Yintoni isiguquli sesatellite kwaye sisebenzela ntoni
Isiguquli sesathelayithi sibonelela ngolwamkelo lomqondiso obonakaliswa ukusuka kumphezulu we-eriyali kwaye idluliselwe kwimo ekhulisiwe kwi-tuner ye-TV yesathelayithi. Le yindlela entsonkothileyo ebandakanya imithetho esisiseko yefiziksi. Unokuthenga umguquleli onjalo ngexabiso elifikelelekayo.
Uphawu oluphambili lomguquli luyingxolo eyongezelelweyo, elinganiswa ngama-decibels. Xa kukho ingxolo encinane, umfanekiso weTV awugqwethwanga kakhulu.
Kwinzululwazi, isiguquli sichazwa njengomamkeli osebenza umqondiso wesathelayithi. Enyanisweni, kukho izixhobo ezimbini kwibhloko enye ye-monolithic. Isixhobo sokuqala sikhulisa isandi esifunyenwe kwisathelayithi. Yilapho inqanaba lengxolo eyongezelelweyo lidlala indima ephambili. Kumaxabiso aphantsi, kuya kubakho ukuphazamiseka okuncinci, – 0.3 – 0.5 dB.
Igama elithi LNB okanye ibhloko yengxolo ephantsi ikwanxulumene nesiguquli sesathelayithi.
Isixhobo sesibini siguqula amaza amaza. Ngoncedo lwabo, isignali idluliselwa kumamkeli okanye iTV ngokufikelela kude. Isitya sesathelayithi se-Offset silungele ukuhanjiswa komqondiso. Nantsi ingcaciso esisiseko yendlela esebenza ngayo yonke: Isiguquli, esibizwa ngokuchanekileyo ngakumbi nge-LNB, siyafuneka ukuze kuguqulwe amaza amaza “Ku” (10 … 13 GHz) okanye “C” uluhlu (3.5 … 4.5 GHz) ukuya ku-0.95 … 2.5 GHz, apho yenza ukuba kwenzeke ukuba umqondiso uhanjiswe kunye neelahleko ezincinci zentambo ukuya kumamkeli. Oku kwenza kube lula ukusebenzisa i-coaxial cable engabizi kwaye inike ubude ukuya kwi-20-30 yeemitha ukwenzela ukuba umqondiso ungalahleki. K\ Zonke iziguquli ziyahluka ngengxolo. Ukwahluka kwabo kukhulu ngenye indlela. Kukho abaguquleli balandelayo: [caption id = "attachment_3536" align = "aligncenter" wide = "250"]
Isiguquli senza uphawu olufunyenweyo lomelele. Oku kunceda ukubuyisela ilahleko kwintambo edibanisa i-eriyali kumamkeli. Umamkeli wongeza ingxolo yakhe kwisignali. Banamandla aqhubekayo. Isiginali yesathelayithi esuka kwi-eriyali iyodwa ayomelelanga, ngenxa yoko iba buthathaka ngaphakathi kwintambo, kungoko kufuneka yandiswe. Nangona kunjalo, isixhobo sazisa ingxolo yaso kwisignali, ngoko ke kubalulekile ukuba bancinci. Umguquleli unokuthengwa kwiimpawu ezahlukeneyo.
Zeziphi iintlobo zokuguqula izitya zesathelayithi ezikhoyo

Umgaqo wokusebenza komguquli wesathelayithi
Umguquleli uqokelela amaza, uwaguqule abe yimiqondiso yemvelaphi yombane, ehambisa umqondiso kumamkeli. Umguquleli we-LNB ubekwe kwindawo ekugxilwe kuyo kwi-eriyali, apho amaza agxininiswe khona. Isignali ikhuliswe kwi-converter, iguqulelwe kwi-frequency ephantsi. Ukudlulisa isignali ukusuka kwi-C okanye kwi-Ki ukuya kwi-L-band, udinga i-oscillator yendawo eyenza isignali yerediyo. Umxube unceda ukufumana umqondiso wesithathu, owumahluko wezo zimbini zokuqala. Ngenxa yoko, kuvela.
Kuluhlu lweKi, ngendlela echaseneyo, i-frequency oscillator yendawo ibalwa ukusuka kwi-frequency ye-signal efunyenwe kwi-satellite. Kukwakho nenye inkalo. Awukwazi ukutshintshela yonke i-Ki-band kwi-L-band. Ingaba umguquli une-oscillator enye yendawo kwaye ayifaki yonke i-Ki-band, okanye isignali yesathelayithi ingena kwi-L-band kuphela, i-bottom okanye phezulu koluhlu lubandakanyekayo. Uhlobo lwesibini lwabaguquleli luyinto yonke , ine-oscillators ye-2 yendawo, eyesibini ihlanganisa phezulu kwi-Ku. Uluhlu lutshintshwa kusetyenziswa isitshixo se-elektroniki esilawulwa ngumqondiso okhethekileyo. Ngaphakathi komguquli kukwakhiwa kwesinyithi. Ukuzaliswa kwesixhobo kufihliwe kwimeko yetsimbi, apho imveliso ye-F-connector ifakwe. Umguquleli unokuba nenani elahlukileyo leemveliso. Ngamanye amaxesha inani lifikelela kwisibhozo.
