Lub hom phiaj tseem ceeb ntawm 50 ohm coaxial kab yog xa cov ntaub ntawv qhia hauv ob txoj kev sib txuas lus. Cov piv txwv ntawm daim ntawv thov suav nrog: kab rov tav thaum lub khoos phis tawj tsim Ethernet, lub tshuab txuas xov tooj cua wireless, cov kav hlau txais xov GPS, thiab lub xov tooj ntawm tes. Cov khoom sib dhos cable tau teev tseg hauv ntu no npog feem ntau siv RG series coaxial cables thiab txuas txuas rau cov ntawv thov saum toj no.
Lub hom phiaj tseem ceeb ntawm 75 ohm coaxial cable yog xa cov duab video. Daim ntawv thov uas raug ntau tshaj yog xa cov kab hluav taws xob TV, yog li nws qee zaum hu ua&"; teeb liab pub &";, thiab feem ntau yog nruab nrog F-hom txuas. Lwm daim ntawv thov sib xws yog kab ntawv kab video xa mus rau cov khoom siv rov ua dua, xws li txuas DVD player, kaw video, thiab tsav tsheb. Lub sijhawm no, nws tau hu ua kab thiab suab (A/V) kab, uas feem ntau yog nruab nrog BNC thiab RCA txuas. Hauv ob qhov piv txwv thov saum toj no, RG59 thiab RG6 coaxial cables yog siv dav tshaj plaws, ntawm uas RG59 suav nrog RG59B/U (ib leeg ib leeg ib txoj kab hlau txuas) thiab RG59A/U (ntau txoj kab nruab nrab xaim). Cov khoom siv sib txuas cable tau teev tseg hauv ntu no npog txhua qhov tshwj xeeb uas tsim nyog rau ob daim ntawv thov no.
50 ohm BNC txuas muaj cov insulator ntawm lub interface, thaum 75 ohm tsis muaj insulator.
