Ukuba ufuna ukuhambisa umqondiso, njengeprogram yeTV okanye uqhagamshelo lwe-Wi-Fi, enye into ngaphandle kwentambo eqhelekileyo iyadingeka kulo msebenzi. Uhlobo oluxhaphake kakhulu lwentambo esetyenziselwa ezi njongo lwaziwa njenge kwaye lufana nentambo ye-coaxial, “ Olu didi lwentambo luqulathe i-conductor esembindini ephethe umqondiso kwaye ivalwe ngo maleko wokugquma oyikhuselayo kumonakalo. Ezi maleko zinceda ukugcina amandla omqondiso njengoko uhamba. Kodwa kukho iimeko apho uphawu lunokuthi lube buthathaka njengoko luhamba kwintambo. Ukuba usuka kude kakhulu nomthombo, oye ube buthathaka ngakumbi njengoko umqondiso uhamba emoyeni okanye phantsi kwentambo, ikhompyutha yakho inokuyeka ukuyiva; oku kubizwa ngokuba "yilahleko yesignali," kwaye inokwenza buthathaka okanye ivale uphawu.
Yintoni i-RG58 kwaye Kutheni Ibalulekile?
I-RG58 luhlobo oluthile lwentambo ye-coaxial. Luhlobo oluthile lwentambo, idla ngokwenza indima yonxibelelwano ngokwerediyo kunye nekhamera yokhuseleko. Ilahleko kwi-RG58 ibalulekile njengoko ithumela imiqondiso kumgama kwaye okukhona ilahleko eninzi onayo ixhomekeke kwizinto ezimbalwa ezahlukeneyo. Le lahleko inokwahluka ngenxa yezinto ezininzi ezinje, ukuba uphawu kufuneka luhambe ixesha elingakanani ukufikelela kwesinye isiphelo kwaye luhlobo luni lwesiginali oyithumelayo. ungasebenzisa i-analyzer ye-spectrum ukubona ukuba ingakanani ilahleko yesignali eyenzekayo rg58 intambo. Esi sixhobo sivavanya umgangatho womqondiso kwiindawo ezahlukeneyo kwintambo, ekuxelela ukuba ingakanani intambo elahlekelwe ngumqondiso wayo.
Amandla oMqondiso ayahluka ngokomgama
Enye into ephambili yokulahleka komqondiso ingabalelwa kumgama kwi-RG58. Loo ntambo yindawo enokumelana okuphezulu echasa ukuhanjiswa komqondiso - okukhona inde, kokukhona umqondiso uba buthathaka njengoko udlula. Ukuze ufumane ingcaciso engcono, makhe sithathe umzekelo: Ukuba usebenzisa Rg58c wena ukusasaza isignali yeTV iinyawo ezimbalwa kuphela, njengokusuka e-eriyali ukuya kwigumbi lokuhlala, umqondiso usenamandla ngokufanelekileyo. Ngapha koko, ukuba usasaza loo mqondiso kumakhulu eekhilomitha ukusuka kwinqaba kanomathotholo ukuya kwi-stereo yemoto yakho, umqondiso uphelelwa ngamandla amangalisayo. Qwalasela oku njengoko usenza iinkqubo ekufuneka zigqithise imiqondiso kumgama obalulekileyo.
Ukubala Ilahleko yoMqondiso
Ukuba ufuna ukufumanisa ukuba ingakanani ilahleko yesignali eyenzekayo kwi-RG58, kukho ifomula eyahlukileyo. Ngokuxhomekeke kwithuba elide kangakanani ikhebula, kwaye luhlobo luni lwesignali oyithumela ngayo, le fomyula iyatshintsha ukubonisa ezi zakhiwo ezahlukeneyo. Ngelixa le fomyula isenokubonakala inzima ungafumana izixhobo ezininzi kunye nezixhobo zokubala ezikwi-intanethi eziza kukwenzela izibalo. Esona sizathu sokwenyani sokwazi njengelahleko yesiginali kukufumanisa ukuba ulahlekelwa ngokwaneleyo ngumqondiso wakho ukuba ubuthathaka kwinqanaba lokufikelela apho ufuna ukukhanya kwalo. Oku kufana nokuqinisekisa ukuba isibane sakho sesibane somelele ngokwaneleyo ngaphambi kokuba ungene kwigumbi elimnyama.
Ilahleko yoMqondiso ngaphezu kweemitha ezili-100
Okwangoku usenokuba uyabuza, ingakanani ilahleko endiza kuyibona emva kwe-100m yentambo ye-RG58? Ewe, oko kuxhomekeke. Isantya apho umqondiso uhamba kunye nokuthembeka kwentambo esetyenziswayo. Ngokwesiqhelo, ungaphulukana ne-9 decibels (dB) yamandla ophawu nge-100 yeemitha ze rg58u intambo rhoqo 100 MHz. Mandiyibeke ngamanye amazwi, xa unento eyomeleleyo njengeewathi ezili-10 ukusuka ku-A kunye neeyadi kamva kwisiphelo se-B saloo ntambo ye-100m awufumani ngaphezulu kwe-1 watt. Kodwa yithi usebenzisa intambo engcono - i-RG213 okanye njalo; oku kuya kunciphisa ilahleko yomqondiso kunye nomgama ofanayo kunye nokuphindaphinda.
