Lo mshini uphawu zikamabonakude ezahlukeneyo

Njengoko yokwenza ubonisa, umfanekiso kwi TV screen ayisoloko ukwanelisa umthengi ukuba umgangatho wabo. Kwiimeko ezinjalo ngokuqhelekileyo kunokusinceda uphawu kamabonwakude msindo - isixhobo ekuvumela ukuba ukunikezela inqanaba kakuhle komsebenzi receiver. Kuye sokulahla ukufaneleka kwayo ngexesha kuphuhliso okukhawulezileyo kobugcisa intambo. Into yokuba sixhobo inokusetyenziswa ngabasebenzisi njenge iinethiwekhi ehlangeneyo, yaye "intambo" ababhalisele.

Isicelo se lizwe

Lo mshini ye umqondiso kamabonakude ukunika encinane na isisombululo ogqibeleleyo abantu abahlala ngaphandle imizi. Inyaniso kukuba xa kungekho ubukho uqhagamshelwano kwinethiwekhi USB, amahlwempu ukwamkelwa uphawu eriyali, okanye nje phambi balwamkele ezininzi (TV), esi sixhobo buyafuneka. Oku kuyinyaniso ngokukodwa kwezo ndawo apho umphakamo wengxolo yendalo kuchaphazela umgangatho uphawu. Kufuneka kuqatshelwe ukuba kwiimeko ezinjalo, iingcali yaleza ukusebenzisa izixhobo ezifana ngenxa kumanqanaba ukungalungelelani kancinane okuluphawu uphawu igalelo. Phambi ukukhonza umabonwakude inqanaba lamandla uphawu ilungelelaniswe kwisiteshi ngasinye ngokwahlukeneyo.

yokukhulisa antenna

Kwimeko apho kwisamkeli signal ibekwe kude ukusuka kwisikhululo kumabonwakude, yaye ukuze ukubuyisela ngokulahlekelwa kwenzeka iintambo elide, oko kunilungele ukuba usebenzise yokukhulisa eriyali. Baya Kwakhona kudla ngokubizwa ngokuba "eriyali esebenzayo". Xa ukusetyenziswa, ukwanda umgangatho uphawu inokuba eqhelekileyo (wideband) okanye yahlula (UHF kunye VHF).

Kukhethwa ngombhobho

A abathengi umbuzo kakhulu ezinxulumene kwisixhobo efana kumabonwakude njengomqondiso msindo, "Indlela ukukhetha isixhobo esifanelekileyo:" Kuyimfuneko ukuba uyithathele ingqalelo ethile engundoqo iparameters. Eyokuqala yokusebenza yefrikhwensi. Into yokuba imijelo yokwamkela-eriyali ngokwayo yaye lo mshini kufuneka angqinelane. Omnye umba - inqanaba imveliso eliphezulu (ukuba icebo elungileyo, eli nani ngayo ayikho ngaphantsi kwe 100 dB / UV). Le caveat wesithathu kukuba inzuzo kufuneka libe omalunga kwisibonisi 40 dB. ukusetyenziswa kwamandla lohlobo ngesiqhelo ekwi asukela kwi-10 ukuya 60 Ma. Ukushwankathela kwisixhobo yokhetho, kufanele kuqatshelwe ukuba uphawu wokukhulisa umabonwakude kufuneka inzuzo enkulu kakhulu njalo kwi.

Yokukhulisa network intambo kunye neentlobo zabo

Ukufakela lo mshini nga kwenzeka kwiindawo ezahlukeneyo network kwababhalisele cable TV. Kulo mba, kukho iindlela ezininzi zezi zixhobo. ukhetho lwabo luxhomekeke kakhulu kwi indawo apho isixhobo siza kufakwa. Eyona eziphambili ze izixhobo - oku izindlu kunye yokukhulisa buti. Uhlobo lokuqala elula. Instruments leyo iphathwa, ngokuqhelekileyo sifakwe ezindlini, apho ufuna ukudibanisa nomabonakude ezininzi. yokukhulisa eziphangaleleyo, ngokusekelwe amagama abo, ibekwe kwiindlela USB. Kwiimeko ezininzi, ukuba ibekwe khona umzimba die-uphoswe etywiniweyo, ngoko ke kufuneka zibekwe nayiphi na inxalenye yothungelwano.

yokukhulisa satellite

Satellite TV isixhobo uphawu msindo isentsha noko. Inika umsebenzisi ithuba lokuba athathe zombini uMaSukude uphawu satellite. Xa esetyenziswe kumgama kude ukusuka eriyali kwenzeka ilahleko uphawu imbuyekezo kunye nokusasazwa yayo phakathi balwamkele ezininzi. yokukhulisa ezinjalo ungahlanganiswa okanye asebenze ngokwahlukeneyo.
