Intambo yeCoaxial
Ukuzama ukufumana intambo ephezulu yokusebenza i-coaxial inokuhambisa ukuhanjiswa okuthembekileyo kunye nomqondiso oku kucacileyo? Emva koko jonga kwisiphelo se-RG174 esinentambo ephezulu engu-50ohm ye-Antenna. Le nto ikumgangatho ophakamileyo wenzelwe ukusetyenziswa kunye nee-eriyali, nto leyo eyenza ukuba ibe lukhetho olugqibeleleyo kwipropathi yakho okanye indawo yokusebenza.
Ukuqala, i-RG174 Ukusebenza okuPhezulu kwe-Coax kamabonakude wesathelayithi i-50ohm yenziwe nje phakathi kweentengiselwano ezininzi ezithe ngqo zokusetyenziswa ngokulula kwezinto ezilungileyo. Iselula yangaphandle yindawo ehambayo eyinyani umabonwakude okwinkqubo yekhompyuter wenziwa kwiPVC ehlala ixesha elide kwaye ethembekileyo enikezela ngokhuseleko olugqwesileyo ngokuchasene nokwenzakala, kunye neengxaki ezinkulu zokusingqongileyo. Oku kuthetha ukuba intambo kamabonakude inokusetyenziswa ngaphakathi nangaphandle kokusingqongileyo ngaphandle kokuphazamiseka.
Kwi-cable tv yenza malunga nenkcaso yi-50ohm enika isibonakaliso sokuba iphelele kwaye iyancipha ilahleko. Kuya kunceda ukuqinisekisa ukuba ugqithiso lwesalathisi luqinile kwaye luzinzile, kwaye lukhusela ezona nkqubo zininzi ziluncedo. Ukusebenzisa le ntambo ye-coax, ufumene amandla okulindela ukuba uya kufuna ulwaneliseko oluvela ekucaceni okungaphezulu okuqhelekileyo ukuthetha kwisandi sakho kunye nosasazo lwemuvi.
Enye injongo inkulu le coax cable kukuguquguquka kwayo. Umabonakude wesathelayithi kwipc unokuba ngumyinge omkhulu mhlawumbi ubuninzi boncedo lokusetyenziswa kwee-eriyali kunye nezixhobo zothumelo, ukwenza ukhetho olufanelekileyo lwezaphulelo ezifanelekileyo zekhaya okanye indawo yokusebenza. I-RG174 luxury Coax cable tv 50ohm iqinisekisa ukukwenzela umgangatho kunye nokuthembeka oyakudinga nokuba uyawuqala xa isiza kwiscreen sescreen sikamabonakude, unomathotholo, okanye ezinye izixhobo ezahlukeneyo.
I-RG174 High Effectiveness Coax cable kamabonakude i-50ohm iyafikeleleka ngezaphulelo ezikhulu zamalungu, ikuvumela ukuba ukhethe phakathi komlinganiselo ongakumbi nceda iimfuno eziluncedo. Kwaye, ukufumana amandla okukhetha kubavelisi abohlukeneyo, kuya kufuneka uthembele ukuba into eqhelekileyo malunga nenqaku iya kuyifumana ngokukhawuleza kweyakho ukuba yenye yezona zinto zisebenza ngokwenene.
Ukuba ubufanele ukuba uzama ukufumana intambo esebenza ngokuphezulu icoaxial ewona mgangatho wophawu usebenzayo kwaye iyaguquguquka ukuba isetyenziswe kunye nee-eriyali ezininzi kunye nezixhobo zothumelo, jonga kwi-RG174 ephezulu intambo yeCoaxial engu-50ohm ye-Antenna. Le nkqubo lutyalo-mali olubonelela ngomgangatho ophezulu usebenzisa ukucaca komqondiso kunye nokhuseleko onokuthi ulufune kuninzi lwesandi kunye nokuhanjiswa kwevidiyo.
