Question re: running coax cable in newly finished basement
I am finishing my basement and running new coax cables. 3 of the cables (incl the one that feeds my wifi) will be buried in the joists under the sheetrock ceiling. I thought I would run those 3 cables thru a 1.5 inch PVC pipe for about 18 ft to an access point. If I ever need to replace one, I can easily feed it thru the PVC pipe.

Any problems with running 3 RG 6 coax cables that close together??

Thanks

You may want to reconsider using sheet rock on the ceiling. We have it in our basement and I need to access a few locations and cannot without making a big freaking mess. A nice drop ceiling is a beautiful thing if you ever need access or spring a plumbing leak.

With that said, all of our coaxial cable is bundled together for a good 10-12 feet, maybe a dozen or so cables and no issues. Run a piece of pull line with them too just in case you need to pull something later at technology changes.

I'll second the drop ceiling. I hate drywall ceiling in a basement. The basement is about the last chance you have to change anything across a house.

I think that the coax shouldn't theoretically be able to interfere (electrically) with each other.

No issues what so ever.

No problem at all. Run a pull string with the cables, leaving a couple of extra feet on string at each end. It will make life a lot easier if you need to pull more cable in the future.

thanks. wife hates suspended ceilings, so drywall it is. main bedroom (w/ egress window) has no pipes above it. main living area has just a couple of joints -- I guess I'm willing to take a chance on that. Second bedroom (no egress window) has a lot of pipes above it. I still may put a suspended ceiling above that "bedroom" -- or keep some spare sheetrock on hand!!

No problem running multiple coax and/or CAT5/6 together. You need to make sure you have a physical separation or adequate distance between these low-voltage cables and any AC power cables. Conduit is a great idea, as is leaving a pull line. Termination is critically important.

Run the PVC, but run the current cables OUTSIDE of it.
The conduit is for FUTURE, don't fight the current cables by filling it up already.
Run some cat5e too. No concern running RG6/Cat5e together. You can buy multi-core with them bundled together.

Everything he just said. They don't carry enough current to create EMF/EMI. DO NOT run parallel to power, crossing is fine though.

Get Quad Shielded, CL2 rated, 3mhz tested RG6. It's barely more expensive than standard, but give you additional shielding from interference. You do have to use RG6-Q connectors though, the cable is slightly larger because of the additional shielding.

If you can have an electrician or cable guy terminate the ends and use COMPRESSION connectors not screw on connectors.

ETA everything snidera said too!

Nit (in the current context): UTP cable is not "coax." Coax is a single (center) conductor surrounded by a shield. UTP cable is three twisted pairs. Completely different things and obviously not interchangeable.

There wouldn't be a problem running either as you plan, or a mix of the two.

While it's best to cross power cables at right angles, common 120VAC 20A household circuits won't present much noise to UTP or coax. Stay away from fluorescent and LED fixtures, as well as motors and other things that generate strong fields.

Be cautious running the UTP. Do not stretch, twist, bend sharply or kink the cable. Coax will have a minimum bending radius, as well.

I dislike ceiling tiles, too.

Tie off the string at each end.
Cleaning up the house just after buying it I was going crazy with the vacuum cleaner and it grabbed ahold of a string in a junction box. Frown

I tend to go overboard on design and construction, but that's over-kill even by my reckoning.

I did my own run before having cable Internet installed because the cable modem had to go in the exact opposite corner of the house from the service entry. I used Belden 7915A Duobond Plus® Shield. It's got to be about a ±125' run. Twice cable techs have been out here for installs: Once for the original install and then for the upgrade just a couple months ago. Signal in the computer room is as good in all respects (signal levels, SNR) as at the end of the cable company's drop.

Belden 7915A actually has better shielding than some quad-shields, incl. Belden's own 7916A, and you can terminate it with standard RG6 connectors. I use compression connectors and a Paladin Data Shark kit.

Have to be careful with turn radius on Belden 7915A, and excessive pulling. 7916A QS is more robust.

Just happened to see this and remembered your thread. Might provide some basics.
