re: New construction - run coax?
Built recently and I ran coax and cat 6 to each TV location.

Better to have it there than not while running it is easy.

Beyond all of the previous suggestions, you might even consider a nice conduit / pull-box run for a few central spots: media center, office, wiring closet.


This is the best solution, no one knows what will be available in 10 years. If the house will have attic access over most of the rooms, run a plastic conduit from your in wall boxes up through the top wall plate leaving enough in the attic to extend above any insulation. Cat, fiber, coax, speaker wire can be easily added or removed as needed. Doing it yourself should only cost about 3 bucks per wall drop, 1 1/2 inch PVC will be fine.

re: New construction - run coax?
i am running coax to each room for now. From what i read this is the standard for now, but who know what the future will be. I hope to drop at least 2 runs of cat 6 as well. I was told to run a empty 3/4 conduit from outside to my media closet for the option of fiber, it is in my area.

re: New construction - run coax?
I'd do a larger conduit than 3/4". You can't fit shite through that.

ETA: I do this for a living.

re: New construction - run coax?
I cannot speak on the subject of what you should run, but I would suggest you also run PVC pipes from where the lines enter the wall to where you want the wires to come out. I would also go as wide as you can fit between the walls. This saved me twice as I did not consider running 2 coax cables (1 for cable box, separate for modem) to avoid unnecessary splits. Plus I wanted to run another HDMI from my TV for when I need to hook my laptop to the TV.

I left a gap between the pvc and walls, and kept getting snagged in the insulation (sound proof/reduction) when running the HDMI from the TV to the laptop.

re: New construction - run coax?
Did this two years ago. Coax to every room for TV, several CAT 6 to every location a TV or device MIGHT go. Also ran CAT 6 to the attic (for a high-up AP) and to the corners of the house and porches for security cameras. All terminates in a closet that has CAT- 6 and Coax to the outside where the Internet providers will have their demark. No regrets, and looks of admiration from the neighbors.

If I had thought of it, I would have buried a CAT 6 out to the overpriced mailbox for a surveil camera there too!

re: New construction - run coax?
If I were building a house, I'd run conduit down the walls in likely places for both coax and ethernet, and either put blank plates there or leave the wall uncut if no cabling is dropped there.

In the future, the conduit allows you to put whatever kind of cabling you want straight down behind the targeted area of the wall, and you can cut out and put whatever plate and connector you want in.

My only opportunity to test with this, I just had conduit run from attic to basement, which helped for new cable runs, but was still limited.

We use petroflex down here which snaps right into the low voltage boxes. Guys call it smurf tube.

We're doing the same on the residential prewires we're doing.

I still can't believe that I got back into residential. We're doing prewires for three A/V companies here.

re: New construction - run coax?
Thanks for all the replies. Am planning to run 2 Cat 6 to every bedroom, and 4 to the living & game rooms. Will also run coax as well. Didn't think I needed it, but I think all of the affirmatives have let me know that I should go ahead and do it. Also, looking at smurf tube or pvc. Likely 3/4 - 1 inch in most rooms and bigger in the rooms with more cables.

Do I need to go ahead and run HDMI as well? Started searching on monoprice for all of the cables, connections, switches, etc. and my bill has racked up quite nicely.

re: New construction - run coax?
It adds up quickly.

The companies we run cable for have us run three CAT6 and one RG6 to each 4K TV location and one CAT6 and one RG6 to a regular TV location.

Also, any good places to look for smurf tub? Seems pretty expensive when compared to the actual cables when I look it up. Home Depot has it for $70 for 100 feet. I'm ordering 2000 feet of cable (and yes I realize that I can put multiple in one line), but, damn that gets expensive.

Why three? For the main TV watching areas I was doing 4 each. 1 for TV, 1 for XBox, 1 for DVD player (not completely necessary), and then 1 extra for another system.

re: New construction - run coax?
I ran to every room of my houseto a central location in my attic. I installed a lomg range antenna up there. The only reason I did this was just in case of Mother Nature knocking out power for an extended period of time. I also pre wired my house to hook up a generator to my house panel. Living through the aftermath of hurricane Gustav and not having any tv to watch was miserable. To me that is the only advantage to running coax. Especially if it is new construction now is the time to do it. Even if you never use it, it’s nice to know I have that option if necessary. One other thing. If you pre wire for a generator make DAMM sure you have a way to isolate the main feed coming into your house.

re: New construction - run coax?
They’re probably sending it in over a video distribution system. One of them only does Crestron systems. These are $1.5 million base price townhomes in Chevy Chase, MD so I’m sure there’s a control and distribution system in place.

re: New construction - run coax?
What size would you recommend? From what I have read, you can only drill a hole with a diameter of 40% of the board if it’s a load bearing wall. This ends up being 1” tubing. I was thinking of running two 1” tubes behind each tv.

re: New construction - run coax?
Two 1" should be fine. Your individual holes (according to code) are to be no more than 1/3 of the stud. We drill 1 1/4" holes for our main chase down the house. Just separate your holes a little. Don't join them. Never drill through laminated beams. Big no-no.

HDMI, Ethernet, Spare/control

You can buy structured wire that’s already bundled with the cats and coax.

If you think wire is expensive wait to you started buying the baluns to convert all those. Like VA mentioned typically you would use just one cat for HDMI with some type of video distribution.

re: New construction - run coax?
TigerWise, now you've gone and thrown me for a loop. I thought when he mentioned he was running three drops that he meant three cat 6 drops. Are you saying that one of those three would be HDMI, or are you saying that I can run HDMI through Cat 6? In other words, I wouldn't need to run a HDMI, as I can do that with cat 6?

Also, what do you mean by structured wire that can bundle cats and Coax? I haven't seen those before.

And finally, "balun"...that's a new term for me. Can you explain to me what that is, and how many I would need?

Thanks for the help.
