Isitya sesathelayithi sineenzuzo ezininzi ngaphezu kwezinye ii-eriyali ngokomgangatho wesandi esithunyelwayo kunye nomfanekiso. Ii-antenna zesathelayithi zahlulwe zibe yi-offset kunye ne-focus-focus (i-toroidal ku-subscriber satellite TV isetyenziswa ngokugqithisileyo), nganye ineenzuzo zayo kunye nokungalunganga. Eli nqaku lixelela malunga nokungafani, ukufakwa, ukusebenza kwezi ntlobo zamacwecwe. 
Ziziphi izitya zesathelayithi ezigxininisiweyo kunye nezijolise ngqo
Ii-antenna ezinebala lesibuko zihlulwe zibe yi-offset kunye nokugxila ngokuthe ngqo. Zombini zizitya zeparabolic, kodwa zinomohluko omkhulu. I-eriyali ye-offset ayinikwanga nkonzo kakhulu njengeyesibini. Kukho elinye igama lee-eriyali ezijolise ngqo-i-axisymmetric, kuba i-symmetry yazo yakhiwe malunga ne-axis enye. Isibuko sabo yi-paraboloid ye-revolution, imilo ijikelezileyo, isakhiwo sinegalelo kwi-coincidence ye-geometric axis kunye nombane. Kwi-axis efanayo kukho umguquli oqhotyoshelwe emacaleni omboniso kunye nokwakhiwa okukhethekileyo. 
Ukuba iisathelayithi zisondelelene kwenye, zibonwa nge-eriyali enye yokucima phambi kwezimbini. okanye abaguquleli abathathu. Iziguquli ezongezelelweyo ziqhotyoshelwe usebenzisa i-multifrids. Ngamanye amaxesha kunokwenzeka ukuseta iisathelayithi ezine. Qwalasela ukufakwa kweesathelayithi ezintathu. Ukufakela i-antenna , kuyimfuneko ukugqiba apho ii-satellites zikhoyo kwi-orbit. Kukho iinkqubo kunye nezixhobo ezimisela indawo, kodwa ungahamba ngeepleyiti ezikufutshane. 
Makhe sicinge i-orbit njengebhulorho yeconvex. Isiguquli sokuqala sifakwe kwisathelayithi ephakathi. Abaguquli becala babekwe ngokuhambelana nomfanekiso wesibuko, oko kukuthi, xa i-satellite ingasekhohlo nangaphezulu, umguquleli ubekwe ngasekunene nangaphantsi kweyona nto iphambili. Kubalulekile ukuba akukho miqobo endleleni ngendlela yemithi, izindlu ezide, njl. 
Ukufakela isitya sesatellite:
Ingqalelo! Kungcono ukufakela isakhiwo sonke sendlu uze uyilungise kwintaba yodonga.
I-converter ephakathi ifakwe kwi-bracket kwaye i-multifeeds ifakwe apho abaguquli becala bafakwe khona. Okokuqala, sibeka i-multifeed kwi-satellite ephezulu (ukuba ujongene ne-antenna, ikwicala lasekhohlo), i-fasteners ifakwe kwi-arc, idityaniswe kunye, i-fasteners ngendlela yendandatho kufuneka ibekwe kwelinye icala. yale bar, ityhubhu yesinyithi ibekwe apho, apho abaguquleli babanjwe khona. Isiguquli sibekwe kwi-multifeed. Ijikeleziswa malunga ne-100 degrees counterclockwise. Icandelo elinye lidla ngokulingana nezidanga ezintlanu. Uxhulumaniso lwemisonto – ngentsimbi yesithandathu. Iinkcukacha malunga nendlela yokuseta isitya sesathelayithi .
Ingqalelo! Xa ufaka iisathelayithi empuma yezantsi, umguquli kufuneka asongelwe kwicala elichaseneyo.
Sibeka abaguquleli besibini kunye neyesithathu ngendlela efanayo, ngamanani amancinci amadigri. Siyayiqinisa into esiyifakileyo. Kodwa kufuneka ukwenze ngaphandle kokunyaniseka, ukuze ungagqithisi kunye nomzuzu wokuzama. Silungiselela iziqwenga ezintathu zocingo, zihlambuluke kwaye zijike kwii-F-connectors, zihlambulule iziphelo zeengcingo kwii-casings zerubha ezikhuselayo, zibeke ezi ziqhagamshelo. Ukumisela isitya sesathelayithi:
- Ekuqaleni komsebenzi, kufuneka ufake i-satellite engundoqo. I-wire esuka kwi-converter ixhunywe kwi-input ye-1 ye-DiSEqC, ukusuka kwimveliso ye-DiSEqC yokutshintsha “i-Receiver” intambo ixhunyiwe kwigalelo lomamkeli (i-tuner) kwaye izixhobo zilungelelaniswa kwi-satellite esiyidingayo ngokukodwa. ityala. Ngenxa yale njongo, i-satellite receiver ifakwe kwi-TV kwiiparamitha ezifunekayo. Ifrikhwensi efunekayo isetwa ngesandla.
- Xa isignali ethi “LEVEL + QUALITY” ibonakala, kufuneka ugxininise kwi “QUALITY”. I-eriyali emi nkqo ijika ngasekunene nasekhohlo, xa kungekho mqondiso, ithambeka liyatshintsha. Xa umqondiso ubanjwe, sifezekisa ubuninzi. Emva koko siqala ukuSkena kwaye sibone ukuba sikhethe isathelayithi elungileyo.
- Siqinisa amantongomane okulungisa.
- Sidibanisa umguquli kwigalelo elifunwayo.
- Sidibanisa utshintsho lweDiSEqC.
