Chidule cha Zamalonda
Mtundu wa chingwe cha RG 174 coaxial ndi RG174.
Gulu la Coaxial Cables
Chingwe cha 50Ω chimagwiritsidwa ntchito potumiza digito. Chifukwa nthawi zambiri amagwiritsidwa ntchito pofalitsa baseband, amatchedwanso baseband coaxial cable. Mtundu uwu wa 50Ω baseband coaxial chingwe umagwiritsidwa ntchito makamaka potumiza siginecha ya baseband, yokhala ndi bandwidth pakati pa 1 ndi 20MHz. Basi-mtundu wa Efaneti (netiweki yanthawi zonse ya makompyuta) imagwiritsa ntchito chingwe cha 50Ω coaxial. Mu Efaneti, chingwe choonda cha 50Ω coaxial chimatha kufikira mtunda wopitilira 185 metres, pomwe chingwe chokhuthala cha coaxial chimatha kufikira 1000 metres.
Chingwe cha 75Ω chimagwiritsidwa ntchito potumiza analogi ndipo chimatchedwanso Broadband coaxial cable. Amagwiritsidwa ntchito kwambiri pamakina a CCTV/CATV. Makina a CATV, omwe amadziwika kuti ma cable televizioni network (otsekedwa-makanema a kanema wawayilesi), amagwira ntchito yayikulu pamakampani olumikizirana. Maukondewa amagwiritsa ntchito 75Ω Broadband coaxial chingwe kutumiza ma siginali, ndipo bandwidth yawo yotumizira imatha kufikira 1GHz.
