelligence Squadron was re-designated as the 451st Information Operations Squadron, before reverting to the 451st Intelligence Squadron on 1   April 2007. On 19   July 2002, US Army INSCOM transferred responsibility for administrative and logistical support for Menwith Hill to the US Air Force , to bring the site in-line with other facilities in the UK made available to the US. Notwithstanding,

They confirmed that Menwith Hill was "linked directly to the headquarters of the US National Security Agency (NSA) at Fort Meade in Maryland." Between 1984 and 1995

2442-547: The British War Office purchased 246 acres (100 hectares) of land at Nessfield Farm, located approximately 7 kilometres (4.3 mi) west of Harrogate , North Yorkshire. The area purchased soon increased to 562 acres (227 hectares) and were made available by the British Government to the United States Department of Defense . The site was considered by the US as suitable for gathering signals intelligence from

2516-628: The British and US governments. Investigations found that during the early 1960s, Menwith Hill was integrated into the General Post Office's microwave relay network known as ' Backbone ', via a high-capacity underground cable link to the Hunters Stones communications tower, located approximately 3 miles (4.8 km) to the south of the station. It was alleged the link allowed mass interception of civilian telephone and telex communications between

2590-564: The Chinese KJ-2000 and Indian DRDO AEW&Cs . On fixed-wing and rotary-wing aircraft using microwave satellite for beyond-line-of-sight communication , radomes often appear as bulged "blisters" on the fuselage. The use of radomes dates back as far as 1941. The air supported radome built by Walter Bird in 1948 at the Cornell Aeronautical Laboratory is the first pneumatic construction built in history. A radome

2664-667: The Columbus Division of North American Aviation. This radome was originally used for the FPS-35 search radar at Baker Air Force Station, Oregon. When Baker AFS was closed the radome was moved to provide a high-school gymnasium in Payette, Idaho. Pictures and documents are available online at radomes.org/museum for Baker AFS/821st Radar Squadron. For maritime satellite communications service, radomes are widely used to protect dish antennas which are continually tracking fixed satellites while

2738-629: The DOD also present. UK personnel from the MOD and Government Communications Headquarters (GCHQ) are integrated into both the operational and administrative elements of the site. In November 2017, the British Government advised that 1,205 personnel worked at the station, comprising 33 staff from the US military , 344 US contractors, 250 US civilians, 7 UK military (5 Royal Navy and 2 RAF), 85 UK contractors and 486 UK civilians (including those employed by GCHQ). Site security

2812-501: The ECHELON Interception System stated that the global system for the interception of private and commercial communications was operating by means of "cooperation proportionate to their capabilities" among the US, the UK, Canada, Australia and New Zealand under the UKUSA. ... It seems likely ... that its name is in fact ECHELON." The Committee raised concerns about the incompatibility of the interception of private and commercial communications with

2886-617: The European Parliament. In 1996 author and investigative journalist, Nicky Hager in his book entitled Secret Power: New Zealand's Role in the International Spy Network , provided a detailed account of ECHELON, the worldwide electronic surveillance system used by an intelligence alliance of the United States, the United Kingdom, Canada, Australia and New Zealand. On 3 November 1999, the BBC reported that they had confirmation from

2960-501: The NSA when it became a field element of the agency. The NSA expanded the station during the 1970s and 1980s, with the operations centre extended and new buildings erected. The first two radomes , designed to protect satellite receiver and transmission dishes (colloquially known as ' golf balls ' and now synonymous with the station) were installed in 1974, at which point around 800 personnel were believed to work there. In 1976, 21 years after

During the 2009 G-20 London Summit NSA intercept specialists based at Menwith Hill attempted to target and decode the encrypted telephone calls of the Russian president Dmitry Medvedev . The 451st Intelligence Squadron, was inactivated on 24 June 2015. In November 2017, the site had 627 US staff and 578 UK staff. Planning permission was granted in August 2019 for the construction of three new radomes at

3108-399: The UK and sometimes to the US". The suggestion that national and international communications were monitored was denied. A detachment of the US Army 704th Military Intelligence (MI) Brigade was established at Menwith Hill in 1985. In 1992, the detachment became A Company of the 743rd Military Intelligence Battalion, 704th MI Brigade. The US Air Force's 6951st Electronic Security Squadron

3182-499: The US Army retained a presence and in place of the 109th Military Intelligence Group, INSCOM formed a provisional battalion designated as the Menwith Hill Battalion (Provisional). On 18 October 2008 the unit, under the command of a lieutenant colonel , was re-designated as the 307th Military Intelligence Battalion, subordinate to the 66th Military Intelligence Brigade headquartered at Wiesbaden , Germany. On 16 October 2009,

