I ended up running coax, speaker wires, and CAT 5e alongside each other in some places, and alone in others. I also tried my best to keep the low-voltage wiring away from line-voltage wires (inside conduit), or if they had to be near each other, at least have them cross at right angles to minimize any cross talk. And so far, we haven't had any problems with data, video, or audio.

Thanks all for the replies! You all make good points about cable traffic. Most of the run for these wires will all be outside of any conduit. There's only a small portion (12 feet) going under the floor through a 1.5" PVC 'conduit'. But I will certainly be careful about running alongside any AC power lines - I also found that crossing powerlines at right angles will result in minimal interference. Thanks again!

In the cat5 cable all the pairs are twisted to reduce crosstalk and inductance. I would skip running the cat3 and run an additional cat 5 for the phone wire. The RG6 is shielded and should not cause any interference issues. Do not pull romex through the same chase as that has the potential to cause interference in the cat5 lines. Good luck.

looking good j! about the wiring, think about bigger installations such as schools that have computer labs. They run a bunch of cat5e cables together in a cable tray and get no interference. considering you are only going to have a few cables, you shouldnt have a problem. most of the interference you can get is from power wires, not really from signal wires such as the ones you are using since they dont have enough magnetic field associated with them to cause any affect that you can notice. are you using 3/4" conduit?

glad the house is going well.

That's a good question. The short answer is it depends on the quality of the cable. If you have good CAT 5e, then you will have no problems, even with the speaker wire. The only place I can see a blead over problem is with the phone (CAT 3) into the computer network. There should be no troubles with the RG-6 or the speakers. Use good quality (Leviton or Hubble) RJ-45 connectors for your ethernet (computer) and you should be all set.

I used to pull cable at AMD. I doubt you'll get any crosstalk. If you've never seen under a data center floor....its just...not pretty.
