Indlela ukuxhuma TV kwamabili kuya kwelilodwa antenna: imisebenzi inqubo

Cishe wonke umndeni isilinganiso has a TV yesibili ekhishini, egumbini lokulala, futhi ngezinye izikhathi ephasishi. Ngakho-ke, i-eziningi umbuzo kanjani ukuxhuma namathelevishini amabili kuya ine-antenna eyodwa, kuba impela abukhali. Izindlela kungabi kuncane kakhulu, kodwa thina sizogxila izindlela ezilula kakhulu kodwa ngempumelelo.

Ngakho, sibheka indlela ukuxhuma namathelevishini amabili kuya ine-antenna eyodwa, okuyinto amathuluzi adingekayo, futhi thina isho izigaba eziyinhloko yale nqubo.

Yini edingekayo

Ngo inqubo uxhumano sidinga imininingwane embalwa. Izinsimbi zomculo uyokwenza njengokungathi impintshisi, ohlangothini bezihlahla kanye abavamile ekhishini ummese.

Okokuqala, kudingeka idabula TV noma idabula. Le divayisi uyakwazi ukuhlukanisa isiginali kusuka antenna izenze ukusakazwa amaningi (kithi - amabili). Okungukuthi, ngakolunye uhlangothi kukhona emnyango, futhi ngakolunye - okukhiphayo amaningi ukuxhuma kwi-umamukeli.

Ngokulandelayo, sidinga nezixhumi ezinhlanu ehambelana ububanzi we okukhiphayo we idabula, futhi-plug ezimbili adaptha. Antenna ikhebula khetha, ngokubona kwayo, kodwa kungcono ukuyeka ngisho izinketho ezibizayo, kodwa kungase kutholakale - RG-6 noma i-RK-75 yasekhaya.

Kubalulekile ucabangela ukuthi uma uthenga idabula liyadingeka ukuze ucacise isibalo okukhiphayo. Ngokwesibonelo, ezintathu-indlela imodeli yakhelwe ukuxhumana TV ezintathu, kodwa hhayi ezimbili. Uma ngasizathu simbe kuyoba esandleni ngesikhathi idabula abamukelayo ezintathu, okukhiphayo engadingekile kungenziwa ime Resistor ekhethekile ballistic nge ukumelana 75 ohms. Qiniseka ukuthi uqaphele ku iphuzu le ukunakekela okukhethekile ngaphambi ukuxhuma namathelevishini amabili kuya ine-antenna eyodwa.

Imisebenzi inqubo

Ngomqondo onabile, kakhulu inqubo uxhumano ilula, futhi uyakwazi ukusingatha yimuphi umsebenzisi, ngisho nalabo zizizwe umsakazo. Ngokucaca, thina uhlukanise yonke le nqubo ibe izigaba ehlukile.

Ukukhetha idabula TV

Okokuqala udinga ukuthenga idabula. On emashalofini ungathola anhlobonhlobo onobuhle ezivela abakhiqizi ezahlukene. Isebenza umthetho elula - the ezibizayo ngcono. Kodwa kukhona esinye iphuzu elibalulekile kufanele ukuba unake ngaphambi ukuxhuma namathelevishini amabili kuya ine-antenna eyodwa. Sikhuluma Ukudla. Uma une amakhono ukusebenza ngensimbi nokunamathisela ngomthofu, kungcono makudle onobuhle nge nokunamathisela ngomthofu. splitters okunjalo, futhi ngokukhethekile kwakwakhe okunokwethenjelwa njalo, zihilela zincane isignali ukulahlekelwa kanye kulondolozwe izinga.

Kuleso simo, uma insimbi nokunamathisela ngomthofu kuwe - uyinto engaqondakali, ungathatha i idabula abajwayelekile, kodwa futhi esekelwe ikhebula uhlobo ekhona - noma okuphambene nalokho. Lowo elilungile kakhulu kungenziwa ngokuthi idabula kwezixhumanisi indinganiso izintambo coaxial (ikhebula antenna uhlobo RG-6 / RK-75). Uma unquma on the idabula, udinga ukukhetha nezixhumi ezifanele. Ethandwa kakhulu kwaba elula, ethembekile futhi kulula ukufaka F-interface (adaptha-Ukugoqa).

Futhi, ukunaka ngokukhethekile kufanele kukhokhelwe indawo idabula. Inketho engcono kubhekwa ibanga okungenani zilingana kusukela idabula kuya TV ezimbili. Kubalulekile ukuthi ikhebuli antenna lalingelakulinganiswa elula futhi twist, ukuthi, ungazami yokwelula ke ngenxa yokuntuleka kwe-footage, noma, Ngakolunye uhlangothi, yokulisonta. Oku-ukubala ibanga ukusuka idabula TV ngiqede ngokweqile.

ikhebula ukulungiselela

Ikhebula kumelwe inqunywe ukuze kufinyelelwe ngokukhululekile ukuze idabula. Njengomthetho, kanye ucezu wire wanquma ipulaki ubudala. Khona-ke kudingeka usike ikhebula ukufakwa F-isixhumi.

