Hi there,

Is there someone here who is expert on electrical? I need help on running coaxial cable to my existing walls. I have a 1st floor where I have access to drilling holes into the second floor. I am willing to cut open holes for installing the single gang boxes. Now, here are my questions.

1. Which in wall boxes should I get for existing walls? Where do I get them?
2. what type of coaxial cable should I use for Digital video?

Thanks guys.

Just use the same old junction boxes as for any other electrical. Old work boxes are slick for retro fits. You just cut a hole to fit in the drywall and tighten up a screw on the side to clamp it solid. No trying to nail into a stud. You can buy plates with the F style connectors or other things too, telephone, ethernet, etc. I have one where my cable comes in with an F style and an ethernet. Home centers and electrical supplies have them.

Not sure what style cable.

To add to labman's info, look for , at the big hardware stores, "old work" boxes made for data, they have no backs to the boxes or rings.

Use RG-6 CATV coax cable rated for Digital , and the best crimp- on connectors you can buy. There is a special tool to crimp, usually comes in a kit.

The connectors can be a little challenging, so buy extras and practice. May need to get a stripping tool for the best connection, as there are four layers till you get to the copper wire, and each layer needs to be cut differently. A how to book will help.

Attached is a picture of one of the old work data boxes that tkrussell is referring to (I think). The problem with using regular electrical boxes is that it's hard to get the cable out of the box without bending it too much which can compromise the shield.

Actually, I don't think that code even requires a box for this. My cousin is a CATV installer and he gave me some wall plates that attach with these screws that have real deep threads. You just screw them right into the drywall. I've used a few of them already, and they work great. If you're not fishing the cable (like coming through the wall from the outside), all you need is a hole big enough for the cable, and then you just screw the plate to the wall. If you're fishing the cable you can put a bigger hole, as long as the plate covers it. The only problem is that I can't seem to find these plates anywhere. I'm going to ask my cousin where he gets them.

I think Home Depot and the local professional electrical supply had the plates, at least plates with holes and modules. Radio Shack and Ace hardware have F style plates.

When fishing from 1 location to another, Consider From underneath, from above and through other walls, coming down from the attic(or up from below) through a closet and out to other side is sometimes an option.
