Coax TV cable compatable with power cable

I have cable TV in the house and want to run it out to a detached garage using a splitter. I am running 2-2-4-6 direct burial cable (240 volts)to the garage for power.

My question is can I put the coax cable for the TV in with the direct burial power cable without getting any interference with the picture on the TV?

Not a good idea, even though the TV cable is shielded it could pick up induced voltage from the 240vac. In industry we make a point of running low voltage (24vdc, 1-5vdc) in a separate conduit or cable tray away from any and all higher voltages.

At my old house, I had the TV cable in the same underground pipe as the 220.....It worked fine.....not saying yours will....just saying mine was OK

I wouldn't. At the very least it will muck up the signal. At the very worst, I think placing a load on the 240 can make some pretty impressive induced voltage in anything around it, so you run the risk of frying the tuner in all of your TVs on the circuit.

Standard code here says 18" away from 240v, 12" away from 120v. Most electricians just run it in the next studspace so its 16". I have also put my outlet boxes on either side of the same stud with no problems, but the cables are run on the next stud away, so they're only together for the last couple inches.
