Monoprice 121681 Onix Series Coaxial RF Cable 15ft 75ohm 97% OFC

Monoprice 121681 Onix Coaxial Cable

The Monoprice 121681 Onix Series is a 15-foot 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 signals from EMI and RFI interference. Gold-plated RCA male connectors sit at both ends. The CL2-rated jacket is wrapped in braided nylon for added durability and a clean finish.

Suited for digital audio and composite video

This cable works well for S/PDIF digital audio connections between components such as DACs, receivers or streamers. It also handles composite video and other line-level RCA signals. Buyers needing longer runs for whole-home distribution or installations requiring plenum-rated cable should look at alternatives. It is not designed for high-frequency RF applications beyond standard consumer audio and video bandwidths.

Check connector spacing and routing path

Verify that 15 feet (4.572 metres) reaches between your source and destination with enough slack for strain relief. Confirm both devices use female RCA jacks, as this cable terminates in male plugs on each end. Ensure the CL2 rating satisfies any local building code requirements for in-wall installation. The braided nylon jacket adds thickness, so check tight bends or conduit fill before pulling the cable.
