Antenna Indoor-TV: izici, izinhlobo, ngebuhle nebubi

Okwamanje, cishe kuyo yonke imizi okungenani olulodwa neqoqo TV ezifuywayo noma amazwe. Ukuze unikeze isignali ukusakaza ithelevishini ke sidinga i-antenna. Kunezinhlobo eziningi amadivayisi kokuthola. Bahlukene ngokuvumelana uhlobo isignali eyamukelwe, ngesivumelwano, umumo kanye nosayizi. Ekhulunywe yethu namuhla elizoba Igumbi antenna ye-TV. Ngokuvamile, ama-receptor ezinjalo asetshenziswa iyunithi umile azikwazi ukufakwa noma izidingo zesikhashana. Ake sibone ukuthi iyini le antenna zasendlini namathelevishini, yini izici basuke ebonakala.

imikhiqizo enjalo kungaba iyehluka nohlobo isignali eyamukelwe (imitha futhi decimeter ububanzi), ukuma, ubukhulu, kungase kube yokwenziwa noma asebenzayo. antenna zasendlini namathelevishini ziphansi e izici ezibekiwe kumadivayisi angaphandle. Bangakwazi ukuletha izinga enhle isignali kuphela ebukhoneni umbhoshongo ithelevishini ngaphansi amafasitela yakho. Uma kungaqali ke inkinga iqala nge ukwamukelwa isignali. Isikhathi esining impela ungabona isithombe uma i-antenna angaphakathi elenga kwesihenqo metal noma aboshelwe kuso izingcezu wire, kodwa lezi zinyathelo kukhona esimweni ukuqinisekisa ikhwalithi enhle isignali. Namanje on screen sakho TV "iqhwa" ukugijima strip nokuningi.

Kodwa uma namanje nesithakazelo antenna zasendlini TV ke siqhubekela cabangela le mikhiqizo. Ukuma lezi amadivaysi incike wathola isignali band. Ngakho, abantu abaningi sebekholelwa isiswebhu antenna imitha ububanzi, abakubonisayo obuphelele ezimbili adjustable futhi ukuthambekela pin telescopic. A yesibili evamile uhlobo mangqamuzana ezinzwa decimeter - ezinhlanu noma ngaphezulu parallel aluminium babashayeli exhunywe ngokuvamile perpendicular uzimele.

Uma ungenayo okunye, futhi kumele basebenzise inguqulo zasendlini, ke kungcono ukuthenga umkhiqizo esinjalo, njengoba antenna esebenzayo ku-TV. antenna asebenzayo Indoor has a inzuzo ephakeme. Kodwa ungakhohlwa ukuthi ukudla ngakunye has yokusebenza yayo imvamisa ububanzi. Kukhona zasendlini antenna narrowband (owodwa isiteshi) broadband (multi-umzila). Ngamunye kudivayisi ethola kuvezwa MHz ububanzi. Ngokuvamile, antenna angaphakathi babe elinganiselwe imvamisa ububanzi. Okungukuthi, ezinye iziteshi kungenziwa wamisa ngekhwalithi ezinhle, abanye kuyoba kubi, kanti abanye abazi ukuphatha ukubamba. Lapha kumele kubhekwe uma kukhethwa lezi amadivaysi.

Ekuphetheni, uma udinga idivayisi eziphansi elula, kuyashesha futhi kulula ukuze usethe, inwebe noma nciphisa, wena-antenna angaphakathi ngempela efanelekayo TV. Izibuyekezo wale mikhiqizo ziyancipha yokuthi bona kukhona icwecwe futhi kulula ukuyisebenzisa, ephathekayo futhi asidingi nolwazi olukhethekile ukuze ulungisele ukusebenza.
