BNC Female Coupler for 50-Ohm Coax
This Monoprice 104128 coupler joins two BNC female connectors on 50-ohm coaxial cables such as RG-58, RG-8 or RG-60. The body and contacts are gold plated to resist corrosion and maintain signal continuity.
Installers Extending Cable Runs
Technicians needing a straight-through join between two terminated 50-ohm cables will find this part suitable. It does not convert between BNC and other connector types, nor does it split or distribute a signal to multiple outputs.
50-Ohm Impedance Match
The coupler is specified for 50-ohm characteristic impedance, so it preserves the transmission line properties of compatible cables like RG-58 or RG-8. Using it with cables of a different impedance will introduce mismatches.

Questions about this item
What comes in the box and do I need anything else to join two BNC cables?
The package contains the BNC female-to-female coupler only; you must supply the two 50-ohm coaxial cables such as RG-58, RG-8 or RG-60.
How do I choose the right version when the listing shows model 104128 and part number 4128?
Both numbers refer to the same 50-ohm gold-plated coupler; there are no alternative capacities or versions to select.
What does the 50-ohm rating mean when I connect this in my test setup?
It matches the impedance of 50-ohm cables like RG-58, RG-8 or RG-60 so signals pass without reflection at the joint.
