Funny you should ask, I'm doing such an install right now...
Belden makes great cabling, as does Canare and Liberty wire https://secure.libertycable.com/index.php
(Don't worry, you don't need to log in to browse cable specs, etc. Use the links on the left)
Generally speaking, you would use the following:
Composite vid: RG-59
Component vid: RG-59 (or RG-6, a lot thicker, only really necessary if the run is much over 60')Very important:
For the RGB (component) run, the cables must
be carefully cut to within 1" of the same length!!! Any error beyond that can cause color shift and video distortion. I usually measure the run with my fish, then lay out and cut all three lines (marking them as I cut each) then bundle them together.
Fot the audio, don't use coax! you'll need either two runs of Belden 8451 (2 conductors with foil shield) or one run of Belden 8723 (electrically the same as 8451, but with two pairs, each foil shielded.) With the 8723, I split the pairs and use heat shrink, leaving the foil in place. Makes for a nice connection. (I'll try to get a pic to post here with the moderator's approval.)
And for the audio, no matter what cable you use, connect the foil shield/drain wire at one end only!! (The source device end, not the tv end.) All coax/video shields connect at both ends.
Most of the consumer-grade stuff uses RCA plugs/jacks. Use gold-plated plugs and jacks, especially on the video connections. If you have a local electronic supply house (NOT "Rat Shack") they should have RCA plugs made specifically for RG-59/6 coax. My local house has them in both solder-on and twist-on styles.
You may email me for more tips and/or questions.
