Coaxial Cable yog ib hom hluav taws xob xaim thiab cov teeb liab xaim kab, uas feem ntau yog ua los ntawm plaub txheej ntawm cov ntaub ntawv: lub puab tshaj plaws yog ib tug conductive tooj liab hlau, sab nraud ntawm cov hlau yog surrounded los ntawm ib txheej ntawm yas (siv raws li ib tug insulator thiab ib tug conductive tooj liab hlau, nyob rau hauv lub sab hauv ntawm cov hlau yog ib puag ncig los ntawm ib txheej ntawm yas (siv raws li ib tug insulator thiab a dielectric), thiab muaj ib txheej nyias ntawm mesh nyob rau sab nraud ntawm lub insulator. Tus neeg xyuas pib (feem ntau yog tooj liab lossis alloy), thiab tom qab ntawd txheej txheej txheej txheej ntawm cov khoom siv insulating yog siv los ua cov tawv nqaij ntawm tus neeg xyuas pib.
