Package Includes: 1 pc BNC male plug to 2x 4mm dual banana female jack socket binding post connectors. What it is: A BNC to dual banana binding post adapter that converts a single BNC signal into two 4 mm banana outputs (red and black). Material and build: BNC terminal connector with ABS plastic shell and copper contact; antiacid, antimildew and electrical insulation; sturdy construction for reliable use. Easy to connect: With the help of an RF coaxial radio antenna splitter, connections can be made to the binding posts by spade lugs, banana plugs or wire leads. Plug and play, no soldering required. Function and compatibility: Adapts a single BNC plug to two 4 mm banana jacks to provide isolation for a fourterminal network. The signal is connected to the red terminal. Practical performance: Binding posts facilitate connections of test leads or additional components. Enables splitting a single BNC signal to two banana outputs for testing or measurement setups. Use scenarios: RF lab testing: connect a single BNC source to two measurement instruments or devices for simultaneous monitoring. Antenna experiments: feed two components from one BNC source with isolated channels. Calibration and testing: route signals to different test equipment while keeping channels isolated.
