Kwimeko ehlala iguquguquka yezixhobo ze-elektroniki zabathengi, i-eriyali yeTV ethobekileyo ihlala isisiseko sokufikelela kumabonwakude asimahla ukuya emoyeni. Ngaphandle kokwanda kweenkonzo zokusasaza, ababukeli abaninzi baxhomekeke kwii-eriyali zamajelo asekhaya, imidlalo ephilayo, kunye neendaba ngaphandle komthwalo wokubhaliselwa kwenyanga. Esi sikhokelo sijonga imiba ebalulekileyo yee-eriyali zeTV, sinika abafundi ukuqonda okunzulu malunga nendlela yokwandisa amava abo okubukela umabonakude.

Ukuqonda iziseko ze-eriyali zeTV
Ii-eriyali zikamabonwakude zibamba imiqondiso esemoyeni esasazwa zizikhululo zikamabonwakude, zivumela ababukeli ukuba babukele umxholo ngaphandle kwentambo okanye umrhumo wesathelayithi. Ezi eriyali ziza ngeemilo ezahlukeneyo kunye nobukhulu, nganye iyilelwe ukufumana iintlobo ezithile zemiqondiso. Ukuqonda imigaqo-siseko esemva kwindlela ezisebenza ngayo ii-eriyali kubalulekile ekukhetheni eyona ilungileyo kwiimfuno zakho. Izinto ezinje ngamandla omqondiso wosasazo kwindawo yakho, umgama osuka kwinqaba yosasazo ekufutshane, kunye nezithintelo ezinokubakho zinokuchaphazela kakhulu umgangatho wokwamkela kwakho.
Ukubaluleka kokuphindaphinda kunye nokwamkelwa
Usasazo lukamabonakude lusebenza kumaqela amabini aphambili: i-VHF (i-Frequency ephezulu kakhulu) kunye ne-UHF (i-Ultra High Frequency). Ibhendi nganye iphethe amajelo ahlukeneyo kwaye ineempawu zokwamkela okwahlukileyo. Iimpawu ze-VHF, umzekelo, ziqhelene ngakumbi nokuphazamiseka kodwa zinokuhamba imigama emide. Imiqondiso ye-UHF, kwelinye icala, ibonelela ngomgangatho ongcono kodwa inoluhlu olufutshane. Ukwazi ukuba ngawaphi na amajelo akhoyo kwindawo yakho kunye nee-frequencies ezihambelanayo kunceda ekukhetheni i-eriyali enokuthi ibambe ngokufanelekileyo.
Indoor vs. ii-eriyali zangaphandle: Ukwenza ukhetho olufanelekileyo
Isigqibo phakathi kwe-eriyali yangaphakathi nangaphandle sixhomekeke kwizinto ezininzi, kubandakanya ukusondela kwakho kwiinqaba zokusasaza kunye nemiqobo ebonakalayo phakathi kwekhaya lakho kunye nezi nqaba. Ii-eriyali zangaphakathi zilungile kwaye kulula ukuseta kodwa zisenokungaboneleli ngeyona ndlela yokwamkela ukuba ukude nemithombo yosasazo okanye ungqongwe zizakhiwo ezinde okanye imithi. Ii-eriyali zangaphandle, ngelixa zifuna ukufakela okuntsonkothileyo, zinokubamba uluhlu olubanzi lweempawu kwaye zinikeze ulwamkelo oluphezulu kwiimeko ezinzima.
Iingcebiso zokufakela ukwamkelwa ngokufanelekileyo
Ufakelo olululo lubalulekile ekwandiseni ukusebenza kwe-eriyali yeTV yakho. Kwii-eriyali zangaphakathi, ukubeka i-eriyali kufutshane nefestile kwaye kude nezixhobo zombane kunokunciphisa ukuphazamiseka. Ii-eriyali zangaphandle kufuneka zixhonywe phezulu kangangoko kunokwenzeka, ngokufanelekileyo eluphahleni, ukunqanda imiqobo. Kukwabalulekile ukuba uzame ukuqhelaniswa ne-eriyali, njengoko ukuhlengahlengisa isalathiso sayo kunokuphucula kakhulu amandla ophawu kunye nomgangatho.
Ukusombulula imiba ye-eriyali eqhelekileyo
Nokuba i-eriyali elungileyo ifakwe ngokufanelekileyo, ababukeli banokudibana neengxaki zolwamkelo ngamaxesha athile. Imiba eqhelekileyo ibandakanya ipixelation, ukuphuma komqondiso, okanye amajelo angekhoyo. Ezi ngxaki zihlala zisonjululwa ngokujonga kwakhona amajelo kwi-TV yakho, ukulungisa indawo ebekwe kuyo i-eriyali okanye isalathiso, okanye ukongeza iamplifier ukonyusa amandla ophawu. Ukuqonda ezi ndlela zokusombulula ingxaki kuqinisekisa ukuba iihiccups ezincinci aziphazamisi amava akho okujonga.
Isiphelo:
Ukukhetha kunye nokuseta i-eriyali ye-TV efanelekileyo kunokwandisa kakhulu amava akho okubukela umabonwakude, kunikeze ukufikelela kuluhlu olubanzi lwamajelo asimahla ukuya emoyeni. Ngokuqonda iziseko zendlela yokusebenza kwe-eriyali, ukuqwalasela iimfuno ezithile zendawo yakho, kunye nokulandela iindlela ezifanelekileyo zofakelo kunye nokugcinwa, unokonwabela ulwamkelo olucacileyo, oluthembekileyo kwaye wenze uninzi lwenkqubo yakho yokuzonwabisa yasekhaya.
