Indlela ukukhetha intambo eriyali

Nangona ubukhulu kamabonakude intanethi, izindlu ezininzi kukho enye okanye nomabonakude eziliqela. Abanye ubukele imiphantsi ezifunyenwe ne antenna eqhelekileyo, enye - kukho isitya satellite, kakuhle, ngoxa abanye kunandipha iingenelo inkqubela ngohlobo kamabonakude yi intambo. Kule meko ezimbini zokuqala, ugqithiso uphawu ukusuka kumthombo ukuya i-kamabonwakude zisetyenziselwa intambo TV eriyali. Kucacile ukuba, ukususela iimpawu zaso kuxhomekeke kakhulu kumgangatho imifanekiso ezikhutshiweyo. Kubonakala ngathi ukuze kube lula ukuba umlinganiselo yindlu ngoko nangoko, ukuya emarikeni okanye evenkileni uthenge intambo antenna? Noko ke, le ngxelo kuphela ngokuyinxenye yinyaniso. Into yokuba umntu esinqwenela ukuthenga ngentambo eriyali, abathengisi ziya kufundiswa iinketho eziliqela olu hlobo mveliso. ukhethe ukuba zeziphi na?

izisekelo senkolelo

Nawuphi Intambo antenna, njengokuba igama layo lixela, i ekwanti kancinane enye kwenye iingcingo conductive, legqunyiwe ngomaleko ubushushu eqhelekileyo. Ekubeni injongo yawo ukutshintshela kwi uphazamiso TV eyabangelwa kwi-eriyali, kucacile ukuba imali ekhoyo kunye ombane sakugcina. Ngenxa yoko, intambo eriyali uba umbexeshi emithanjeni omncinci. Uphawu unikwe ezineqondo eliphakamileyo, yaye ngenxa yokusebenza eqhelekileyo yonke le nkqubo kubaluleke kakhulu ukuba ixabiso bokuxhathisa lwangaphakathi lwe wesiphaluka kamabonakude, kwaye ngentambo eriyali zifana ncam (ezifane). Nangona kunjalo, inani umlinganiselo multimeter kufuneka ibe Ohm - loo nto ngamampunge. Intambo eriyali luphawulwa ukuxhathisa yomtshangatshangiso, yaye ixabiso layo libalwa yi indlela ekhethekileyo. Kuba yayo uphawu ixabiso TV 75 ohms. Ngoko ke kwisigqibo sokuba nayiphi imichiza "extra" abaqhubi kubangela umqondiso ezongezelelweyo ayaphela. Kwakhona qaphela ukuba kufuneka esinye ngaphezulu ingongoma ebalulekileyo: intambo dish satellite - hayi ezikhethekileyo, kodwa TV. Ngokukhetha ngayo, kufuneka balandele imigaqo ebesikunike ngezantsi.

intambo imihlobo kumabonakude

Ngokuqhelekileyo, iindawo ezinkulu ezithengisayo zinika ukusuka iintlobo ezi-3 ukuya kwisi-6 of cable TV. Umahluko obonakalayo lokuqala - iindleko. Maxa wambi kuba idlelo-mbini. Umntu ofuna ukukhetha intambo elungileyo unikwa umbuzo osemthethweni malunga nezizathu lo mahluko. Yaye ngokwenene kakhulu ebalulekileyo.

Xa uthenga kufuneka sinikele ingqalelo umgangatho usambathisa. Ibiyeyona ndlela ebiza bhetele ulula kakhulu, kangangokuba kumgca lase lesitalato, asikwazi aziyi kuqwalaselwa. Khangela Kulula kakhulu - batyedi intambo. Ukuba sibuya yokugquma, uthabatha into enje kunokuba kuphela isithintelo ngamandla kule mali.

On reception umgangatho liyachatshazelwa nesixhobo kumqhubi ziko. Core inokuba ngokupheleleyo okanye ubhedu ngensimbi Cuprum overmolded. Le ukhetho lokuqala ekhethwayo, ke, into eninzi kakhulu. Ngamanye amaxesha ungabona umbala ezingundoqo ensimbi - into tinning (tin ukutyabeka) isetyenziselwa ukhuselo evela igcwala.

Umaleko elandelayo ukuyigubungela umqhubi engundoqo kunye ubushushu bayo - ke screen. It is a umaleko alumuniyam eliqinileyo. Kokuba extruded okanye ejijekileyo. Ingaba kuyimfuneko ukunqanda uphazamiseko efanayo kule abaqhubi. Nangona kukho ulungiso intambo ngaphandle umaleko, phambi kwalo bubungqina engangqalanga umgangatho weemveliso.

Ngaphezu koko, umqhubi yesibini - a qhina. It iqulathe kweenwele zesinyithi ezicekethekileyo eziliqela, wambopha ngokukhethekileyo. Okukhona - ngcono. Ngaphezu koko, kubalulekile ukuba ubhedu (tin kuvunyelwe), kwaye hayi intsimbi.
