I-antenna ihlala ingcono kakhulu uma iqhathaniswa nethelevishini yekhebula. Uma unama-TV amaningi endlini yakho, njengoba abantu abaningi benawo, futhi awukwazi ukunamathisela uthi oluhlukile nge-TV ngayinye ukuze kube nendlela ongathuthukisa ngayo ukuxhumana kwamathelevishini amaningana nge-antenna efanayo yangaphandle. .

Ukusebenzisa i-antenna splitter kubonakala kuyindlela elula kakhulu yokusungula uxhumano lwama-TV amaningi ngothi olulodwa. Kodwa ukunciphisa ikhebula elihlangene elilodwa elisuka othini langaphandle liye ku-TV yakho akuwona umsebenzi oyisisekelo. Futhi, uma usebenzisa i-coax yekhwalithi ephansi, kukhona ukulahlekelwa amasiginali ngendlela njengoba intambo ye-coaxial yehla endlini yakho.

Inqubo ye-stepwise yokusungula uxhumano

Ukukhetha intambo ye-coaxial

Ukukhetha uhlobo olulungile lwentambo ye-coaxial kubalulekile ngenkathi usungula uxhumano lwama-TV amaningi ngothi olulodwa. Ngakho-ke uma ufuna ukukhetha ikhebula le-coaxial, kungcono ngaso sonke isikhathi ukuhamba nezintambo ezisekelwe ethusi njengoba ziqinisekisa ukuthi kukhona ukulahlekelwa kwesignali ephansi uma kuqhathaniswa nezinye izintambo.

Intambo yocingo isivele inikezwe nothi. Ungasebenzisa futhi leyo ntambo ukuze uthole uxhumano, kodwa ikhwalithi yesithombe ayithenjiswanga nayo. Ukusebenzisa intambo ye-coaxial efanele kungakusiza ukuthi uthole amasignali ekhwalithi enhle ngisho noma usebenzisa uthi olulodwa ukuxhuma ama-TV endlu yakho yonke.

Intambo yocingo isivele inikezwe nothi Ungasebenzisa futhi leyo ntambo ukuze uthole uxhumano, kodwa ikhwalithi yesithombe ayithenjiswanga nayo. Ukusebenzisa intambo ye-coaxial efanele kungakusiza ukuthi uthole amasignali ekhwalithi enhle ngisho noma usebenzisa uthi olulodwa ukuxhuma ama-TV endlu yakho yonke.

Ukukhetha uhlobo olufanele lwe-antenna

Ukukhethwa kwe-antenna yasendlini nengaphandle kuncike emithethweni naseziqondisweni zendawo yangakini. Uma uvunyelwe ukuthi ube ne-antenna yangaphandle, khona-ke kungcono ukuthi uthole i-antenna yangaphandle eneziqondiso eziningi ukuze usungule uxhumano endlini yakho yonke.

Kungenxa yesizathu sokuthi ama-antenna angaphandle avame ukufakwa ngaphezu komhlaba njengoba amasignali asatshalaliswa emkhathini, ngakho-ke kungcono ukuthi uthi lwakho lube khona esikhaleni ukuze lwamukele kangcono amasignali amabili.

Kodwa akusho ukuthi awukwazi ukuba ne-antenna yasendlini I-antenna yasendlini enamandla ingaba umthombo wokunikezwa kwesignali kuma-TV akho. Ungakwazi futhi ukunamathisela idigri eyodwa noma amabili ngothi olulodwa lwasendlini futhi uthole olunye uthi lwenye i-TV, ngokulandelana.

Manje sesimi ngomumo nge-antenna efanele nentambo ye-coaxial. Isinyathelo esilandelayo ukusungula uxhumano lwe-antenna nawo wonke ama-TV azungeze indlu yakho.

Ukufakwa kwe-antenna

Ake sithi ufaka uthi olungaphandle okufanele kucatshangelwe ukuma kwalo. Ngale njongo, ungasebenzisa ikhampasi ukuze uqondise i-antenna yakho ngasembhoshongweni wokudlulisela. Kuvame ukushiwo ukuthi ungabeka i-antenna yangaphandle enezikhombisi-ndlela eziningi kunoma iyiphi indawo kanye nendawo oyithandayo. Noma kunjalo, ngisho nezimpondo eziningi zangaphandle zisebenza kahle kakhulu uma uzibeke endaweni efanele yesiteshi sokudlulisa.

Njengoba i-antenna yakho ye-TV ifakiwe, udinga ukuskena ngesandla ku-TV yakho ukuze uhlole ukuthi mangaki amashaneli ongawafinyelela usuka ohlangothini oluthile lothi. Ukusebenzisa i-amplifier kusiza ekufinyeleleni iziteshi ze-TV ezengeziwe, kodwa kuyatuseka ukuthi uhlole isiteshi ngaphandle kokusebenzisa i-amplifier kuqala.

Ukukhetha uhlobo olufanele lwe-amplifier

I-antenna yasendlini ine-amplifier ekhona yokuthuthukisa amasignali; Nokho, nge-antenna yangaphandle, udinga i-amplifier ukuze uthuthukise ukusebenza kwayo. Ikakhulukazi kunezinhlobo ezimbili zama-amplifiers lezi zingama-pre-amplifiers kanye nezikhulisamandla zokusabalalisa.

