Isidibanisi se-BNC saphuhliswa ngu-Paul Neill osuka kwi-Bell Labs, kunye neka-Amphenol eyakhe, uCarl Concelman, kungoko efumana igama elithi “Bayonet Neill–Concelman(BNC)”.Iqale yenzelwe usetyenziso lwasemkhosini njengesidibanisi esikhawulezayo sikanomathotholo.Ngokudibana ngokukhawuleza, i-75 ohm impedance kunye nozinzo ukuya kuthi ga kwi-11 GHz, izihlanganisi ze-BNC zisetyenziswa kakhulu kwimarike yosasazo kunye nonxibelelwano namhlanje.
