I assume the signal is sent down the center wire and believe that solid copper is better than the copper clad steel. Is the Quad Shield what it sounds like, just a shield to protect disturbance of the signal? The more protection the better?
Will standard cable with solid copper core be sufficient for my conduit protected cable? I will be running the power and signal cable through the same conduit, so should quad shield be used?
Is Quad shield with copper clad steel better than normal shielded solid copper core?

You see.. I am a newbie, but just want to get the best possible signal...
Relative to signal, I doubt that you'd see a difference between the various types. I tend to use relatively cheap stuff myself. I bought a big spool from Sadoun several years ago. The only thing I would comment on though, is whatever type you get, try to make sure that the connectors and crimper, if you use crimp type, are compatable with the type cable you get. It makes things a lot easier if putting a connector on only takes a minute rather than being a 10 minute process. For the inexpensive cable I use, the cheap RS connectors and a crimper I also got at RS work fairly well, although I would prefer that the crimper was a slightly smaller size, as to get it to work well, I need to wrap something around the connector barrel or it doesn't bring it down quite small enough.

But the cheap connectors with the cheap coax is pretty easy to work with. The inner barrel of the connector slips in between the outer insulation and the metal shield, so that with a cheap coax stripper I have, I can strip a half inch of insulation/shield off the center conductor, then slip in the connector (using a small vice grip, as it takes a bit of force), pushing it in until you see the center insulation start to come through the hole in the connector. Then I crimp it and trim off the center conductor. Whole thing takes about a minute.

Since you're about to try to fish coax through a conduit, another technique is to tie a cotton ball onto a fishing line, and put it into one end of the conduit, then take a vacuum cleaner and suck on the other end of the conduit, and zap, it will suck the cotton ball and fishing line through. Then you can pull heavier line back through, and pull the coax with the heavier line. It's good to pull another length of heavy line through with the coax, so you'll have it ready for whenever you need to pull another length of coax through.

Sadoun has censored my signature for no good reason, which is annoying.