Ama-pre-amplifiers axhunywe phakathi kwentambo ye-coaxial kanye nothi. Ifakelwa ukuthuthukisa amasignali abanjwe uthi ngaphambi kokuba yamukelwe yi-TV. Ama-amplifiers okusabalalisa asetshenziswa uma sixhuma amadivayisi amaningi ngothi olulodwa. Ithuthukisa amandla esignali ngenkathi ihlukanisa isignali ngokulinganayo kuwo wonke amadivayisi. Esimweni sethu, sizobe sisebenzisa i-amplifier yokusabalalisa.

Ukukhetha isihlukanisi sesignali

Ungasebenzisa isihlukanisi sezindlela ezimbili noma ezintathu esihlukanisayo sendlela engu-2 siyisihlukanisi esinokulinganisela futhi sivumela ukuxhumana kuzo zombili iziphetho. Inezimbobo ezimbili zokuxhuma izintambo zamakhoaxial ngayo. I-splitter yezindlela ezintathu ngokuvamile ayilingani futhi inezimbobo ezintathu zokunamathisela amakhebuli angama-coaxial. Ukulahlekelwa kwesignali kwenzeka kukho konke ukuxhumana kwe-splitter yezindlela ezintathu.

Isihlukanisi sezindlela ezintathu esilinganayo siyatholakala futhi, okubonisa ukuthi ukulahlekelwa kwesignali kuyehla kusukela kuchweba ngalinye lama-coaxial. Ngakho-ke, ukukhetha kwesihlukanisi ozosithenga kuncike enanini lokuxhuma ofuna ukulisungula usebenzisa isihlukanisi.

Isihlukanisi sihlukanisa isignali ngokulinganayo kuwo wonke ama-TV akho. Ngakho-ke uma usunamathisele ijezi ku-TV yakho, kuyancomeka ukuthi wenze ukuskena kwesiteshi mathupha ku-TV yakho ukuze uhlole ukuthi mangaki amasiginali awela phansi isihlukanisi sakho.

Lena yindlela ama-TV amaningi axhunywe ngayo othini olulodwa kusetshenziswa intambo ye-coaxial, i-antenna yangaphandle, i-amplifier, nezihlukanisi zesignali.

Inqubo esheshayo yokuxhuma ama-TV amaningi ngothi olulodwa

1. Thola i-coaxial splitter ehlanganisiwe nekhebula. Inamachweba amaningi okunamathiselwe kwezintambo ezimbalwa zentengiso ukuze kusungulwe uxhumano lwama-TV amaningi ngothi olulodwa lokwamukela.

2. Isinyathelo sesibili ukubekwa kothi lwakho. Faka i-antenna yangaphandle phezulu ngangokunokwenzeka ukuze uthole isignali engcono kakhulu.

3. Sebenzisa intambo eyodwa ye-coaxial eyehla isuka othini iye kuzihlukanisi bese uxhuma izintambo eziningi ezingamakhoaxial kudivayisi ngayinye ye-TV.

4. Ubude bentambo ye-coaxial kufanele bunyuswe, ngokufanayo kuye ngesidingo sakho sokuxhuma yonke i-TV ezungeze indlu yakho ngothi olulodwa.

5. Kutuswa ukuthi uvikele izintambo ze-coaxial ezindaweni eziphakeme ngangokunokwenzeka ukuze ungakhubeki phezu kwazo, noma intambo ye-coaxial ingabonakali ngendlela ye-loop, okuholela ekulahlekelweni kwesignali. Ikakhulukazi izintambo zamakhoaxial zigcinwa ziseduze nophahla ngangokunokwenzeka.

Ukushuna mathupha kufanele kwenziwe kumabonakude ngamunye ukusesha amashaneli e-TV adingekayo. Uma kufanele uxhume yonke i-TV esakhiweni sonke, kuyancomeka ukuthi usebenzise isihlukanisi esingaphezu kwesisodwa. Kodwa izinga lekhebula le-coaxial kufanele libe liphelele; uma kungenjalo, ikhwalithi yesithombe ayiqinisekisiwe kuwo wonke amasethi kamabonakude.

Iyiphi ingxenye ebaluleke kakhulu yokwenza ukuxhumana okuningi?

Ingxenye ebaluleke kakhulu ye-TV noxhumano lwe-antenna isihlukanisi sesignali. Njengoba intambo ye-coaxial esetshenziswa ekufakeni ibalulekile, isihlukanisi sesignali sibaluleke kakhulu. Kuyidivayisi esetshenziselwa ukusabalalisa amasiginali aphuma ku-antenna kuwo wonke amadivayisi akho ngosizo lwentambo ye-coaxial. Kuqukethe ukuphikiswa okuningi okuthuthukisa amasiginali avela kwiziphakeli zezinti kanye nokuya kuma-receptors e-TV.

Kunobubanzi obungashintshi befrikhwensi isihlukanisi sesiginali esivumela ukuthi sidlule kulo. Ngakho-ke, ngaphambi kokuthenga isihlukanisi sesignali, kufanele uhlole imvamisa yayo maqondana ne-antenna yakho. Isihlukanisi sesignali sakhiwe nge-aluminium siyenza iqine futhi ibe lula.

Isiphetho

Ngakho-ke ungakwazi ukuxhuma ama-TV amaningi ngothi olulodwa usebenzisa intambo ye-coaxial yekhwalithi enhle kanye nesihlukanisi sesignali. Kutuswa ukusebenzisa i-amplifier eqondisayo ukukhulisa amandla esignali avela ku-antenna.
