Outdoor Antenna TV: izinhlobo, incazelo umhlabeleli

Naphezu connectedness okwandile sabantu ezweni lethu, nengxenye omuhle Bakwethu uthanda ukuchitha isikhathi sabo mahhala ku esibukweni blue TV. Umehluko phakathi owakhileyo ezisemadolobheni nezisemakhaya ngokuya TV yezokusakaza kubaluleke kakhulu. Uma kuqala ngokuvamile lisetshenziswa kumasevisi TV ngokusebenzisa imigqa yaqashiswa (cable TV), owesibili kunzima ukwenza ngaphandle-antenna yangaphandle.

Zama ukuthola indlela ukukhetha antenna ongaphandle TV ngesikhathi ekotishi noma izwe nendlu, iziphi izinhlobo amadivaysi zingatholakala ku ukudayiswa, futhi selisho uhlu encane ethandwa kakhulu futhi babemhlonipha abanikazi amamodeli.

izinhlobo antenna

Ukuze uqale, thina isho izinhlobo ezinkulu lezi amadivaysi, okuyinto ehlukile kweyabantu nomunye ngokuya ukusebenza, ukubukeka kanye nezinye izimfanelo ezibalulekile. iziphetho Final mayelana sekufanele awushiye sokuthenga kuwufanele ukwenza okusekelwe izidingo zakho siqu kanye geolocation ekhaya lakho.

antenna satellite

Kuyinto ethandwa kakhulu namuhla "ipuleti" akuxhomekile ukusondela ukuba umbhoshongo TV, ngoba ukusakazwa kusetshenziswa isiphuphutheki. Ngaphezu kwalokho, i-antenna satellite ongaphandle-signal amandla ngoba TV futhi akuphazamisi sezwe.

Ngisho version kakhulu okulula "amapuleti", ezifana ebalulekile offset noma ngqo ivumela ukuthatha ngokuphepha izithombe izinga okusezingeni. Lapha ungakwazi ukwengeza inani elikhulu abahlinzeka ngemisebenzi, futhi ngesikhathi esifanayo eziningi iziteshi.

Naphezu kokuba ezisobala satellite TV i-antenna yangaphandle kuya kwamanye amadivaysi, futhi kuba eyabo, ngoba ezinye yokuntula ezibucayi. Okokuqala - kungenye yezinkinga zamahhotela. Kube Akudingeki kube esichithwa uqobo "ipuleti", angaphansi kwendawo (isimo sezulu esibanda kakhulu, ukusondela zezimboni isignali wahlula futhi t. D.), ububanzi emikhulu nokuningi kudivayisi manufacturable liyadingeka, kanye ezibizayo. Okwesibili, uzodinga ukuthenga Isamukeli ekucubunguleni yezokusakaza futhi ezimweni ezimbi kakhulu le convector, ukuze uthole antenna ongaphandle TV ne-amplifier. Nokho, futhi, okwesithathu, ngokucacile ngeke engadingekile kokujwayelekile ezihlakaniphile ukusakaza kwe-TV, uyakwazi ukukhulula, futhi "inhlabamkhosi" isithombe izinga okusezingeni eliphezulu.

"Polish" antenna

Le yidivayisi elula kakhulu, linesizotha futhi ezishibhile, zazo kolwandle emhlabathini electronics emakethe. It has a isakhiwo ngehele nge amadevu futhi uphelele Cottages evamile. Nale antenna, ungakwazi ukubamba iziteshi zendawo idazini, kuhlanganise ORT futhi NTV. Ngaphezu kwalokho, ukuba iyatholakala aluminium izintambo, izintambo namathuluzi, ungakwazi kalula wenze lowo mkhaya uphinde uphile original ngezandla zakhe.

antenna Outdoor ngokuba TV plan onjalo ibekwe phezu kophahla isakhiwo, izinsika kanye nezinye izinkalo, enikeza emaphakathi iqhaza isiqondiso umbhoshongo. Lesi sakamuva kumele kube khona abangaphezu kuka-30 km kude nawe. Uma isimo sezwe wendawo buhlanjululwe izihlahla, izindunduma, izinqwaba noma nezinye izithiyo, adubule phansi isignali, ufake antenna ongaphandle TV yakho kufanele kwenziwe njengoba eliphezulu ngangokunokwenzeka. Eendabeni ezirareneko, ukuze usimamise ukusakaza futhi exclusion iningi ukuphazamiseka ukusiza amandla ochazayo.

"Polish" antenna inzuzo block

Amadivayisi anjalo kakade off the line umhlangano nge amplifier esakhelwe, zibizwa ngokuthi "asebenzayo". antenna Outdoor for TV we plan kakhulu wenabisa uhlu iziteshi ezitholakalayo TV futhi ezithuthukisa ukusakaza.

Umklamo kule yunithi siqukethe amabhlogo eziningana ehlukile, okuyinto ahlelwe ngendlela ethile ukukhulisa umbono we isignali. amplifier Yangaphakathi ikhulisa reception indawo 80 km, siqaphela ngisho ukusakaza ababuthakathaka (ngokuvamile ukulahlekelwa izinga). Njengoba esimweni sangaphambilini, ukwenza antenna ongaphandle TV ne-amplifier kungaba yezandla zabo. Into kuphela udinga ngaphezu izinto ngenhla - lena eliphezulu Converter. Faka kumadivayisi ezifana endaweni ephakeme kakhulu, isb ophahleni noma okuzenzela ikholomu / isigxobo.

