Esimeni esiguqukayo njalo sezinto zikagesi zabathengi, i-antenna ye-TV ethobekile isalokhu iyisisekelo sokufinyelela ukusakazwa kwethelevishini okuphuma emoyeni kuya emoyeni. Naphezu kokwanda kwezinsizakalo zokusakaza, izibukeli eziningi zithembele kuma-antenna eziteshini zasendaweni, ezemidlalo ezibukhoma, nezindaba ngaphandle komthwalo wokubhalisa kwanyanga zonke. Lo mhlahlandlela udingida izici ezibucayi zezimpondo ze-TV, unikeza abafundi ukuqonda okujulile kokuthi bangathuthukisa kanjani ulwazi lwabo lokubuka ithelevishini.
Okuqukethwe:
- Ukuqonda izisekelo zezinti ze-TV
– Ukubaluleka frequency nokwamukela
- Indoor vs. Izinti zangaphandle: Ukwenza ukukhetha okufanele
– Amathiphu ukufakwa for reception elilungile
- Ukuxazulula izinkinga ezivamile ze-antenna
Ukuqonda okuyisisekelo kwezimpondo ze-TV
Ama-antenna e-TV athwebula amasignali asemoyeni asakazwa iziteshi zikamabonakude, okuvumela ababukeli ukuthi babukele okuqukethwe ngaphandle kwekhebula noma okubhaliselwe kwesathelayithi. Lawa ma-antenna afika ngezinhlobo nosayizi abahlukahlukene, ngayinye yakhelwe ukuthola izinhlobo ezithile zamasiginali. Ukuqonda imigomo eyisisekelo yokuthi ama-antenna asebenza kanjani kubalulekile ekukhetheni efanele izidingo zakho. Izinto ezifana namandla esignali yokusakaza endaweni yakini, ibanga ukusuka kumbhoshongo oseduze wokusakaza, kanye nezithiyo ezingaba khona kungaba nomthelela omkhulu kwikhwalithi yokwamukela kwakho.
Ukubaluleka kokuvama nokwamukela
Ukusakaza kukamabonakude kusebenza kumabhendi amabili amafrikhwensi amakhulu: i-VHF (Imvamisa Ephakeme Kakhulu) kanye ne-UHF (Ultra High Frequency). Ibhendi ngayinye iphethe amashaneli ahlukene futhi inezici ezihlukile zokwamukela. Amasiginali e-VHF, ngokwesibonelo, athambekele kakhulu ekuphazamisekeni kodwa angahamba amabanga amade. Amasiginali we-UHF, ngakolunye uhlangothi, ahlinzeka ngekhwalithi engcono kodwa abe nobubanzi obufushane. Ukwazi ukuthi imaphi amashaneli atholakala endaweni yangakini kanye namaza ahambisanayo kusiza ekukhetheni uthi olungaluthwebula kahle.
Indoor vs. Izinti zangaphandle: Ukwenza ukukhetha okufanele
Isinqumo phakathi kwe-antenna yasendlini nengaphandle sincike ezintweni ezimbalwa, okuhlanganisa ukuba seduze kwakho nemibhoshongo yokusakaza kanye nemingcele ebonakalayo phakathi kwekhaya lakho nale mibhoshongo. Ama-antenna asendlini afaneleka futhi kulula ukuwamisa kodwa angase anganikezeli ngokwamukela okungcono kakhulu uma ukude nemithombo yokusakaza noma uzungezwe izakhiwo ezinde noma izihlahla. Ama-antenna angaphandle, ngenkathi edinga ukufakwa okuyinkimbinkimbi, angathwebula uhla olubanzi lwamasiginali futhi anikeze ukwamukelwa okuphezulu ezimeni eziyinselele.
Amathiphu wokufaka wokwamukela kahle
Ukufakwa ngendlela efanele kubalulekile ekukhuliseni ukusebenza kwe-antenna ye-TV yakho. Kuma-antenna asendlini, ukubeka uthi eduze kwefasitela futhi kude nezinto zikagesi kunganciphisa ukuphazamiseka. Ama-antenna angaphandle kufanele afakwe phezulu ngangokunokwenzeka, kahle ophahleni, ukugwema izithiyo. Kubalulekile futhi ukuhlola umumo we-antenna, njengoba ukulungisa isiqondiso sayo kungathuthukisa kakhulu amandla esignali nekhwalithi.
Ukuxazulula izinkinga ezivamile ze-antenna
Ngisho noma i-antenna efanele ifakwe kahle, izibukeli zingase zihlangabezane nezinkinga zokwamukela. Izinkinga ezijwayelekile zifaka i-pixelation, ukuphuma kwesignali, noma iziteshi ezingekho. Lezi zinkinga ngokuvamile zingaxazululwa ngokuskena kabusha amashaneli ku-TV yakho, ukulungisa ukubekwa kwe-antenna noma indlela eya ngakhona, noma ukwengeza i-amplifier ukuze kuthuthukiswe amandla esignali. Ukuqonda lezi zindlela zokuxazulula izinkinga kuqinisekisa ukuthi ukuphazamiseka okuncane akukuphazamisi ukubuka kwakho.
Isiphetho:
Ukukhetha nokusetha uthi lwe-TV olufanele kungathuthukisa kakhulu umuzwa wakho wokubuka ithelevishini, kunikeze ukufinyelela ezinhlobonhlobo zamashaneli angena emoyeni. Ngokuqonda izisekelo zendlela ama-antenna asebenza ngayo, ucabangela izidingo ezithile zendawo yakho, nokulandela izinqubo ezingcono kakhulu zokufakwa nokunakekelwa, ungajabulela ukwamukela okucacile, okuthembekile futhi usebenzise ngokugcwele isistimu yakho yokuzijabulisa yasekhaya.
