Uhlolojikelele Lomkhiqizo
Imodeli ye-RF coaxial cable RG58 yi-RG58.Ukwakheka kwekhebula elikhoaxial kusekelwe kumgomo othi "coaxial line", lapho amakhondaktha angaphakathi nangaphandle alele eksisi efanayo, phakathi kwawo kukhona i-dielectric evikelayo. Lesi sakhiwo sihlanganisa inkambu ye-electromagnetic kumakhondaktha angaphakathi nangaphandle. Ngokuvumelana nezibalo zika-Maxwell, lokhu kunciphisa ngempumelelo imisebe kazibuthe kanye nokuphazamiseka kwangaphandle, kuzuze{4}}ukulahlekelwa okuphansi,{5}}okuphakeme{5}}ukudluliswa kwesiginali. Izinhlaka zayo zokusebenza eziyinhloko zihlanganisa i-impedance yesici, isivinini sokusabalalisa, kanye nokungaguquki kokunciphisa. I-impedance yesici inqunywa i-radius ye-conductor yangaphakathi nangaphandle, kanye ne-dielectric constant of the insulating dielectric. Amazinga asetshenziswa kakhulu e-impedance we-50Ω kanye ne-75Ω asekelwe ekuthuthukiseni ukusebenza kahle kokudluliswa kwamandla kanye nokunciphisa ukuboniswa kwesignali kuzimo zohlelo lokusebenza ezihlukene.
