Efasiteleni elikhethekile, khetha i-satellite lapho kuzokwenziwa khona isiqondiso, esimweni sethu i-Express AM3.
Chofoza inkinobho ye-pop-up “Bala i-Azimuth nokuphakama”.
Sithola idatha edingekayo.
Kukhona enye ipharamitha endaweni yolwazi – “Ukuzungeza kwe-Converter”, lena ipharamitha ebalulekile, okuningi ngayo kuzochazwa esigabeni sokufakwa kwe-antenna.
Ukukhetha indawo yokufaka
Lapho ufaka uthi, kufanele ugxile ezintweni ezintathu ezibalulekile.
- Indawo evuleke kakhulu ekuqondeni kwesathelayithi , ngokufanelekile umugqa oqondile wokubuka, ongavinjwanga izakhiwo, izihlahla, amagquma e-landscape. [i-id yamagama-ncazo = “okunamathiselwe_3472″ align=”aligncenter” wide=”450″]
Ukukhetha indawo efanele yokufaka isitsha sesathelayithi kuwumsebenzi wokuqala[/caption] - Ukuthembeka kokukhwezwa kwe-antenna . Njengomthetho, isibuko sesitsha sesathelayithi, ngenxa yezici zokuklama, sinomoya okhulayo futhi, uma singaqinisiwe ngokuphephile, sizosuka emoyeni.
- Gcina ibanga ukusuka othini ukuya kumamukeli wesathelayithi lifushane ngangokunokwenzeka . Iqiniso liwukuthi noma iyiphi ikhebula ingenisa i-coefficient yayo yokunciphisa – okungukuthi, yehlisa izinga lesiginali ewusizo. Mayelana nalokhu, ngisho nalapho usebenzisa ikhebula lekhwalithi ephezulu, akunconywa ukususa i-antenna kude nomamukeli ngamamitha angaphezu kuka-20-25.
Indawo yokukhweza ekhethiwe kufanele futhi inikeze amandla okuzungezisa isibuko se-antenna ngamadigri ayi-10-14 ukusuka ku-azimuth axis. Uma kukhona isithiyo semvelo (sokufakelwa) esiqondisweni sesathelayithi ebangeni elincane, ungazama ukucacisa izinga lethonya layo elingenzeka kwikhwalithi yokwamukela.
Ukuze ubale, kuyadingeka ukuthi unqume cishe ibanga lento kanye nokuphakama kwayo (isibonelo, ngokuqhathanisa ubude bezinto eziseduze nokuphakama okwaziwayo), bese usebenzisa ukubala kwe-trigonometric noma noma yiziphi izinsizakalo ze-Intanethi, bala i-engeli yokuphakama entweni. Uma inani elitholiwe lingadluli inani le-engeli yokuphakama (ukuphakama), ngakho-ke akukho lutho lokukhathazeka ngakho, ngaphandle kwalokho udinga ukukhetha enye indawo yokufaka i-antenna noma usebenzise ukusekela ukwandisa ukuphakama.
Ukunquma izixhumanisi zendawo yakho zokufaka isitsha sesathelayithi – le datha iyadingeka ukuze kubalwe i-azimuth kanye ne-engeli yokuphakama yesitsha sesathelayithi kusetshenziswa isibali noma isofthiwe ekhethekile:

Ukufakwa kwemishini ye-antenna
Inqubo yokufaka i-antenna iqala ngokuhlangana kwayo. Lapho uhlanganisa, udinga ukugxila ezincomo zomenzi. Njengomthetho, i-antenna iza nemiyalelo enemininingwane yokuyihlanganisa, ekhombisa imingcele esemqoka. [i-id yamagama-ncazo = “okunamathiselwe_3466″ align=”aligncenter” width=”540″]
Ukufakwa kwesitsha sesathelayithi[/caption] Uthi oluhlanganiswe kahle lufakwa kusisekelo esifakwe ngaphambili nesiqinisiwe, kuyilapho ukuxhumana okuboshiwe kunomthwalo wemfanelo wokuzungezisa. isibuko se-antenna ezindizeni eziqondile nezivundlile aziqini yonke indlela. Ukufakwa kwesiguquli kufanelwe amagama akhethekile
. Isiguquli sibekwe endaweni okugxiliswe kuyo i-antenna ehlanganiswe ngokugcwele futhi sizungeziswa enanini le-engeli elitholwe ohlelweni lwe-Satcalc esigabeni sokubala i-azimuth ne-engeli yokuphakama. Inani elikukholomu Yokuzungezisa i-LNB libonisa ukuthi i-LNB idinga ukuzungeziswa ngamadigri angu-46 ngokuphikisana newashi ukusuka mpo. Ukuze kube lula ukusetha i-engeli, izimpawu zisetshenziswa ngaphambili kwesiguquli okubonisa “isikhundla sikaziro” nesikali se-angular. Isinyathelo sokugcina sokukhweza uthi ukuxhuma ikhebula kusiguquli esinelebula.
