Shielding coax from parallel electrical wires

Hello all,
Longtime lurker, first time poster. I am doing a partial basement renovation (bathroom and bedroom) and intend to run coaxial cable (RG-6) to the new bedroom. My problem is that the only path that I have available to run the cable (along a structural I-beam that runs down the center of the house) is also the location of 2 or 3 NM electrical cables that take advantage of the same pathway. At present, the Romex and the coax run in parallel for approximately 20 feet. For various reasons, I cannot relocate either without dramatically increasing the scope and cost of this project.

Everything I've read says to keep coax 6-12 inches away from electrical cable. Since that is not possible in my case, is there any kind of additional shielding I can apply to the coax, or is there special coax manufactured for situations such as these?

Thanks for the consideration.

If your coax shield is properly grounded to earth will be fine....

Your ac power is 60Hz.....the coax signal is 100MHz to 1Ghz.......Even Chinese made video equipment will have a balun on the coax end....the 60hz will not get in.


Even if you are on the right track, you will still get run over if you just sit there.

COAX is already shielded. 20' is not going to hurt anything.
Sometimes I feel like if I answer any more questions it is like someone trying to climb over a fence to jump off a bridge and me giving them a boost.