Uyijonga njani isiguquli ukuba sisebenze
Kulula kakhulu ukujonga isiguquli sokusebenza. Ukuba uneengxaki ngembono ye-TV yesiginali, kufuneka ubone ukuba umcimbi ukwi-converter ngokwenene. Okokuqala kufuneka uhlolisise ikhebula ukusuka kummkeli ukuya kwi-antenna ngeso, ukuba iphukile naphi na. Ukuba intambo ilungile, kufuneka uhlolisise intloko yesitya, ngoko oonxibelelwano kunye neengcingo, kukho inketho elula, oko kukuthi, tshintsha le ntloko kwaye ubone ukuba uphawu lutshintshile. Emva koko unokuqonda ukuba imbangela yengxaki ikwi-converter ephukileyo okanye kwenye i-node. Ungayikhetha njani intloko yesathelayithi kwaye ujonge isiguquli sesitya sesathelayithi ukuze usebenze, abaguquli besitya sesathelayithi abaneziphumo ezimbini, ezintathu kunye ezine: https://youtu.be/s6IW8HPgTEE
Indlela yokukhetha i-LNB, into omawuyijonge
Umfanekiso wengxolo yeyona parameter yokukhetha umguquli. Kubalulekile ukuqwalasela xa ukhetha uluhlu lwamaza, ingxolo yesigaba, isetyenziswa ngoku, i-polarity. Awona macandelo abalulekileyo ngumfanekiso wengxolo kunye nokuzuza. Ngendlela efanelekileyo, umzobo wengxolo kufuneka uboniswe kwi-package. 
Ukuba ayichazwanga, musa ukuthenga isixhobo. Ngelo xesha, nokuba i-coefficient ephantsi ayiqinisekisi ukuba umguquli uya kuba kumgangatho ophezulu. Le parameter ihlolwe kuphela kwilabhoratri. Ke ngoko, kungcono ukuthenga izixhobo kuphela kwezo ndawo ziye zavavanywa kwaye ziye zakwazi ukunika ingxelo entle ngokwazo. I-universal converter inokuthengwa ngexabiso eliphantsi kwi-Intanethi nakwiivenkile zerediyo. Le yeyona ndlela ilungileyo. Unokukhetha njani isiguquli sesathelayithi: https://youtu.be/nP7UpiEubro
Imifuziselo ethile
Isiguquli sesitya sesathelayithi esivela kwi-Tricolor sithandwa ngenxa yokuthembeka kwayo, kwaye ngaphandle koko, ungayithenga ngexabiso elifikelelekayo. Ayiyi kuba yindleko, kodwa iya kunika abanini bendlu uphawu oluphezulu.
Intloko yesathelayithi evela kwi-Tricolor [/ caption] Umabonakude wesathelayithi we-ALYNO unomguquli weC + Ku odityanisiweyo osekelwe kwiziguquli ezimbini. Inomphumo oxhomekeke “I-Ferret igxininise ngokuthe ngqo i-Twin-Twin”, ebonelela ngokufunyanwa kwesignali rhoqo kwiindidi ezimbini ngexesha elinye: C kunye ne-Ku. Isebenza kuphela kunye ne-passive multiswitch 4/2. Yenzelwe i-eriyali ezisezantsi. Polyethylene caps. ISathelayithi ngokubanzi GSLF-51E isiguquli esinobubanzi be-waveguide: 40 mm (umgangatho); uhlobo isinxibelelanisi: 75 F-uhlobo lukwathandwa phakathi kwababhalisi. Uguqulo lweGalaxy Innovations GI-301 sisetyhula polarization converter. Kulula kakhulu ukuyisebenzisa kubomi bemihla ngemihla.
Uyilo kunye nofakelo kwi-eriyali
Amaza kanomathotholo ombane awela esipilini. Ekubeni imilo yayo inesimo se-sphere, isignali, ewela kwindawo yesibuko, ibonakala kuphela kwicala elinye, i-boam yenziwa egxininiswe kwinqanaba elinye. Isixhobo esiyimfuneko sifakwe kwi “focus” – i-satellite converter ngokwayo. Lo mqadi uwe phezu kwakhe. Izinto eziphambili zomguquli yi-irradiator, i-waveguide ehamba ngayo umqondiso, iyunithi yombane eguqula amaza abe yi-pulses. Umguquli uguqula i-frequency, i-polarization, inika uphawu oluphezulu. Yenzelwe ukubukela umabonakude kumgangatho ophezulu.
Iimpazamo xa ukhetha kwaye ufaka, indlela yokuphepha ngayo
Umgangatho wetyala uhlala ukhethwa ngokungafanelekanga. Indawo yokusebenzela – isitalato. Ngexesha lokusetyenziswa, isixhobo sichaphazeleka ngokuguquguquka kobushushu. Ngoko ke, umzimba wesixhobo kufuneka ube kumgangatho ophezulu. Ukhuselo lwelanga olususekayo kufuneka luxhathise kwimitha. Ke ngoko, kufuneka uphinde ukhethe izinto ezikumgangatho ophezulu.
Kubalulekile! Ngayo nayiphi na i-depressurization yesixhobo, umswakama we-atmospheric uya kufika apho, okuya kubangela ukuphuka.
Umbala womzimba akufuneki uqaqambe, kungenjalo uya kutsala iintaka eziza kuchola iplastiki eqaqambileyo.
Ngaphambi kokuseta, kubalulekile ukubona ukuba isixhobo siyakwazi ukusebenza njani.
Kubalulekile! Isixhobo esisebenzayo sibonisa uphawu nokuba i-eriyali ayithunyelelwanga kwisathelayithi .
Imibuzo neempendulo