- Kwimenyu yomamkeli wesathelayithi kwimowudi “yokufakelwa kwe-Antenna”, emva kokukhetha useto lokuguqula, sibeka i-DiSEqC ngokuvula iisathelayithi.
- Kwimo ye “Automatic setting”, siskena zonke iisathelayithi. Kufuneka sijonge ukuba zibanjiwe. Ukuba yonke into ilungile, ungabukela iTV.

Indlela yokufaka kunye nokuseta i-eriyali yokugxila ngokuthe ngqo
Umgaqo wofakelo uyafana, kodwa ukuseta kuhluke kancinane. Kuya kufuneka ufumane ukuphakama kunye ne-azimuth . Zingabalwa nge-calculator ye-intanethi. Funda imenyu, kukho icandelo “Inqanaba leSignali”, ebonisa iiparamitha ezibalulekileyo njenge “Nqanaba” kunye “noBulunga”.
Sihlanganisa i-eriyali. Ekuqaleni, iinkcukacha zibukeka ngolu hlobo:
Hlanganisa isibonisi. Ukuba kukho iiwasha, kufuneka zifakwe. Okukhona uyilo lomelele, ngcono, kufuneka usebenzise zonke ezi mpawu.
Sidibanisa ama-halves ngoncedo lwee-clamps kunye namantongomane.
Sihlanganisa isakhiwo senkxaso, qinisa umlenze nge-clamp.
Khetha iziqhoboshi. Emva koko, kufuneka ubeke iplate emlenzeni. Emva koko sonke isakhiwo sihlanganiswe, imilenze yayo efana nesigcawu. Umbhobho wangaphakathi kufuneka uphume malunga neemitha ezi-2. Isikali emilenzeni, ukuba kukho na, sibekwe kwindawo ethile kwi-38-40. Ukumisela isitya sesathelayithi esijolise ngqo kwiisathelayithi ezimbini iYamal (90) + ABC (75): https://youtu.be/4vixVSd_-RY
Iimpawu zokusebenza
Ngamanye amaxesha uphawu lwe-eriyali lubuthathaka kakhulu. Emva koko kufuneka ukhangele ukuba izibuko zeplate zikhubazekile ngendlela efana nesibhozo. Kubalulekile ukuba, ukuba ujonga i-reflector ihambelana nokuvula, imiphetho idibanisa ibe ngumgca omnye. Ukuba umamkeli akasebenzi kakuhle, kufuneka uthenge entsha. Ngamanye amaxesha kuyimfuneko ukuthenga isiguquli esinengxolo encinci. Ngamanye amaxesha ungathenga enye ikopi yebhetshi efanayo. Kubalulekile ukuba i-converter feed ihambelana ne-f / d yesibonisi.
Inyaniso enomdla. Kabini ngonyaka, ekwindla nasentwasahlobo equinoxes, ilanga livela ngokuhambelana nesathelayithi kunye ne-antenna yokufumana. Emva koko i-radiation yelanga ikwi-converter kunye nesignali yesathelayithi. Oku kuthoba umgangatho wophawu. Oku kungonakalisa izixhobo. Ngoko ke, kuyimfuneko ukubeka ikhadibhodi okanye i-polyethylene (opaque) isikrini phambi kwe-irradiator ngexesha.
Indlela yokukhetha ipleyiti kwimisebenzi yakho
I-eriyali nganye ilungile ngendlela yayo. I-Offset ikulungele ukuyifaka ecaleni kodonga. Abafumani khephu nemvula.
I-eriyali ye-parabolic ihlala inxulunyaniswa nesathelayithi [/ i-caption] Kodwa i-eriyali egxininise ngokuthe ngqo inendawo ye-electromagnetic kwi-feed, engenazo zonke iintlobo zokuphazamiseka, ezichaphazela umfanekiso ngendlela efanelekileyo. I-eriyali ye-Offset ayichatshazelwa kukuna kwemvula. Inombindi womxhuzulane osisigxina ezantsi. Kodwa i-eriyali egxile ngokuthe ngqo ihanjiswa kwinqanaba elikhulu. Ngoko ke, kubanikazi ukuba banqume ukuba yeyiphi i-antenna yokukhetha. Ukuya kumlinganiselo othile, kulungele ngakumbi ukusebenzisa i-offset plate, ngakumbi kuba ikhethwa kumakhaya abantu. Kodwa kwangaxeshanye, zombini i-eriyali zilungile ngendlela yazo. Ukuba bayanqwena, abaninzi bayakwazi ukukhusela i-eriyali egxile ngokuthe ngqo kwimvula. Kwanele ukukhusela i-irradiator yokuguqula ngokwayo nge-visor encinci kwibhotile yeplastiki. Ngoko ke, zombini iinguqu zamacwecwe zilungile ngendlela yazo, kuyimfuneko ukuqhubeka kwimeko yomntu.
Ukuqukumbela
Ngoko ke, izitya zesathelayithi, ezihlanjululwayo kunye nokugxila ngokuthe ngqo, zombini zibamba ngokugqibeleleyo iimpawu zesathelayithi, oku kufana kwazo. Ziyahluka kwisikhundla kwaye ngokuyinxenye kwimilo ye-paraboloid, oko kukuthi, i-antenna ye-offset ime kwi-angle echanekileyo, kwaye i-antenna yokugxila ngokuthe ngqo ibekwe ngokuthe tye. I-eriyali ye-offset ikhuselwe ngcono kuzo zonke iintlobo zemvula, kwaye ineziko elingcono lomxhuzulane, nangona isitya se-axisymmetric sinendawo engatshintshiyo ye-electromagnetic.