3256-427: The United States, UK and Europe. At the time, eight radomes were now present at Menwith Hill, connecting it with other sites in the NSA's satellite communications network and alleged to allow the surveillance of communications in foreign countries. In response to the article the NSA said "We do radio relays - material comes in from a variety of places and is rerouted. It is a switching operation. We route it sometimes to

3330-486: The Yorkshire Campaign for Nuclear Disarmament (CND). Menwith Hill's primary mission is to provide "intelligence support for UK, US and allied interests". The base's multimillion-pound expansion, Project Phoenix, is "one of the largest and most sophisticated high technology programs carried out anywhere in the UK over the last 10 years". Of the 1,800 employees in 2012, 400 were British and 1,200 were American employees of

3404-619: The act was to make it a specific criminal offence for a person to trespass into the station. In 1988, investigative journalist Duncan Campbell revealed, in an article entitled "Somebody's listening" and published in New Statesman , the existence of the ECHELON surveillance program, an extension of the UKUSA Agreement on global signals intelligence Sigint . He also detailed how the eavesdropping operations worked. Duncan Campbell presented

3478-460: The antenna's exposed parts with a sturdy, weatherproof material, typically fiberglass, keeping debris or ice away from the antenna, thus preventing any serious issues. One of the main driving forces behind the development of fiberglass as a structural material was the need during World War II for radomes. When considering structural load, the use of a radome greatly reduces wind load in both normal and iced conditions. Many tower sites require or prefer

3552-535: The battalion was re-designated as the 709th Military Intelligence Battalion. According to an article in a 2003 issue of an internal NSA newsletter, "Menwith is a large site (several hundred NSA civilians)". In March 2012 researcher Steve Schofield of BASIC produced a 65-page report called "Lifting the Lid on Menwith Hill", funded by the Joseph Rowntree Charitable Trust and commissioned and published by

3626-502: The beginning of one word may be followed by the beginning of another: Some linguists do not regard beginning+beginning concatenations as blends, instead calling them complex clippings, clipping compounds or clipped compounds . Unusually in English, the end of one word may be followed by the end of another: A splinter of one word may replace part of another, as in three coined by Lewis Carroll in " Jabberwocky ": They are sometimes termed intercalative blends; these words are among

3700-456: The contiguous United States and Alaska during the Cold War. Most of the radars used at these ground stations were protected by rigid or inflatable radomes. The radomes were typically at least 15 m (50 ft) in diameter and the radomes were attached to standardized radar tower buildings that housed the radar transmitter, receiver and antenna. Some of these radomes were very large. The CW-620

3774-586: The final syllable ר- -ár apparently facilitated nativization since it was regarded as the Hebrew suffix ר- -år (probably of Persian pedigree), which usually refers to craftsmen and professionals, for instance as in Mendele Mocher Sforim 's coinage סמרטוטר smartutár 'rag-dealer'." Blending may occur with an error in lexical selection , the process by which a speaker uses his semantic knowledge to choose words. Lewis Carroll's explanation, which gave rise to

They were also concerned that interception of commercial communications could be used for "competitive intelligence-gathering rather than combating corruption." During the early 1970s, the first of what became more than eight large satellite communications dishes were installed at Menwith Hill. In 1999 he wrote a report on COMINT entitled Interception Capabilities 2000 for

3922-485: The group added a second company and was re-designated as the 109th Military Intelligence Group. On 19 February 1996, the station was renamed RAF Menwith Hill, an administrative change to align the base with other sites made available to the United States by the United Kingdom. During a 1997 court case, British Telecom revealed that in 1975, its predecessor, the Post Office, installed two cables between Menwith Hill and

3996-403: The ingredients is the head and the other is attributive. A porta-light is a portable light, not a 'light-emitting' or light portability; light is the head. A snobject is a snobbery-satisfying object and not an objective or other kind of snob; object is the head. As is also true for (conventional, non-blend) attributive compounds (among which bathroom , for example, is a kind of room, not

4070-409: The initial tenure arrangements were agreed with the US, the British Government renewed assurances that the site would continue to be available for a further 21 years. Menwith Hill came to public attention in 1980 when British magazine the New Statesman published an article which suggested that the station was the world's largest phone tapping facility and highlighted the secrecy afforded to it by

4144-490: The morphemes or phonemes stay in the same position within the syllable. Some languages, like Japanese , encourage the shortening and merging of borrowed foreign words (as in gairaigo ), because they are long or difficult to pronounce in the target language. For example, karaoke , a combination of the Japanese word kara (meaning empty ) and the clipped form oke of the English loanword "orchestra" (J. ōkesutora , オーケストラ ),

