Monoprice 121679 Coaxial RF Cable 1.8288m 75-ohm 97% OFC Double Shielded 22pF CL2 Onix Series

Digital coax cable for S/PDIF and line-level RCA

The Monoprice 121679 is a 1.8288 m coaxial RF cable built with RG-6/U construction and 75-ohm impedance. It uses 97% oxygen-free copper conductors and double copper braid shielding to protect S/PDIF digital audio, composite video and other line-level RCA signals from EMI and RFI interference. The CL2-rated jacket meets residential fire-safety requirements for in-wall routing. A braided nylon sleeve adds abrasion resistance while keeping the cable flexible.

F-Type connectors on both ends suit wall plates

Two male F-type connectors terminate the cable, so it plugs directly into wall plates, subwoofers, DACs, AV receivers or any component with matching F-type jacks. The RG-6/U diameter fits standard keystone openings and conduit without special tools. Because the jacket is CL2 rated, the cable can be pulled through stud cavities or behind baseboards without violating building codes. The braided nylon exterior slides past insulation and framing without snagging.

Low 22 pF per foot capacitance preserves signal

The double copper braid shield and foamed dielectric keep capacitance at 22 pF per foot, reducing high-frequency roll-off on digital audio streams. Oxygen-free copper conductors minimise resistive loss over the 1.8288 m run. In normal use the passive cable generates no heat, draws no power and adds no audible noise to the signal path. The nylon braid remains pliable at room temperature, so repeated routing adjustments do not fatigue the jacket.
