BNC Male to BNC Double Female Splitter- T-Type One Male to Two Female RF Connectors(Bayonet Nut Connector) is a miniature quick connect/disconnect RF connector used for coaxial cable. It features two bayonet lugs on the female connector; mating is achieved with only a quarter turn of the coupling nut. BNCs are ideally suited for cable termination for miniature-to-sub miniature coaxial cable (e.g., RG-58, 59, to RG-179, RG-316). We often use BNC cable to transmit audio and video signal in monitors and audio equipment in the up-markets.