4218-659: The northern parts of Western Europe and Eastern Europe , specifically the Soviet Union and its associated Warsaw Pact countries. The Yorkshire Dales' low level of background radio noise made it an especially good location for the task. The UK provided assurances to the US that the site would be available to them for at least 21 years. Construction of the station on behalf of the United States Army Security Agency (USASA) began in April 1956. Building costs at

4292-495: The original "portmanteaus" for which this meaning of the word was created. In a partial blend, one entire word is concatenated with a splinter from another. Some linguists do not recognize these as blends. An entire word may be followed by a splinter: A splinter may be followed by an entire word: An entire word may replace part of another: These have also been called sandwich words, and classed among intercalative blends. (When two words are combined in their entirety,

4366-412: The particular application, using various construction materials such as fiberglass , polytetrafluoroethylene (PTFE) -coated fabric, and others. In addition to radar protection, radomes on aircraft platforms also act as fairings that streamline the antenna system, thus reducing drag . When found on fixed-wing aircraft with forward-looking radar, as are commonly used for object or weather detection,

4440-430: The point where its impedance at the input frequency rises drastically, causing the voltage standing wave ratio (VSWR) to rise as well. This reflected power goes back to the transmitter , where it can cause overheating . A foldback circuit can act to prevent this; however, one drawback of its use is that it causes the station's output power to drop dramatically, reducing its range. A radome avoids that by covering

4514-453: The result is considered a compound word rather than a blend. For example, bagpipe is a compound, not a blend, of bag and pipe. ) Morphologically, blends fall into two kinds: overlapping and non-overlapping . Overlapping blends are those for which the ingredients' consonants, vowels or even syllables overlap to some extent. The overlap can be of different kinds. These are also called haplologic blends. There may be an overlap that

4588-619: The rotational mechanism and the sensitive electronics , and is heated in colder climates to prevent icing. The RAF Menwith Hill electronic surveillance base, which includes over 30 radomes, is widely believed to regularly intercept satellite communications. At Menwith Hill, the radome enclosures prevent observers from seeing the direction of the antennas, and therefore which satellites are being targeted. Similarly, radomes prevent observation of antennas used in ECHELON facilities. The United States Air Force Aerospace Defense Command operated and maintained dozens of air defense radar stations in

4662-675: The ship experiences pitch, roll and yaw movements. Large cruise ships and oil tankers may have radomes over 3   m in diameter covering antennas for broadband transmissions for television, voice, data, and the Internet, while recent developments allow similar services from smaller installations such as the 85 cm motorised dish used in the SES Broadband for Maritime system. Small private yachts may use radomes as small as 26   cm in diameter for voice and low-speed data. An active electronically scanned array radar has no moving antenna and so

Extension of the site means that it now covers 605 acres (245 ha). RAF Menwith Hill is owned by the British Ministry of Defence (MOD). Although designated as an RAF station, it is made available to the United States Department of Defense (DOD) under

Initially named Field Station 8613 , the site was renamed 13th USASA Field Station on 1 January 1957 and again renamed on 1 January 1959, as Menwith Hill Station . Due to adverse ground conditions and weather, there were delays to the construction programme, with the station finally becoming operational during June 1959. Operationally, Menwith Hill

4958-462: The two words "fuming" and "furious". Make up your mind that you will say both words, but leave it unsettled which you will say first … if you have the rarest of gifts, a perfectly balanced mind, you will say "frumious". In then-contemporary English, a portmanteau was a suitcase that opened into two equal sections. According to the OED Online , a portmanteau is a "case or bag for carrying clothing and other belongings when travelling; (originally) one of

5032-406: The use of 'portmanteau' for such combinations, was: Humpty Dumpty's theory, of two meanings packed into one word like a portmanteau, seems to me the right explanation for all. For instance, take the two words "fuming" and "furious." Make up your mind that you will say both words ... you will say "frumious." The errors are based on similarity of meanings, rather than phonological similarities, and

5106-426: The use of radomes for wind loading benefits and for protection from falling ice or debris. Where radomes might be considered unsightly if near the ground, electric antenna heaters could be used instead. Usually running on direct current , the heaters do not interfere physically or electrically with the alternating current of the radio transmission . For radar dishes, a single, large, ball-shaped dome also protects

5180-542: The whole of the shorter ingredient, as in then the effect depends on orthography alone. (They are also called orthographic blends. ) An orthographic overlap need not also be phonological: For some linguists, an overlap is a condition for a blend. Non-overlapping blends (also called substitution blends) have no overlap, whether phonological or orthographic: Morphosemantically, blends fall into two kinds: attributive and coordinate . Attributive blends (also called syntactic or telescope blends) are those in which one of

Security at the station was provided by a US Army military police detachment and the British Air Ministry Constabulary . However, if the site was compromised during an invasion, three earth-covered bunkers contained ammunition and thermite charges which could be used to destroy classified equipment and material.
