You can use either: Belden 89259, 1506A, or the most recent favorite, the 1695A.

All of these will benefit from adding additional copper braid shielding, which you can get from a large diameter coaxial cable, say at RS, and strip off the outer jacket, and then carefully loosen the copper braid like chineese handcuffs, pushing it along the length of the coax core, and remove.

Then use this scrunched braid to slide over the outside of one of the afore mentioned cables, stretch it out tightly, and solder it to the source end RCA ground ONLY, and then at the other end, connect the load end of the cable's added outer braid to a 0.01 uF disc ceramic capacitor (also available at RS), and the other end of the cap to the load RCA ground. Do not let the braid touch the load end RCA shell or ground, use HS or tape to isolate it.

The overall assembly can be covered with HS, or techflex, or just wrapped in teflon plumbers tape secured at the ends with some vinyl tape or HS.

This leaves out some of the details, such as the RCA plugs, etc.

See the Cable Asylum for such details, use search or check the archives.
