TV antenna ukunikeza booster: yini ukukhetha?

Naphezu kweqiniso lokuthi ithelevishini manje limane lifakwe ngemuva ngemuva kwi-Inthanethi, abantu abaningi abakwazi ukucabanga ngokuphila kwabo ngaphandle kwalo. Sekuyisikhathi eside kufakwe ekuphileni kwethu kwansuku zonke. Abantu ezayo ukusebenza noma ukutadisha, bafuna unethezeke bese ubuka i-movie noma ulalele izindaba, bangabheki on the internet okuthile okuthakazelisayo. Yiqiniso, yonke into eyenzekayo emizini, kodwa ezindaweni zasemakhaya kungaba isignali enganamandla, okungadingi ukubukela i-TV.

Kulokhu-ke kubalulekile ukuba ukuxazulula le nkinga. Ngokuvamile, ufake i-satellite dish elikuvumela ukuba kahle siyixazulule. Ngeshwa, izindleko zayo futhi zaminyaka yonke kungaba ngempela okusezingeni eliphezulu ngawe. Yini ongayenza kulesi simo?

antenna

Namuhla, ungathola ezihlukahlukene izitsha ezahlukene ukuthi uzothola umphumela oyifunayo. Ungakhetha le divayisi kunoma iyiphi esikhwameni. Indlela ukukhetha-antenna kanye-amplifier ukunikeza?

I-antenna ngayine ungahle uthole isignali futhi wabasebenzisa njengezinceku digital. Lokhu uhla incike indawo umbhoshongo nezithiyo isignali. Uma indlu itholakala eduze umbhoshongo edluliselwe, isiginali zingafundwa ngisho evamile angenalutho ikhebula ithelevishini.

Yiqiniso, uma isayithi itholakala kungaphelele kude umbhoshongo, kubalulekile ukubheka ezinye izindlela. Indlela ukukhetha-antenna kanye-amplifier ukunikeza? Ake ukubhekana nale nkinga.

izinhlobo antenna

Ukukhetha antenna kwesokudla, uzobona ukuthi kukhona inombolo ngokwanele ezinkulu. Ahluke uhlobo indlela yokufaka kanye nekusita. Bonke asethwe ezimeni ezahlukahlukene. Ukuze ubone ukuthi onjani antenna kuyadingeka, kuyinto ukucacisa indawo kanye nohlobo isignali okhulisa.

antenna Indoor ne-amplifier ukunikeza

Antenna zixhunywe ngaphakathi egumbini, ngempela icwecwe futhi ingafakwa phezu flat. ngaleyo ndlela Lolu hlobo iyahluka kwenye izindlela saso. Ngeshwa, kufanele antenna angaphakathi efakwe kuphela edolobheni, eduze kwayo, noma uma i-cottage iseningizimu eduze umbhoshongo. Kwezinye izimo, ungatholi kangcono isignali reception. Kufanele kukhunjulwe ukuthi egumbini elilodwa njengoba isiginali kungaba namandla ngempela, futhi ulahleke yokudlulisa. Lokhu kwenzeka ngenxa izindonga noma nezinye izithiyo.

antenna Digital angayisekeli efakwe ngaphandle

antenna kwangaphandle zihlukile egumbini. Basuke efakwe emakhaya ukuthi zitholakala kude ngaphandle komuzi, lapho antenna ezivamile abakwazi ukubamba isiginali. Lolu hlobo kahle ukuthuthukisa reception. Yiqiniso, lezi antenna avame ukusetshenziswa, futhi ngakho Ziningi zilwane. Bahlukene ngokuvumelana uhlobo okhulisa kanye nendlela yokufaka. Hlobo luni antenna inzuzo ekhethiwe ukuba afakaze?

I-antenna ezivamile - kukhona yekwentiwa. Abanaso amamojulu ezenza okhulisa ezengeziwe. Yiqiniso, njengoba kade iphazanyiswe ukugula futhi kancane ukuthuthukisa izinga reception, kodwa ngokuvamile lokhu kunganele, uma Cottage kude imibhoshongo edluliselwe. Ngisho ifomu elula efana anezinye ezicini ezinhle. antenna Passive akusho ukwethula umsindo ku isiginali, esinikela eliphezulu sokudlala, yebo, uma kukhona amandla anele.

Eyesibili uhlobo - antenna asebenzayo. Ngobukhulu, ayefana kuya ukubukwa kwangaphambilini, kodwa kufanele busebenze ezengeziwe zandisa isignali. Zingase eziqukethwe antenna ngokwayo, ngaphandle-ke ngesimo-module ezengeziwe. Yiqiniso, kubalulekile ukuba amandla, okuyinto esabekwa Izitolo evamile.

Lesi sakamuva uhlobo - ohlangothini antenna, okuyinto azifane asebenzayo nomklamo walo. Umahluko omkhulu baqamekela yokuthi antenna ohlangothini makhulu futhi abe ezinye amamojulu. Ngakho, kuleli fomu nengaphakathi isethwe eside, futhi axhunyiwe nalokho izakhi ukuhlinzeka inzuzo. antenna kokuqondisa kuthiwa Lifanele for ezindaweni ezikude, zingabantu catch qualitatively ikhulise isignali. Ungase futhi sithathe amplifier ukuze antenna-TV kuleli zwe, ukuthuthukisa isignali.