Ukushuna kwe-antenna
Izitsha zesathelayithi zihlukaniswe ngokuthi “Direct Focus” kanye “Offset”. Ungazihlukanisa zombili ngokufunda imibhalo enamathiselwe, futhi ngokubukeka – okugxilwe ngqo kunokucushwa okuyindilinga, isibuko sama-antenna e-offset sinomumo we-ellipse (side kakhudlwana ohlangothini lwezimbazo eziqondile). I-antenna ngayinye inezici zayo zokukhomba – indiza yesibuko se-antenna egxile ngqo iqondiswe ku-satellite ngesikhathi sokulungisa ngokuhambisana nedatha yokuphakama. I-antenna ye-offset inepharamitha eyengeziwe – “i-angle ye-offset”, inani layo lingatholakala emibhalweni yothi.
Lapho usetha i-antenna ye-offset, indawo edingekayo yendiza yesibuko ibalwa ngefomula – ƛp = ƛm – ƛs. Lapho u-ƛp iyindawo edingekayo yesibuko se-antenna uma kuqhathaniswa nendawo evundlile, ƛm i-engeli yokuphakama ebalwa ngendlela yesofthiwe, ƛs i-engeli ye-offset ecaciswe kuphasiphothi yothi. Kwenzeka ukuthi ngemva kokubala, inani litholwa ngophawu lokususa, okusho ukuthi isibuko se-antenna kufanele sitshekiswe phansi ngenani le-engeli etholiwe.
I-azimuth kanye ne-engeli yokuphakama yesitsha sesathelayithi ingabalwa ngaphandle kokubala – ngokusebenzisa amafomula:
“Sesha” isathelayithi
Ukukhomba okuqondile kwe-antenna kusathelayithi kungahlukaniswa izigaba ezimbili. Esigabeni sokuqala, ukulungiswa “okubi” kwenziwa, okwesibili sekuvele kuphelile. Ukushuna okumahhadla kubhekisela ekukhombeni i-antenna kusathelayithi ku-azimuth kanye nokuphakama. Ukwenza lokhu, isibuko se-antenna siphakanyiswa yi-engeli yokuphakama ebaliwe (kucatshangelwa i-engeli ye-offset ye-antenna ngokwayo). Kulesi sigaba, i-goniometer exhunywe endizeni ye-antenna izoba usizo.
Ukuqondisa kwe-azimuth kwenziwa kusetshenziswa ikhampasi. Kukhona futhi indlela yokukhomba “ngokusho kwelanga”, inikeza imiphumela emihle, kodwa ekusebenzeni abantu abambalwa abayisebenzisayo ngenxa yokusetshenziswa kwayo okulinganiselwe (i-cloudiness, akunakwenzeka ngaso sonke isikhathi ukubala indawo ngqo yelanga ngesikhathi esifanele. njll.). Ukulungiswa kokugcina kwenziwa ngokufaka imitha ekhethekile – “SatFinder” kugebe lekhebula phakathi kwesiguquli kanye nomamukeli wesathelayithi. Amamitha angaba ukudayela okulula kanye nedijithali eyinkimbinkimbi. Kunoma ikuphi, noma iyiphi yazo yenza umsebenzi wayo.
Ukuze ulungise kahle, khulula amabhawodi wezinti bese uwazungezisa kancane ku-azimuth, uzama ukungeqi isivinini sokuphenduka esiyidigri engu-1 ngomzuzwana. Ngemva kokuthwebula isignali, izindlela zokujika okuncane (kwesokunxele/kwesokudla) zidinga ukufeza izinga lesiginali eliphezulu futhi zilungise uthi. Uma isignali ivela, kodwa empeleni ingaphenduli ekuphendukeni kwesibuko noma ikhwalithi ingazinzile, kunconywa ukuthi uphambukise i-antenna ngamadigri angu-1-2 nge-eksisi eqondile ehlobene ne-engeli yokuphakama. Imiphumela emihle kakhulu ngesikhathi esifushane ngangokunokwenzeka ingatholwa kusetshenziswa i-spectrum analyzer njengemitha, kodwa le divayisi ibiza kakhulu futhi ukuthengwa kwayo ngenxa yekesi elilodwa noma amabili ayivelakancane lokushunwa kwe-antenna akwenzeki. Uma kunesidingo, ungasetha isitsha sesathelayithi ngaphandle kwanoma yimaphi amadivaysi. Ukwenza lokhu, isamukeli sesathelayithi kanye ne-TV (ikhompyutha ephathekayo enemojuli ye-TV) kubekwa eduze kwesitsha ngokwaso, futhi isignali eyamukelwe igadwa esikalini sohlelo lokusetha lomamukeli. Ngesikhathi esifanayo, yebo, akunakwenzeka ukufeza ikhwalithi ephezulu kakhulu, kodwa le ndlela ifaneleka kakhulu ukusetshenziswa ekhaya.