Amadivayisi ngoba wave wokujikeleza (Yagi-Uda)

Antenna alesi sigaba abe phezulu ngokwanele ekungeyona eyakhe ukusebenza futhi ezihlangene. Zonke izingxenye ezinkulu apharathasi ziphephile ingalo abavamile. Ngaphezu kwalokho, lolu hlobo antenna uyakwazi ukusebenza amaqoqo ambalwa, okuyinto ebaluleke kakhulu emizaneni kude futhi nezingafinyeleleki, lapho kuphela umbhoshongo ubudala eseduze, yokwethula amaza non-standard.

antenna Digital

Amadivayisi anjalo libe izingxenye ezimbili - Sombhalo for digital signal processing kanye Uhlaka antenna efakwe ngaphandle. Umklamo we yokugcina silula, ngoba umthwalo esiyinhloko isignali reception nje ku Sombhalo. Digital ongaphandle antenna TV ephelele kulabo "abangane" ne ubuchwepheshe besimanje, abamesabi eziningi ongakhetha / ukuhlukahluka kwimenyu, futhi ondlu itholakala eduze komuzi. Amadivayisi anjalo zilungiswa ukwamukela kuphela isignali main futhi uzibe ukuphazamiseka kubonakala kahle.

izinhlobo antenna

ezimbili kuphela izinhlobo antenna lingachazwa - yekwentiwa kanye asebenzayo. Samuntu yokuqala isikisela ahlukene / Converter zangaphandle, owesibili - ne amplifier ehlangene. On izinga isignali reception akuzona kakhulu ezahlukene, kodwa ukuqina - kakhulu.

Imishini esebenzayo efakwe "njengoba injalo", okusho ngaphandle noma yikuphi ukuvikelwa okungeziwe, liyokuma esingaphezudlwana konyaka, ngenxa yesimo sezulu esibi futhi ukugqwala esakhelwe Converter iqala lwehluleke. onobuhle Passive ihambisane-amplifier zangaphandle, okungase elise ekhaya noma endaweni ethile ekamelweni elisophahleni, ngakho impilo inkonzo antenna enjalo isikhathi eside.

antenna Iningi ongaphandle TV

Ngo-electronics yasekhaya emakethe, ungathola inombolo enkulu zonke izinhlobo abamukelayo izinhlobo ezahlukene kanye izinhlobo, lapho uchungechunge ngamunye noma imodeli bazivumelanisa nezimo ezithile isignali reception. Ngakho-ke, ukuveza noma locingo njengoba best nzima kakhulu, umuntu kufanele acabangele izici ngabanye abaningi (geolocation endlini TV eseduze umbhoshongo, izinga isignali sezwe nokunye. N.). Nokho, ukwenza uhlu abakhiqizi best of antenna, okuyinto okuye kwenziwa kuye kwabonisa ngokwabo emehlweni abathengi okhuthele, kuyinto ehluke ngempela.

Antenna "Delta"

Antenna wale nkampani babenezikhundla udumo enviable phakathi abathengi yasekhaya, ikakhulukazi njengoba uhla inkampani wehlukile kakhulu. On emashalofini ungathola kokubili onobuhle esinda ebhekiwe ukuthi zenzelwe kuphela VHF futhi UHF, futhi injongo amadivayisi jikelele.

Ngaphezu kwalokho, iningi lama-antenna kusukela "delta" ongasebenza nge kusiginali yedijithali. Uxhumano futhi ukufakwa amadivaysi kuqhathaniswa ilula ngokwanele ukuthi ufaka ikhebula ku isixhumi ne-F-amplifier futhi silungise idivaysi iphuzu esiphezulu kungenzeka yendlu. Antenna ukwenza kahle lokumamukela futhi signal processing, ngisho at amabanga amade uma liya kusukela embhoshongweni ekhaya ithelevishini.

antenna Lokus

I okunezinhlobonhlobo inkampani kukhona njengelisebenzayo (nge Converter ehlangene) kanye imodeli yokwenziwa (nge-amplifier zangaphandle). abathengi Domestic ikakhulukazi edonsela Inqubomgomo intengo kanye brand ezinhle kakhulu imikhiqizo izinga.

Antenna design silula futhi ayidingi ukufakwa amanye amathuluzi athile noma ukuqeqeshwa. Amadivayisi enzelwe ukusebenza ngesikhathi esisodwa TV ezimbili noma ezintathu, ngakho bamba ngisho Villas ezinkulu.

Antenna "inhlendla"

Omunye umholi wahlonishwa ukukhiqizwa eliphezulu antenna emakethe yasekhaya. Amanani ziyahlukahluka, nakuba yeningi, kodwa kumadivayisi inkampani BakaJehova baziwa "omnivorous." Cishe zonke imodeli "inhlendla" uphelele ezindaweni isignali reception lingaqinisekile.

Futhi, ezinhle isignali selectivity antenna lokhu uphawu kakhulu aqede ukuphazamiseka esikrinini TV. Omunye bokwenza ezibucayi "inhlendla" imikhiqizo - kungcono fastidiousness ukuba imitha yamaza, ngakho lapho esebenza amadala TV umbhoshongo kungaba nezinkinga.

antenna GoldMaster

Naphezu ezingaphezu kuka amanani ezingabizi imikhiqizo, amadivaysi wale nkampani abangela isiyaluyalu lokumamukela ezinhle kakhulu ezindaweni izinga abesabekayo isignali. Kususelwa impendulo yomsebenzisi, antenna brand GoldMaster ukubhekana kahle nesimo umsebenzi, ngisho ezindaweni ezisemaphandleni emaphandleni: isithombe esikrinini ngaphandle "iqhwa", isithombe ayiyiphansi noma iphazanyiswe amasignali engumakhelwane.

Ngaphezu kwalokho, amadivaysi bubekezelelwa kahle cishe kunoma iyiphi sezulu, kungaba imvula, iqhwa noma enkulu kwesivunguvungu. Phonsa in ngamanani aphansi imikhiqizo ukuthola okungcono kakhulu iholidi inketho lukamakhalekhukhwini.