Ngeshwa, ngisho nalapho ezinamandla Ukukhetha antenna bangathola isignali angahleliwe. Ngaphambi kokuthenga udinga ukucacisa ibanga kusukela embhoshongweni ukuze antenna futhi ukhethe okukhethwa kukho ezifanele kakhulu.

nzuzo

Indlela ukukhetha-antenna kanye-amplifier ukunikeza? Ngaphambi kubalulekile ukuqonda izici lobuchwepheshe zedivayisi. Ukuze ithelevishini antenna yangaphandle ukuze amplifier sokuwunikeza - inzuzo, okuyinto ulinganiswa dB. Le nkomba oyosibonisa kahle nendlela ongawuthola isibonakaliso sendawo ethile. Yiqiniso, kulapho inani, ngcono ikhwalithi reception, futhi ngenxa yalokho, ayanda intengo. Kunconywa ukuba akhethe antenna kanye isilinganiso engcono.

Ukukhetha uxhumano ikhebula

Ngemva kokukhetha efanelekayo ongaphandle antenna amplifier ngoba indlu, ungakwazi ukuqhubeka ukufaka futhi ulungiselele.

Ukuze hhayi ukuphazamisa wonke picture, udinga ukuthola ikhebula ezinhle, njengoba futhi sigcwalisa izinga isignali yokudlulisela. Noma ngabe uthenge isamukeli ezibizayo futhi antenna, yekhwalithi ephansi izintambo kungaba eziphukile. Yiqiniso, ngeke ukufanisa amba eqolo. Phawula futhi ugqinsi umqhubi emaphakathi okuyinto ukuba kunalokho obukhulu, futhi emgodleni yangaphandle. Ngaphambi oxhumanisa kuwufanele kokuhlola isici impedance, okuyinto kufanele azungeze 75 ohms.

Usezingeni models engcono

Indlela ukukhetha-antenna kanye-amplifier ukunikeza? Kunzima ukweluleka kungasilahlekisela okuthile, njengoba umuntu ngamunye kuyodingeka izimo ezahlukene ukuthola isiginali. endaweni abahlukahlukene kanye nebanga kusukela embhoshongweni repeater inquma antenna ezifanele. Usezingeni models esingcono kakhulu sokukusiza ngesikhalo ukhethe ezifanele.

1. "Delta" inkampani. Antenna wale nkampani kubhekwe ukuba izinga okusezingeni eliphezulu kakhulu, futhi uyohlala endaweni kuqala eziningi ihamba simo yethu akuyona ngaphandle. Lokhu kwenzeke sibonga anhlobonhlobo. Kuhlanganisa ahlukahlukene antenna ohlangothini kakhulu chweba imitha futhi decimeter amagagasi, namadivayisi broadband. Cishe wonke amamodeli singasetshenziswa kusiginali yedijithali. Ukuze uxhume, udinga ukufaka i-wire ku isixhumi, okuyinto has a F-isixhumi. Antenna inkampani "Delta" qualitatively ukwamukela uphawu nje efakiwe.
2. On endaweni yesibili Locus lukamakhalekhukhwini. Le nkampani ukuhlakulela onobuhle yekwentiwa kanye asebenzayo. Batfutfukisa kahle eliphezulu onobuhle, okuyizinto engabizi. Antenna ngokuvamile 3 kungenziwa exhunywe namathelevishini. Ukuze usungule model of Locus inkampani, akudingi amakhono akhethekile, yonke into ilula.
3. indawo Okwesithathu - inkampani "inhlendla". Kuyinto umkhiqizi ezinhle, enezela eliphezulu antenna kwanoma yiluphi uhlobo. Imikhiqizo eziyinhloko "inhlendla" kuyinto asesilinganisweni. Umenzi liyasiqinisekisa ukuthi wonke amamodeli bangathola isiginali kubi ngokwanele. Izifundo kanye amazwana asuka kubasebenzisi ibonisa ukuthi i-antenna kanye nezinjongo.
4. Khona-ke kukhona GoldMaster ngokuqinile. Antenna wale nkampani kule simo lokugcina onobuhle ethandwa kakhulu. Ziyakwazi eliphezulu kakhulu isignali izinga sitholwa. Nakuba i-TV, azikho izinkinga nge imifanekiso, ukuthi akukho ukuphazamiseka ezahlukene kanye amabhuleki. Futhi, isimo sezulu akuphazamisi izinga reception. Ingxenye best wukuthi nge izinga ezinhle le-antenna zingafundwa intengo imali.

Enye ukwenza isidlo kamabonakude wedwa. Ngakho ungenza choice esifanele endaweni yakho. Yiqiniso, kubalulekile ukuba ukusebenza kanzima, ngoba inkinga zazinzima kakhulu. Kuyi-Internet zikhona eziningi izincomo kanye ividiyo lapho ungenza ilungelo TV antenna ukunikeza booster.

izincomo

Uma ikhebula yakho coaxial, okuyinto ixhunywe antenna kanye TV waphula noma esidla izihluzu ezifuywayo, musa ngokushesha siqalise amasha. Ungaxhuma ezindaweni lonke. Ukuze wenze kanjalo, uhlanze amachopho solder othintana ezidingekayo.

Ukwamukela izinga isignali, kubalulekile ukuba banake ezahlukahlukene. Ngenxa ukufakwa ukuphakama, ephezulu voltage imigqa ukuthi sekuseduze ukuba ekhaya, uhlobo sezwe endaweni yangakini kanye impahla esasetshenziswa womshini ophahleni, ungakwazi ngcono noma zilulaza isignali. Kufanele kusetshenziswe ngesikhathi sokufaka, ungachithi isikhathi sakho udlale ngesikhathi.

isiphetho

TV-antenna kanye amplifier ngoba Cottages kumele akhethwe ngesisekelo endaweni yabo. Awukwazi ukukhetha okukhethwa kukho isebenziseka ngezindlela eziningi, udinga ukulinganisa zonke izici ukuze ukwazi ukuthola isibonisi izinga. Kunezinhlobo eziningana antenna ukuziqhathanisa nabanye kungafaneleka khona. Ngemva ekutholeni uhlobo lesifanele ungakwazi uqhubekele kukhethwa imodeli elifanele.
