RG6 running parallel to 220 wire...is it bad?

[VOLBEAT]

A loooooong time ago('97 to be exact) I put up out first dish, ran the RG6 right into the attic, and straight across to the top plate of the living room wall where the tv is, and the wall cavity that was directly behind the tv happened to be the same wall cavity that the 220 wire that goes to our electric range is. I thought nothing of it, and don't think any picture problem we ever had was due to that. But, I've heard more than once that you shouldn't have your RG6 in the same wall cavity as 220, so I re routed, simply so it could never be a problem, no matter what. I went down another spot through my heater closet, under the house, and ame up through the floor, right behind the tv, No big deal, but crawling under the house is kind of a pain, but if it's necessary, I don't mind it. I'm about to run another length of RG6 for my HR20 install Nov.3, and I wouldn't mind not going under the house, and going straight to that same spot, and down the wall cavity. Much easier, but last time I didn't have this site to ask this question, so I figured getting a consensus here would make my decision. There are a lot of smart people here, so what do you in the know say about this? Thanks in advance and I really appreciate it. This site is just awesome, and am glad I found it.

High quality RG6 Quad Shield cable should not be affected by any stray interference with your 220V electrical wiring. If you were running analog cable TV or an off-air antenna it might be more of a problem, but digital satellite signals should be fine.

With the digital signal it should be fine, If you are not having any problems I would not worry about it.

This is the cable I'm running

So, I'm fine going down that same wall cavity with this?Quad shield is harder to manuever, and overkill in my situation except for maybe the 220 wire.
I might be able to move over one, this particular one is ideal, as far as location that's all.

That is a very good cable and has as good or better shield characteristics as quad shield cable. I would not hesitate to use it in your wall pull.

When the load of an electric range is clicked on or off, there can be a large reflected pulse back up the power cable. It is similar to the inrush reflection of a motor but more narrow.

If you can easily separate the cables, I would.

Even if you can just keep the wires 6 inches apart in the same chase it would reduce possible problems. The RF component of the reflected pulse is almost exclusively near field (close by) at 220V.

Thanks for the responses so far..........a little mixed, which makes me think maybe I should just eliminate the possibility of a problem, no matter how remote, by just running the second length right along with the existing one that goes to my H20, which is a little bit longer run, and requires going under the house, which is just a dirty job, but not the end of the world. The cable is about 70 feet, give or take a couple feet, as opposed to maybe 40-50 feet going straight through the attic and down the wall. I like that idea, but would probably just pick another cavity.........I think anyway.

Just to clarify......if this caused any sort of problem, even if minor, would it be only
when the range was clicked on or off, or is the fact that is always current cause for possible concern also? I only ask because I already have a remodel box in this area of the wall, and is obviously the most convenient, but I could fairly easily go to the next wall cavity over, put in a new remodel box, and just eliminate the 220 from the equation completely. It might be the same cavity that a normal 110 electrical outlet has it's romex in............that isn't a potential cause for concern, is it? Thank you very much!

Not at all, There is no need to be concerned about romex, SE cable, 6/3 with ground, or whatever you are using for the range, being in the same space or even in the same drilled hole.

RFI on the receiver cables is the only concern and as Milominderbinder2 pointed out, the range cable can have a field of influence of aproximately six inches during operation. Keep the receiver cables more than six inches away from the range cable and you should be fine.

Thanks again! Yeah, the bad part is I know for a fact that the 220 wire for the range isn't fastened to the stud on one side of the wall cavity like it should be.......it's just in there loose. Not right, but it's a track home, and these are the kinds of things you sometimes find, so I'd have no way of knowing if I was 6 inches away or a half inch, so I'm best off going to the next cavity, just to be safe. Now, I wouldn't need it 6 inches away from romex. correct? Sorry to be a pest, just want to do it the best way, and once!:D

When electricity flows there is a small electromagnetic field generated around the conductors, it's just the nature of the beast. I would not worry about proximity to your outlet and lighting (romex) wiring.

The shielding (like in your Belden cable) will provide adequate RFI protection.

O.k., then next wall cavity it is! Thanks again!