Okokuqala thina onqenqemeni ahlanzekile, isb ukusika ukwaluka wrapper (ye-oda of 15 mm ukusuka emaphethelweni) kanye onqenqemeni egoba. Nangokuvikela "jacket" on the ikhebula kufanele kube isenzo kancane, futhi ekupheleni kwentambo ukushiya engengaphansi kwengu-4-7 mm. Zonke ikhebula inqubo belungiselela i-plug-adaptha engenziwa usebenzisa ummese ekhishini futhi ohlangothini bezihlahla.

Izici nezinqubo

Kubalulekile futhi ukwazi ukuthi isihlangu ikhebula kuyinto nganoma iyiphi indlela akufanele uthinte umqhubi emaphakathi. Leli phutha igcwele esinqunyiwe noma ephelele isignali ukulahlekelwa. Izinkinga ezinjalo ngokuvamile engavela izintambo brand SAT 703V futhi DG-113, lapho ungqimba ngamunye mncane kakhulu.

Okulandelayo, babuthane phezu ikhebula F-isixhumi. Igama elithi "ukukopela" kwaba ngenxa yokufaka ethize lapho ipulaki omane screwed ungene wire. Inqubo efanayo kumele kwenziwe kuwo wonke izintambo - futhi ekugcineni wathola nezixhumi ezinhlanu: owodwa kusukela antenna, ngoba imiphumela ezimbili nokokufaka ezimbili.

uxhumano

I-oda efanele izintambo yokuxhuma idabula. Hhayi ubaluleke kakhulu kangakanani ukoma F-uhlobo isixhumi, ngoba kungaholela ekulahlekelweni imicu eyinhloko adaptha. Abantu abaningi ushiye idabula njengoba injalo, ukuthi, ensimbi alenga endaweni ethile phezu baseboard noma ngaphansi nightstand. Ochwepheshe batusa ukuthi ukulungisa idabula ukuze ugweme zokugwema ukuphuka nokulahlekelwa cores. Uma izingane zikhona ke into edingekayo ukuze lelisu, plus konke kuyasiza ukufihla idabula ngaphansi kwanoma iyiphi iphaneli yokusebenza.

Uma kwenziwe ngendlela efanele, kokubili ama-TV, isithombe kumele kube sobala futhi ngaphandle kokuphazanyiswa. Uma kungenjalo, ungase uthole "iqhwa" ethize ngenxa ukulahlekelwa yingxenye isignali noma ukungabi khona izithombe.

Satellite TV

Isikhathi esining impela kwenzeka ukuthi ngisho nangemva izinga ukufakwa abanekhono idabula isithombe iye yawohloka. Lokhu kwenzeka uma ukuxhuma namathelevishini ezimbili kuya satellite dish olulodwa. kuphakama inkinga esuka iqiniso lokuthi idabula ngabe yikuphi ithatha ingxenye isignali.

Omunye ikhambi lale nkinga - kuba ukuthengwa idabula nge esakhelwe isignali amplifier. amadivaysi ezinjalo kakhulu ezibizayo, kodwa ngesikhathi esifanayo zingabantu kuphumelela kangcono kunokuthi nozakwabo abavamile.

Kuyadingeka ukucacisa ukuthi zonke splitters nge yokukhulisa umsindo okuhlangene babe uzuza ezahlukene. Kwezinye izimo, isignali is ngokucacile anda engenamsebenzi njengokwenza ababuthakathaka. Ngaphezu kwalokho, lokho kungase kubangele ukuhlanekezela okwengeziwe yesithombe. Nale ehilelekile is kaningi ebhekana nabantu nalabo abafuna ukuxhuma namathelevishini amabili kuya ine-antenna eyodwa "Tricolor" noma "Rainbow TV". Lapha udinga usizo uchwepheshe inkonzo umhlinzeki wakho, kungaba lapho ulinganise isignali futhi anikeze iseluleko kukhethwa eyodwa noma enye yezinto idabula nge izibalo ukhonkolo.

Antenna ne amplifier

Uma sikhuluma i "sula" abavamile antenna, ngcono isignali Ungaxhuma-amplifier ne kwamandla ukuthi ngokuphawulekayo lenyuka izinga isithombe.

Ukuze wenze lokhu, lapho esibona siwubonisa ajwayelekile wenze izinguquko ezithile. Kuyadingeka ukuba asuse F-isixhumi kusukela emnyango idabula ke isikhala baphume ukufaka i-plug nge amandla supply eliza "Polish" antenna. Ngemva kwalokho, ngo-adaptha okokufaka kufanele ukukhwezwa nge jack antenna ( "umama") bese uxhuma isixhumi ukuze amplifier.

Le nqubo kuzokhuphula inzuzo, lapho, ngokungafani TV satellite, seqiwe akubalulekile kangako, ngakho izinkinga nge ngokweqile isiginali kufanele kube.

Futhi, kuyasiza ukwazi ukuthi ithelevishini ngayinye elandelayo kunciphisa kakhulu izinga reception. Ngakho-ke, ukuze kubukwe okunethezekile izintandokazi zakho zemibukiso ye-TV kungcono hhayi splurge futhi uthenge i-antenna ezengeziwe esikhundleni "magic" ne idabula. Le tip kubalulekile ikakhulukazi uma umbhoshongo TV akhiwe kude kakhulu kusukela umamukeli.
