Zama ukufumana phandle ukukhetha indlela eriyali yangaphandle ukuya TV kwi cottage okanye kwilizwe indlu, yintoni iintlobo izixhobo zifumaneka yokuthengisa, kwaye lenza uluhlu encinane kakhulu zithandwa wathola ngokubhekiselele abanini imifanekiso.

iintlobo antenna

Okokuqala, siya ukuchaza iintlobo eziphambili zezi zixhobo, ezahlukileyo enye kwenye ngokwemiqathango ukusebenza, inkangeleko kunye nezinye iimpawu ezibalulekileyo. izigqibo zokugqibela malunga awushiye lokuthenga kubalulekile ukwenza ngokusekelwe kwiimfuno zakho kunye sendawo kwikhaya lakho.

antenna satellite

Kuyinto athandwa kakhulu kule mihla 'ipleyiti' akuxhomekekanga kufuphi nenqaba TV, kuba usasazo nge yesathelayithi. Ukongeza, i-eriyali satellite yangaphandle ixesha.Ngalo amandla ngenxa TV kwaye aluchaphazeli mmandla.

Nkqu uguqulelo kakhulu ezilula "amacwecwe", ezifana focal offset okanye ngqo ikuvumela ukuba ngokukhuselekileyo imifanekiso zomgangatho ophezulu. Apha ungadibanisa inani elikhulu zababoneleli-nkonzo, kwaye ngexesha elifanayo eninzi lamajelo.

Nangona iingenelo ezicacileyo ye TV satellite ye-eriyali ongaphandle nezinye izixhobo, kwaye kunjalo zabo, ngokuba neengxaki ezithile ezibalulekileyo.

Ukuba elimi lasekuhlaleni exutywe imithi, iindonga zokungqinga, iimfumba okanye neminye imiqobo, adubule phantsi umqondiso, faka i-eriyali ngaphandle TV yakho kufuneka njengok phezulu kangangoko kunokwenzeka. Kwiingxaki ezintsonkothileyo, ukuze uzinzise usasazo kunye nokungabandakanywa uninzi sokuphamazisa kunceda amandla ecacisiweyo.

"Polish" antenna inzuzo block

izixhobo ezinjalo sele off line ibandla kunye msindo eyakhelwe-ngaphakathi, kwaye zibizwa ngokuba "elisebenzayo". eriyali yangaphandle ukuba TV yesicwangciso iyavuleka kakhulu kuludwe lwamajelo ezikhoyo TV yaye kuphucula umgangatho zosasazo.

Kanye njengokuba njengakwimeko yangaphambili, ukuba enze eriyali ngaphandle kwi TV kunye ngombhobho kuba izandla zabo. Inye kuphela ufuna ukongeza izinto ngentla - oku luphawu converter ophezulu. Faka izixhobo ezifana kwindawo kunokwenzeka iphezulu, ngamanye ukuya kuphahla okanye umhlathi ekhaya / ipali.

Devices for iliza ohambahambayo (Yagi-Uda)

Eriyali kule klasi ikwazi ukusebenza eliphezulu foster ngokwaneleyo kwaye compact. Onke amacandelo ezinkulu izixhobo ukhuselekile ingalo omnye. Ukongeza, olu hlobo eriyali unako ukusebenza bands eziliqela, nto leyo ibaluleke kakhulu kwiilali ingafikeleleki ekude kwaye, apho nasenqabeni kuphela ubudala kufutshane, yasasazwa ezitsho non-esezantsi.

antenna Digital

izixhobo ezinjalo luqulathe izahlulo ezibini - Sombhalo for processing uphawu lwedijithali kunye isakhelo eriyali efakwe phandle. Uyilo yokugqibela ilula kakhulu, kuba uxanduva esingundoqo yokwamkela Oluphawu nje phezu esakhelwe. ogqibeleleyo kwabo "abahlobo" kunye ubugcisa bale mihla, Musa ukuwoyika iinketho ezininzi / umahluko kwi menu, kwaye zigazi ibekwe kufuphi nesixeko indlu Digital ngaphandle eriyali TV na. izixhobo ezinjalo ziyafakwa ukwamkela kuphela umqondiso ezingundoqo batyeshele uphazamiseko kubonakala kakuhle.

iintlobo antenna

N.). Kaloku, yenza uluhlu abenzi kakhulu-eriyali, ezithe ukuwuphumeza ngokwabo emehlweni bavakalelwa ukufunda, yinto yokwenene kakhulu.

Eriyali "Delta"

Eriyali yale nkampani ayephathwa kuthandwa umona phakathi abasebenzisi basekhaya, ingakumbi uluhlu imfuduka zahlukahlukene kakhulu. Ezishelfini uyakwazi ukufumana zombini imifuziselo ziwuphose ezijoliswe ukuba yenzelwe kuphela ukuba VHF kunye UHF, kunye nezixhobo nenjongo jikelele.

Ngaphezu koko, inkoliso eriyali ukusuka 'ogudle "unako ukusebenza kunye uphawu digital. Uqhagamshelwano kunye nofakelo yamacebo ndawo ilula ngokwaneleyo ukufaka intambo ukuya isinxibelelanisi kunye F-wokukhulisa kwaye ulungise ifowuni kwindawo liphezulu zendlu. Eriyali benza kakuhle ulwamkelo kunye uphawu processing, nokuba sikude kakhulu ukusuka kwinqaba kumabonwakude ekhaya.

antenna Lokus

Le neentlobontlobo kwenkampani kukho bamatasa (kunye converter ehlanganisiweyo) kunye nemodeli isixando (kunye ngombhobho wangaphandle). abathengi Domestic ingakumbi etsala nkqubo ixabiso lophawu entle kakhulu iimveliso esemgangathweni.

design eriyali ilula kakhulu kwaye ayifuni ufakelo kwezinye izixhobo okanye uqeqesho oluthile. Ezi zixhobo zenzelwe ukusebenza ngaxeshanye TV ababini okanye abathathu, ngoko ukungena kuse Villas ezinkulu.

Eriyali "Harpoon"

Enye owaziwa ekuvelisweni eriyali ezikumgangatho ophezulu kwimarike yasekhaya. Amaxabiso abafani, nangona wedemokhrasi, kodwa izixhobo zenkampani zaziwa ngokuba "zezitya konke." Phantse wonke imodeli "Harpoon" ugqibelele ukuba kwiindawo ekungaqinisekwanga uphawu ulwamkelo.
